Hello I have an 84 944 n/a and I haven't had it that long. It seems to me that this thing wants to overheat when I come to a stop and going down the highway when its 75 degrees out it runs on the 3/4 mark. I changed the thermostat and also changed the radiator cap and flushed the system and bled off the air but it didn't help the situation. We opened up the bleeder with the engine running to see if the water pump was pumping good and it did not spray out, the coolant just sits there and we also pulled off the heater tube and it also did not spray out. It leads me to believe that water pump is not pumping but I don't see how that can be the case when I can drive it 30 miles and it has never boiled over or anything like that. Am I thinking wrong or what do you guys think? I'm completely lost. I don't know if maybe i have to much faith in the guage and there really isn't a problem. I'm just confused why it wouldn't not spray out of the bleeder or heater tube. Thanks for your help
