RepairPal has identified the most common problems for 76 Chevrolet models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Vehicles with a V6 engine may develop an oil leak from the front crankshaft seal. Our technicians tell us a revised front crankshaft seal is available to correct this concern.
The turn signal switch may fail causing the hazard/turn signal flasher to continue to click even when the turn signal switch is off. Replacing the faulty turn signal switch will commonly correct this condition.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
Various issues with the electric power steering system may develop and could require replacement of steering column assembly.
The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.
The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.
A rattle-type noise may be noted on cold start-up due to a failing timing chain tensioner. Chevrolet revised the design of the tensioner multiple times over the production of the Cobalt, replacement is necessary to remedy this condition. A failed chain tensioner may result in a broken timing chain and subsequent engine damage if the issue is not diagnosed and repaired.
The cooling fan clutch may fail causing excessive fan noise and/or the Check Engine Light to illuminate.
The serpentine belt tensioner can fail; it may become noisy and/or the belt may jump off. Replacement of the failed tensioner will be necessary.
The throttle body gasket may develop a vacuum leak which may result in a higher than normal engine idle. Failed gaskets will require replacement.
The 2004-2007 Chevrolet Silverado 2500HD has known issues with the EVAP system, a part of your emission control system.
To correct the issue, the EVAP canister vent valve, solenoid, and wiring must be inspected. The most common fix is replacement of the wiring connector or replacement of the vent valve assembly.
