Average Mileage: 140,001 mi (13,241 mi - 970,000 mi)

Verified

The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.

    The crossovers began leaking coolant. When this happens the coolant may mix with dirt from the engine or ground and appear to be oil. Heritage Cadillac robbed me of $1,500 by replacing the head gasket, knowing the crossover gasket was defective. Eventually, Heritage Cadillac replaced the crossover and water pump for another $1,500, only to say my electronic shocks were going bad. It's been a year later and my shocks are fine.
    That Heritage Caddillac of JONESBORO, GA. Go to PEP BOYS, they won't cheat, lie, and overprice you.

    Radiator has been replaced once already at 70000 miles. The leaks persist but are not severe, yet. Average is perhaps 1/2 gallon per month/200 miles of travel.
