Chaps,
Have a very odd one, car has the thermostat in line mod.
All seems fine apart from now on two occasions it has suddenly gone from normal to red hot in around 5 seconds, pull over, fans are both running, drops back down again in says 30 seconds.
Has done this twice after being driven 35+ miles. Done about 200 miles since the mod was put in.
So today it went out with the dogs say 2 miles, sat for a bit, then 19 miles at speeds of up to 70 to town, then 2 miles around town, stopped, drove back 18 miles again high speed then suddenly shot up.
Expansion tank was clearly boiling, coolant over the engine and the level had risen to the overflow tube. Not apparent links in the coolant system hoses. When called down to gauge reading mid way normal had no fluid in expansion tank. Topped up drove back the last 2 miles with no issues at all.
Was thinking air in systems causing a block?
Or am I way of, was thinking of changing the expansion tank cap!
Open to ideas.
its a TD4 2005.
