Title: Have just changed thermostat; now no heat in cabin
Post by: terry paget on 17 November 2013, 16:10:47

OE03EWW 3.2 petrol manual saloon
I have just changed the thermostat. On refilling with coolant and starting engine, there is no heat in the cabin. Have set climate controls to HI both sides, but no heat comes out. The vacuum line to HBV is still attached. Do I need to bleed something?

Yep sounds like air - engine running, heater controls set to hi, expansion cap off, burp top hose ;)

Thank you gentlemen. I discovered the top hose was cold until I burped it, then it got hot, and so did the cabin.
