[V6-12v] Radiator Fans not switching in correctly...

[James Whitehouse]

I don't understand - if it's holding pressure it's good? I thought it was
supposed to release pressure if it was good - although I guess it would only
release pressure when the car was overheating and the pressure went up too
high, and I don't really want to let it heat up too much! Could you clarify?

Cheers,
James
