Thread: my bbc 454's temp alright????

Tweet

225 is high, but not horrible. The second fan in my Vette is programmed at the factory to come in at 225.

What kind of fan and thermostat do you have? Do you have a radiator shroud?

Also, some Redline Water Wetter might help. It contains a surfactant that keeps the coolant from beading off of the inside of the radiator core.

As long as it's not losing water it's okay. 250 won't hurt the engine, but there's no margin for error when it's that hot.

I am running a puller fan, zirgo 4000cfm. had no room for a puller. the 454 took up ALL the room in the engine bay. the termostat is a 180, the fan come on at 185. as I said I can't run a puller fan. any other suggestion to do or try
FYI
the car is a 39 chevy coupe. with a 454, walker cobra z radiatior.
thanks forany help.
car runs fine at speed.

one more ?, is ther any high cfm fans than the zirgo 4000 cfm fan

I'm confused. You say you're running a puller fan, but you have no room for a puller fan.

should have read what I wrote............ I am running a pusher fan, I know that is not the best, but I only have a 3/4 clearence between the rad. & engine, so I puller was of the question
