Engine Cooling problem
1998 Other Oldsmobile Models 6 cyl Front Wheel Drive Automatic 111500 miles
I have replaced the head gasket and all the other gaskets along the way with the kit I bought. I also replaced the thermostat and water pump. My car seemed to be running fine for about 3 weeks then I noticed that when I stopped at stop lights my temp would go up above the average temp. I know that this is normal but the next morning I checked my radiator and it had lost coolant. I have been adding more coolant and after I add coolant it runs fine for about 2-3 weeks then it starts to heat up at short stops. Thinking that it is an external leak I can't seem to find any signs of leaking on my drive way.
