Sorry for being GM dumb...but what is G-05?killerbee said:Use G-05
I have tried a Ron Davis radiator , courtesy of GM, with no success in defeating the overheating. The RD rad was 1" thicker and was as big as possible.diesel71 said:were looking into differant radiators now :shrug: the local dealers act like they have never heard of this before??

Hey KB,killerbee said:... One other thing I am experimenting with: small hole in the front stat. I have not been able to prove it, but I think that area could be collecting gas (often caused by classic pump gas cavitation), inhibiting thermostat function and creating excessive latency in cycling.
