156 2.0 T.S. - Heater Temp Control.
I have fitted a new thermostat to my 00' Reg 2.0 TS 156.
Job went quickly and well, and engine temp guage is now reading between 75 and 90 deg c as one would expect.
However I am left with one niggle ! - since replacing the thermostat I am having trouble regulating the heater temp within the cabin of the car.
With dial set at 18 deg there tends to be no heat and while set at just above that that level there appears to be full heat. Also takes a long time to get heat to start to flow in the cabin even when the eng temp guage has reached normal. Level in expansion bottle has not fluctuated since I carried out the replacement. All heater functions were normal prior to this.
Ayone have any previous of a similar problem - air lock ?? has crossed my mind .
All advice welcome
