pinky Posted September 10, 2012 Report Share Posted September 10, 2012 hi Paul i had this over heating problem, it is a air lock in the head i drilled and taped the thermostat cover 5mm screw with a fiber washer on it heat the engine up and then open the screw (wearing a glove) the air comes out like a pressure cooker quick and clean pink Quote Link to post Share on other sites
Andy Moltu Posted September 10, 2012 Report Share Posted September 10, 2012 Pinky - I suspect you are creating a solution to a problem that doesn't really exist. The water pump is low enough that any air in the block will blow into the rad and self bleed. If a small amout of air remains in the cooling system it should significantly affect the running temp.

Correct There is not and never will be a need to vent the stat housing Quote Link to post Share on other sites
Peter Cobbold Posted September 10, 2012 Report Share Posted September 10, 2012 The rad on my 6 is tilted forwards so the filler is an inch or two lower than standard. No problems with air locking despite that and longer top hose. Cooling is fine, manual electric fan. Quote Link to post Share on other sites

Mark V Posted September 11, 2012 Report Share Posted September 11, 2012 With regard to the hot running I would reccomend checking the rad. My car ran hot and the root cause after much messing about was that the rad was a 3 row version instead of 4 row. easy to see the difference when you look through the core as 3 row shows much more daylight or count the rows!
