Thanks Steve,
I've asked my son about white smoke & he wasn't clear..... I'll ask again.
He has a basic code reader so I'll ask him to do a scan.
The only EGR-valve I've touched (Mondeo) had no cooler so I don't get how one could leak? But....
(1)Might Radweld fix it?
(2)Is the only-one-fan-turning correct for normal temp?
I mean what is the stationary off-side fan? Extreme Temp? Oil-Cooler?
Many Thanks again
