The following cooling system components are prone to leaks: Thermostat housing gasket, water pump, heater tube o-ring at water pump housing, intake manifold gasket, and timing cover gasket. These are generally external, not internal coolant leaks so intermix with the engine oil in uncommon.

The fuse may blow repeatedly for the HVAC blower motor or the motor may stop working all together. Our technicians tell us that can often be repaired by replacing the blower motor switch with a revised switch and installing a wiring harness with a relay assembly.

Cracking or popping sounds from the cowl area may be a result of cowl cracks at the lower corners of the windshield. The fenders must be removed to see the cracks. If cracks are found, a reinforcement kit is available to correct the condition.

The engine may develop a lack of power or stalling condition due to low fuel pressure. Our technicians tell us that this can be due to contaminates passing through the fuel pick-up screen resulting in fuel pump failure. If fuel pump failure occurs it is recommend to replace the entire fuel pump module as it includes both the primary and secondary fuel pump filters.

Erratic idle conditions which can include engine stalling may occur in warm to hot weather. Our technicians tell us that a new idle air control valve is available to correct these concerns.

Under light load, at approximately 2000rpm the engine could exhibit surging, bucking, or intermittent misfires. Our technicians tell us this could be caused by a mis-indexed distributor.

The engine my develop and buck, surge, or noise due to a worn distributor drive gear. If the distributor shaft has excessive rotational free play the distributor drive gear and bushing should be replaced.

The engine may develop a rattling or lifter type noise from the timing cover area. It may also exhibit a more general valve train noise. Our technicians tell us that a revised timing chain, sprockets, and tensioner are available which may correct this concern.

Pinched or restricted transmission oil cooler lines can cause transmission failure due to lack of lubrication. Our technicians recommend complete inspection of the transmission cooler and lines if this type of failure is noted.

The manual transmission may become stuck in or blocked out of reverse or 5th gear. Our technicians tell us the repair involves replacing the transmission overdrive rail, lug shift fork, and synchronizer assembly with revised parts.

The transmission may exhibit a delayed engagement after the vehicle has been parked for an extended period. This condition can be caused by transmission fluid draining back into the transmission from the torque converter. There is a drainback relief valve available which should be installed in the transmission oil cooler pressure line to correct this issue.

A delayed transmission upshift may be noted in cold weather (32 degrees F and below). Our technicians tell us that cast iron sealing rings for the hydraulic governor are available to replace the original teflon rings to address this concern.

Excessive play cause by a bent anti-rotation bracket can cause difficulty shifting the transmission. Our technicians tell us that replacing the shift lever tower assembly may be necessary to correct this concern.
