I fitted a rear mounted Nova radiator to my Zook because the original one was knackered by someone getting in too close with a pressure washer.
The problem I have is that the Nova rad doesn't have a pressure cap and the Zooks pressure cap was on the rad. I thought that, by having the rad mounted high, I could get away without. The problem is that the engine gets up to temp, overflows the expansion tank and sucks air back into the system as it cools.
There area couple of Mini rads on eBay, at a reasonable price, so do you think one of those will do?
