I have 4500kms on my rebuilt 308 with afr 185 heads rpm2 intake, the only coolant I use is the prestone premixed coolant.
and a bottle of redline watter wetter.
what thermostat are you using?
the hottest it gets here is 30-35 degrees celcius

i think the thermostat is 160... not for sure though... but it dont matter cuz i run 190-200F... an the rest of the stuff... celcius... you'll have to do the calculations.... [sm=alcoholic.gif]

I think 30 degrees is somewhere around 90 farenheit

I would go with the fan... as far as the rad cap, if it can handle the presure i would go for it, but only you know your car... my rad can handle the presure and it only helps prevent boil over....

silver91gt

will having a higher pressure cap decrease the temperature too?
I dont know what griffin rads are able to handle.

randy78045

Griffin rads are good.... the cap DOES NOT decrease tempature... it just prevents boil over at a higher temp.... remember science class??? Water boils at higher temp under presure.... ok... i liked science... maybe you didnt... nevertheless, the add'l presure prevents boilover at higher temps... thus, if your engine runs hotter than normal, you wont boilover.... as i said above... my engine runs at 190-200F... it should not be a problem for you either... if you dont boilover....

ok, cool
and science class was my best subject in school.
I liked chemistry best.
I just wasnt thinking.
it has been so long

silver91gt

anyways, thanks for the help

DO YOU HAVE A SHROUD?

my electric fan has one built in.
its a flexalite 220
