[quote=”nightflyr” post=204300]Has anyone done a combustion gas test?
if there is – A small leak in the lower driver side of the radiator is noted, perhaps 2 ml per hour of hard driving.
This doesn’t show up in a pressure or vacuum test.
If coolant can leak out air can leak in.[/quote]
That is what I thought. Mechanic seems to think it would suck back from the reservoir before coming in through that small leak (pin hole?).
I should add, I did replace rad cap and that also made no difference.
