Three problems related to engine cooling system have been reported for the 1997 Buick Park Avenue. The most recently reported issues are listed below.
After 20 miles of smooth driving with no indication of anything going wrong and while pulling into the parking lot of my office my check engine light came on, I always immediately shutoff my vehicle any time such thing happens to prevent any damage to the vehicle, I proceeded to walk into the parts store next to my office to get power steering fluid due to the low fluid level I had, however when I tried to turn over the motor the motor would not turn. My mechanic told me it was "hydrolocked" and that there is a coolant passage which is commonly known to leak into cylinder 6 and locking the motor requiring the intake and gaskets to be replaced. This happened less than 30days after my vehicle passed inspection at a dealership. Also noting that the dealer was told I was losing about a gallon of coolant weekly. A coolant elbow was repaired, then two days later is when the motor locked.
No engine failure yet. . . . I am consuming almost as much antifreeze as I am gasoline. Just kidding, but in less than 1000 miles I have used 11/2 gallons of dexcool antifreeze. I can find no leakage on my garage floor, but it sure is going somewhere. Am I in eminent danger of engine failure?????.
Engine burned out because there was no coolant in system. Also talked to mechanics, and mechanics stated plenium which was part of coolant system, cracked causing coolant escape and burned engine out. There be no coolant in engine.
