Engine Cooling problem
2003 Chevy Silverado V8 Four Wheel Drive Automatic 165000 miles
I recently replaced my head gaskets due to pressure in my cooling sytstem. However, now I have air in my cooling system which is causing my heat to come and go. I have done vacuum and pressure tests, which show that there are no leaks in the system The thermostats are opening and closing because I have flow. However, I cannot seem to find out how it is possible that air is getting into the system. I have taken off the radiator overflow cap and let the engine idle to let any air out but the problem reoccurred. After driving a little while the air block will move and I will have heat again. Then after a little the temperature gauge starts to drop and the heat goes again. Is there any way air can get into your cooling system through the water pump?
have the same problem?
