Engine Cooling problem
1999 Buick Park Avenue 6 cyl Two Wheel Drive Automatic 142000 miles
Hi, I had some leaky valve cover gaskets replaced on my Ultra and in order to access the back cover, the hoses had to be disconnected to the water pump ( per mechanic) and as a result the car lost some coolant. Valve cover /gaskets replaced and filled coolant level in both radiator and reservoir with car running. After car was running at idle, temp gauge went past middle mark of 198^ and now notice it is running hotter than normal. The fans did kick on but seemed to fail to bring temp back down just below middle mark on temp gauge. Where it normally idled at. Could there be air in the lines somewhere or in the block/water pump preventing the coolant from circulating effectively, causing it to run hot? The thermostat was just changed about a month ago along with an O2 sensor. The car still has the original radiator. My concern is overheating and ruining the head gasket or cracking the block. Thanks for any help you can offer.
have the same problem?
