A plugged heater core slowed the fluid flow to a level that seriously affected the heaters ability to provide warm air in the cabin. The entire dash, console, and steering has to be removed to R&R the heater core.
Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.
A fluid leak may develop from the propeller shaft seal on the rear of the transmission. Our technicians tell us that replacing the seal will commonly correct this concern.
