All help appreciated TIA You may need to bleed air out of the cooling system. There is a method buried somewhere in this forum. Or possibly the heater flap valve is faulty, again covered n the forum. Is your thermostat stuck open ? Quote Link to comment Share on other sites More sharing options...

Notabongo Posted 12 hours ago Author Share Posted 12 hours ago No real pressure in the coolant system can open rad cap after a run and no bubbling or excessively hot so don't know if thats another issue or connected Quote Link to comment Share on other sites More sharing options...
