The rattle-type noise may be caused by torsional vibration of the balance shaft. http://local.underhoodservice.com/GM_Drivers_Rattled_By_Engine_Noise_Chicago_IL-r1350268-Chicago_IL.html http://local.underhoodservice.com/GM_Drivers_Rattled_By_Engine_Noise_Chicago_IL-r1350268-Chicago_IL.html Simple manual temperature controls are being replaced with digital push button settings and computer logic. Today's new car buyers want separate controls for the driver and front seat passenger, and triple-zone rear A/C in minivans and SUVS with a separate control head in the rear to keep the kiddies or mother-in-law comfortable. http://local.underhoodservice.com/The_Logic_Behind_Automatic_Temperature_Controls_Chicago_IL-r1350267-Chicago_IL.html http://local.underhoodservice.com/The_Logic_Behind_Automatic_Temperature_Controls_Chicago_IL-r1350267-Chicago_IL.html For the engine to start and run smoothly with no stalling, hesitation or misfiring, the injectors have to deliver the proper amount of fuel with every squirt. This is especially important on late-model engines with sequential fuel injection. http://local.underhoodservice.com/Fuel_Injection_Diagnosis_Service_Chicago_IL-r1350266-Chicago_IL.html http://local.underhoodservice.com/Fuel_Injection_Diagnosis_Service_Chicago_IL-r1350266-Chicago_IL.html Intermittent stalling also can be caused by a bad idle air bypass motor or idle speed control motor. If these devices fail to provide the correct idle speed, the engine may die. Sometimes the fault is in the PCM or the inputs to the PCM. The factory programming may not provide enough idle speed when the A/C is on, when the alternator is under high load or when the temperature is unusually hot or cold. The fix here may be to reflash the PCM with the latest OEM update. http://local.underhoodservice.com/Investigating_Intermittent_Stalling_Problems_Chicago_IL-r1350265-Chicago_IL.html http://local.underhoodservice.com/Investigating_Intermittent_Stalling_Problems_Chicago_IL-r1350265-Chicago_IL.html In this article, we'll take a look at some of the common problems that affect engine performance. With on-board diagnostics (OBD), many of these problems will cause a check engine lamp (CEL) and store a code. http://local.underhoodservice.com/Getting_Nissan_Engines_Back_to_Peak_Performance_Chicago_IL-r1350264-Chicago_IL.html http://local.underhoodservice.com/Getting_Nissan_Engines_Back_to_Peak_Performance_Chicago_IL-r1350264-Chicago_IL.html You can easily solve this safety problem for your customers, save them hundreds of dollars on headlight replacements, and bring in some extra service dollars to your shop at the same time. http://local.underhoodservice.com/Headlamp_Restoration_Chicago_IL-r1350263-Chicago_IL.html http://local.underhoodservice.com/Headlamp_Restoration_Chicago_IL-r1350263-Chicago_IL.html There is, however, one common denominator between today's air tools and ones made years ago. The element that all these tools need, which is many times overlooked or taken for granted. Here is a riddle for you: If a gasoline engine can't run without gasoline, then what does an air tool need to operate? You guessed it! Air! Pneumatic tools need air that is clean, dry, and the correct pressure and volume in order to perform the way they were designed. http://local.underhoodservice.com/Hose_Reels_Chicago_IL-r1350261-Chicago_IL.html http://local.underhoodservice.com/Hose_Reels_Chicago_IL-r1350261-Chicago_IL.html These tool shows were very well attended because they allow the manufacturers to show off their new stuff for the warehouse distributors and wagon jobbers. And soon you'll be seeing presentations on how the latest gadgets can save you time, bloody knuckles and lots of frustration. http://local.underhoodservice.com/Tool_Guide_Chicago_IL-r1350260-Chicago_IL.html http://local.underhoodservice.com/Tool_Guide_Chicago_IL-r1350260-Chicago_IL.html A vehicle's fuel level must be accurately measured by the PCM in order to detect evaporative leaks. Consequently, newer fuel gauge configurations often incorporate a small module that may require as much as 20 minutes to compute the actual fuel level in the fuel tank. http://local.underhoodservice.com/Fuel_System_Foul_Ups_Chicago_IL-r1350259-Chicago_IL.html http://local.underhoodservice.com/Fuel_System_Foul_Ups_Chicago_IL-r1350259-Chicago_IL.html All versions of Joe Gibbs Driven Hot Rod oil can be used in flat tappet and roller cam engines. After using Joe Gibbs Driven BR break-in oil for the first 500 miles on a new or rebuilt engine, customers can now run their choice of conventional or synthetic oil in their engine without having to worry about aftermarket additives. http://local.underhoodservice.com/High_ZincConventional_Oil_for_Classic_Cars_and_Historic_Racers_Chicago_IL-r1350258-Chicago_IL.html http://local.underhoodservice.com/High_ZincConventional_Oil_for_Classic_Cars_and_Historic_Racers_Chicago_IL-r1350258-Chicago_IL.html According to their engineers, these high-powered engines are ideal for all-wheel-drive applications used in Subaru vehicles because they are inherently compact — short and low. The layout concentrates its mass in a small area and contributes to a lower center of gravity. http://local.underhoodservice.com/The_Subaru_Boxer_Engine_Chicago_IL-r1350257-Chicago_IL.html http://local.underhoodservice.com/The_Subaru_Boxer_Engine_Chicago_IL-r1350257-Chicago_IL.html BMW has found it necessary to move to extended service intervals, involving condition-based oil changes and excessively separated maintenance inspections. Oil sludging, overheating problems and emissions faults are the direct result of the lack of reasonable maintenance. http://local.underhoodservice.com/BMW_Engine_Repairs_Chicago_IL-r1350256-Chicago_IL.html http://local.underhoodservice.com/BMW_Engine_Repairs_Chicago_IL-r1350256-Chicago_IL.html Searching for the diagnostic path recognizes that any diagnostic procedure is limited by time, money and the probability of success. Time, for example, is always limited by the need to make a profit at a reasonable cost to the customer. http://local.underhoodservice.com/Searching_for_the_Diagnostic_Path_Chicago_IL-r1350255-Chicago_IL.html http://local.underhoodservice.com/Searching_for_the_Diagnostic_Path_Chicago_IL-r1350255-Chicago_IL.html The factory scan tool can obviously read and access the full range of onboard diagnostics on any late-model Toyota (back to 1989), including powertrain, body, ABS and other systems. The tool also allows a technician to simultaneously view and analyze onboard vehicle data, browse relevant technical bulletins and even reprogram the vehicle from the driver's seat via the wireless TIS connection. http://local.underhoodservice.com/Diagnosing_Complex_Electronics_Systems_Chicago_IL-r1350254-Chicago_IL.html http://local.underhoodservice.com/Diagnosing_Complex_Electronics_Systems_Chicago_IL-r1350254-Chicago_IL.html There are several ways to lower the combustion chamber temps. Enrichening the fuel mixture, lowering the compression ratio, retarding the ignition timing, lowering the overall temperature of the engine, and reducing the amount of pure air can each lower the temperature in the cylinders. http://local.underhoodservice.com/EGR_Improvements_Chicago_IL-r1350253-Chicago_IL.html http://local.underhoodservice.com/EGR_Improvements_Chicago_IL-r1350253-Chicago_IL.html Once an oil leak is verified with a black light test at the head gasket joint, replacement of the head gasket can be performed. If the head was damaged by chip contamination, the head should be replaced. A revised "service-only" gasket is now released for both of these cases. http://local.underhoodservice.com/Oil_Leak_or_Oil_Weepage_Can_Result_in_Burning_Smell_Chicago_IL-r1350252-Chicago_IL.html http://local.underhoodservice.com/Oil_Leak_or_Oil_Weepage_Can_Result_in_Burning_Smell_Chicago_IL-r1350252-Chicago_IL.html To diagnose these kinds of faults, you need a scan tool or scanner software that can also display OBD II system sensor data and other operating perimeters. The more information or "PIDs" the tool can display, the better. http://local.underhoodservice.com/Scan_Tools_Software_Updates_Chicago_IL-r1350251-Chicago_IL.html http://local.underhoodservice.com/Scan_Tools_Software_Updates_Chicago_IL-r1350251-Chicago_IL.html It's important to keep in mind that all electronic vehicle components are exposed to temperature extremes and thus are vulnerable to temperature-related failures. http://local.underhoodservice.com/Temperature_Issues_Chicago_IL-r1350250-Chicago_IL.html http://local.underhoodservice.com/Temperature_Issues_Chicago_IL-r1350250-Chicago_IL.html According to the service writer, the 4Runner had spent several weeks at a shop in a neighboring community having a new timing belt and water pump installed. The neighboring shop evidently couldn’t get the engine to start, so the service writer asked if I would have time to check it out and, if possible, get their customer's vehicle on the road again. Obviously, there was more to the story than just a broken timing belt, but I, nevertheless, agreed to take on the mysterious cranking, no-start diagnostic project. http://local.underhoodservice.com/Tackling_Timing_Belts_Chicago_IL-r1350248-Chicago_IL.html http://local.underhoodservice.com/Tackling_Timing_Belts_Chicago_IL-r1350248-Chicago_IL.html The A/C compressor and power steering belt also had to be removed before the alternator drive belt could be accessed. Years of corrosion made removing the A/C compressor belt more challenging than it should have been, and an even greater array of tools was required to budge the tensioning pulley from its corroded mounting. Perhaps this example explains why many quick-service facilities give hose and belt inspection a relatively low priority on their service menus. http://local.underhoodservice.com/Belt_and_Hose_Inspections_Chicago_IL-r1350247-Chicago_IL.html http://local.underhoodservice.com/Belt_and_Hose_Inspections_Chicago_IL-r1350247-Chicago_IL.html The battery must also be capable of providing backup power for the vehicle's electrical accessories and electronic modules. When the engine is running, the charging system can usually produce enough current to meet all of the vehicle's electrical needs. http://local.underhoodservice.com/Battery_Service_Diagnosis_Chicago_IL-r1350246-Chicago_IL.html http://local.underhoodservice.com/Battery_Service_Diagnosis_Chicago_IL-r1350246-Chicago_IL.html Emergency tire inflator temporarily repairs tires safely and economically. Read on and learn more about this product. http://local.underhoodservice.com/SUPER_X_Chicago_IL-r1350245-Chicago_IL.html http://local.underhoodservice.com/SUPER_X_Chicago_IL-r1350245-Chicago_IL.html COP systems have become the hot setup for a number of packaging, performance, emissions and maintenance reasons. Placing individual ignition coils directly over each spark plug eliminates the need for long, bulky (and expensive) high voltage spark plug cables. http://local.underhoodservice.com/Understanding_Todays_Multi_Coil_Ignition_Systems_Chicago_IL-r1350243-Chicago_IL.html http://local.underhoodservice.com/Understanding_Todays_Multi_Coil_Ignition_Systems_Chicago_IL-r1350243-Chicago_IL.html Auto manufacturers are somewhat hesitant about PHEVs, saying consumers don't want to be burdened with plugging in their vehicle each night. In fact, some hybrid makers have gone out of their way to market their current gasoline/electric hybrids as "plug free." But that sentiment may be changing, especially now that gasoline has hit more than $3.50 a gallon in much of the country. http://local.underhoodservice.com/Getting_a_Charge_Out_of_New_Engine_Technology_Chicago_IL-r1350242-Chicago_IL.html http://local.underhoodservice.com/Getting_a_Charge_Out_of_New_Engine_Technology_Chicago_IL-r1350242-Chicago_IL.html Unlike any other carburetor on the market at the time, the Quadrajet nestled its float bowl between its two primary venturis so that intake air would cool the float bowl assembly. The float bowl’s fuel volume is also kept to a minimum to maximize fuel circulation through the float bowl. Both features drastically reduce fuel percolation in the float bowl when underhood temperatures reach a high extreme. http://local.underhoodservice.com/Servicing_Quadrajet_Carburetors_Chicago_IL-r1350241-Chicago_IL.html http://local.underhoodservice.com/Servicing_Quadrajet_Carburetors_Chicago_IL-r1350241-Chicago_IL.html Like the small block Chevy V8, 3800 V6 engine has undergone many changes over the years to keep it abreast of changing consumer expectations and emissions regulations. Read on to know more. http://local.underhoodservice.com/Servicing_GMs_3800_V6_Engines_Chicago_IL-r1350240-Chicago_IL.html http://local.underhoodservice.com/Servicing_GMs_3800_V6_Engines_Chicago_IL-r1350240-Chicago_IL.html Today's engines must be robust enough to withstand a hostile environment for such a long life, and without leading to gasket failure. A gasket needs to keep things such as engine oil, coolant, vacuum and combustion properly separated within an engine. In order to achieve this, gasket engineers have tried various materials to seal the engine. http://local.underhoodservice.com/The_Lowdown_on_Engine_Sealing_Chicago_IL-r1350239-Chicago_IL.html http://local.underhoodservice.com/The_Lowdown_on_Engine_Sealing_Chicago_IL-r1350239-Chicago_IL.html Cooling system failures are the number one cause of vehicle breakdowns on the highway. Many of these breakdowns are attributed to coolant leaks, water pump failures, thermostat failures and defective cooling fans. http://local.underhoodservice.com/Under_Pressure_Chicago_IL-r1350238-Chicago_IL.html http://local.underhoodservice.com/Under_Pressure_Chicago_IL-r1350238-Chicago_IL.html The operating strategy programmed into the engine computer tells the PCM how to react to various operating modes. Unfortunately for the driveability technician, the reactions of the operating strategy to various operating modes may produce data streams that don't represent reality. http://local.underhoodservice.com/Understanding_Operating_Strategies_Chicago_IL-r1350237-Chicago_IL.html http://local.underhoodservice.com/Understanding_Operating_Strategies_Chicago_IL-r1350237-Chicago_IL.html The Electronic Stability Control (ESC) program uses the Anti-Lock Brake System (ABS) and Electronic Throttle Control (ETC) to maintain vehicle stability in a cornering maneuver. The ESC program requires the communication between the Engine Control Module (ECM) and ABS controller. http://local.underhoodservice.com/Steering_Position_and_Yaw_Chicago_IL-r1350236-Chicago_IL.html http://local.underhoodservice.com/Steering_Position_and_Yaw_Chicago_IL-r1350236-Chicago_IL.html The distinctive feature of the following wheel bearings is that one of the two seals on the bearing has a built-in magnetic impulse wheel. Caution should be taken to make sure that the seal with the ABS impulse ring is installed in the correct direction. http://local.underhoodservice.com/Honda_Front_Wheel_Bearings_with_Integrated_ABS_Tone_Ring_Chicago_IL-r1350235-Chicago_IL.html http://local.underhoodservice.com/Honda_Front_Wheel_Bearings_with_Integrated_ABS_Tone_Ring_Chicago_IL-r1350235-Chicago_IL.html After much trial and error and a great amount of frustration on my part, I found that all of these failures were caused by a wire losing continuity inside the insulation or at a terminal evidently crimped over the insulation on the wire. Not that this is a common failure; as a matter of fact, it's relatively rare. In 40 years of repairing motor vehicles, I had previously encountered this condition only once or twice. http://local.underhoodservice.com/Electrical_Wiring_in_Cars_Chicago_IL-r1350234-Chicago_IL.html http://local.underhoodservice.com/Electrical_Wiring_in_Cars_Chicago_IL-r1350234-Chicago_IL.html The factory perimeter anti-theft is an extension of the remote keyless entry system. Depending on the year and model of the vehicle, the remote keyless entry system may be controlled by a dedicated Remote Anti-theft Personality module (RAP), a Body Security Module (BSM)/Central Security Module (CSM) or a Vehicle Security Module (VSM). http://local.underhoodservice.com/Gaining_Access_to_Perimeter_Anti_Theft_Systems_Chicago_IL-r1350233-Chicago_IL.html http://local.underhoodservice.com/Gaining_Access_to_Perimeter_Anti_Theft_Systems_Chicago_IL-r1350233-Chicago_IL.html Automotive lead-acid batteries must be kept at or near full charge for optimum performance and longevity. When a battery runs down or becomes fully discharged, sulfate forms on the lead plates inside the battery. Read on to have a clearer view of battery breakdown. http://local.underhoodservice.com/Battery_Breadkown_Chicago_IL-r1350231-Chicago_IL.html http://local.underhoodservice.com/Battery_Breadkown_Chicago_IL-r1350231-Chicago_IL.html BMW has used the same basic system for the last 25 years or more for regulation of interior temperature, window defrosting and ventilation. The focus of this article will be the 3 and 5 Series cars of the last 15 years, but the information on repair and diagnosis is applicable to all models. Read on to know resolutions to cooling systems. http://local.underhoodservice.com/BMW_Climate_Control_Diagnostics_Chicago_IL-r1350230-Chicago_IL.html http://local.underhoodservice.com/BMW_Climate_Control_Diagnostics_Chicago_IL-r1350230-Chicago_IL.html Whatever his name might be, most of us know that driveability techs are smart, sometimes contentious, and most often completely absorbed in what they do. In order to stay on top of their game, most spend their spare time studying the diagnostic process. http://local.underhoodservice.com/Driving_Forces_Behind_a_Driveability_Technician_Chicago_IL-r1350229-Chicago_IL.html http://local.underhoodservice.com/Driving_Forces_Behind_a_Driveability_Technician_Chicago_IL-r1350229-Chicago_IL.html The following is a recap of common A/C system problems, followed by real-life A/C system problems from 2003-’05 General Motors SUVs and a poor performing climate system on a Toyota truck. http://local.underhoodservice.com/Dos_and_Donts_in_AC_Repair_Chicago_IL-r1350228-Chicago_IL.html http://local.underhoodservice.com/Dos_and_Donts_in_AC_Repair_Chicago_IL-r1350228-Chicago_IL.html Bar’s Leaks Heavy Duty Radiator Stop Leak is the original pelletized formula that has protected hundreds of millions of vehicles worldwide since 1947. It solves most common cooling system problems, sealing internal, external and coolant-to-oil leaks in radiators, freeze plugs, gaskets, heads, blocks and heater cores. http://local.underhoodservice.com/Bars_Leaks_Original_Formula_Chicago_IL-r1350227-Chicago_IL.html http://local.underhoodservice.com/Bars_Leaks_Original_Formula_Chicago_IL-r1350227-Chicago_IL.html The opportunity for cooling system maintenance and repairs are obviously there. But many motorists never check anything under the hood until a problem occurs. Then it's often too late and the damage has already been done. http://local.underhoodservice.com/Clearing_Up_the_Cooling_System_Confusion_Chicago_IL-r1350226-Chicago_IL.html http://local.underhoodservice.com/Clearing_Up_the_Cooling_System_Confusion_Chicago_IL-r1350226-Chicago_IL.html The aftermarket has always had a knack for simplifying things the OEMs have complicated, and coolants are no exception. Coolant suppliers who have tried to meet the conflicting OEM coolant requirements now market three basics types of coolant: the traditional green formula, plus an orange formula that meets GM’s Dex-Cool 6277 specification, and a yellow hybrid (HOAT) formula for Ford, Chrysler and all the rest. http://local.underhoodservice.com/Cooling_System_Antifreeze_Requirements_Chicago_IL-r1350225-Chicago_IL.html http://local.underhoodservice.com/Cooling_System_Antifreeze_Requirements_Chicago_IL-r1350225-Chicago_IL.html
