We have a 1995 pontiac grand am. About 3 weeks ago, it started to overheat. We let it cool down and got it home. We discovered that the heater core was leaking, so we replaced it. After this replacement, the heat blows out, but does not get warm like before. The temp. Of the car gets to about 220 then drops a little. It will get higher if idling or in stop and go traffic. On the expressway, it is fine. Mecahnics have told us that there may be air in the lines and to open the coolant cap and to let it run. We have done this, but no luck. Then, they told us it may be the thermostat. We purchased one and took it to the mechanic, but he said that this was not the problem. He said that all of the hoses are warm and that it is flowing good. What do you think?
have the same problem?
