A12 overheating
Posted: Mon Sep 24, 2012 9:04 am
Right, I have one a12 engine which like to get very hot very quickly.
Water use is minimal (in the time it takes to get hot (as in stop diring its too hot hot) which is say 10mins of driving, will happily idle at halfway on the gauge for ever and ever and not use water).
Radiator has been flushed (with a hose haha) and returned all matter of brown particles and crud.
When reved with the cap off water appears to be moving around suggesting the water pump is working (in one way or another).
No change in behavoiur with or without a thermostat (which was opening and closing as expected).
Suggestions? Ideas?
Can radiators be tested? or not worth the effort? Should I whip the waterpump off and see what it looks like? Is it a possible BHG? Havnt dropped sump/oil but dipstick shows no water, and there is no visible evidence of oil in the water.
