2004 Porsche 911 ProblemsPersistent Coolant Loss Due to Small Leak at Coolant Reservoir
A small leak in the coolant reservoir can cause persistent coolant loss. To ensure engine longevity, coolant loss and overheating issues need to be resolved. Out technicians tell us the proper coolant fill procedure must be followed when refiling the cooling system.
Smoke, oil consumption, and fuel trim issues with various fault codes can be traced to an internal leak at the oil separator.
Engine oil leaks can occur at the rear main seal and/or intermediate support cover o-ring; a revised seal is available. A careful diagnosis with proper tools is necessary to verify dimensional accuracy of the crankshaft to engine block.
