Right, since the engine conversion my heating ahsnt worked, the only time it blows warm air is when the engines getting hot and starting to overheat

The overheating isnt a problem at all mind, Dazza has the same problem with his engine overheating easily cos of the conversion

Just wondered if anyone knows if I can get my normal heating system back cos its god dam baltic drivin round at the moment! lol

Cheers in advance for any help people

Sounds like your heater matrix has an airlock mate an needs bleeding, i could be wrong though so double check first.

Is it blowing? Is there no power?

its blowing, but just stone cold air until the engine starts overheating, only then does it blow hot air

thermostate could be that meesh maybe knackered and you may need to replace it and then flush your heater system out and start again with ne anti freeze also

its just my opinion

Try to get a vac bleeder , drain all your coolant then refill with the vac unit , this will ensure all the air is out of your cooling system = no air locks .
