Not on the Escort unfortunatly But on my Cavalier 2.0 16v Red Top.

I'm not getting any heat inside the cabin And its getting chilly in the mornings now

I've flushed:

The Rad = Running clear
The Matrix = Running clear
All pipe work = Running clear
Replaced the themostate (complete with new housing)

And its still not getting hot, although there is a very slight raise in the temperature now

The cable is also fixed onto the heater slider on the dash.

If the matrix is fubar, would it not release any heat out although let water run thru it? I'm still thinking along the lines of an air lock but the dont seem to be a bleed valve on the rad anywhere

Also when i put the red top into the car, could it be that the water pipes are connected wrong?

Any help/advice would be of a great help
