Hi all

I am having a simular problem, no heat.
I have a 1995 Eagle Talon TSi.

So far the thermostat has been changed, the coolant changed and the system flushed, the heater core flushed until the water coming out is clean. Still no heat. The fan works, air comes out, but it barely warmer than the outdoor air.

My mechanic put a valve on the output hose from the heater core to check for air in the system. No air, sometimes the pressure is good (coolant sprays out if the value is opened), sometimes the pressure is low (no spray). It can change from minute to minute. Also, the coolant level at the rad cap can be up or down from minute to minute.

The mechanic has no idea what is going on and has given up.
If anyone knows what the problem is and how to get heat I would really appreciate it.

Thanks,
Brian Monk
