Cooling system upgrades?

[Dan Gray]

The old stang runs a little hot when driving her hard. I do have an aluminum rad and high flow electric fan(3300cfm). But i was wondering if anyone has tried an aluminum high flow waterpump like edelbrock. Or what about an electric waterpump? I do run power pulleys so the waterpump is running slower but im wondering if its worth the money to upgrade to the next level of waterpumps.....

Opinions please........

Thanks
Dan

sorry i dont have any experience with anything other than stock water pumps

what kind of radiator is this that you have? also is it still in good condition?

on a side note, i was having the same high temp issues as you. i was using the stock pump, underdrive pulleys, black tragic fan, and the stock radiator. from there all i did was replace my old stock radiator with an Afco aluminum and my temps are now in check. even in stop and go traffic. well these are my experiences, hope this helps.

oh and BTW this is on a 300-350 hp engine.

sounds like its cuz of the stroke... they present cooling issues if i recall dont they?

dont know about high flo water pumps, sorry, just searching for a cause of the overheat

Its a griffin aluminum rad. I just installed it and the temps are already way better but i would like to see them a little lower. I do have a 160 thermostat and the temp run around the 180 range all the time and as high at 210 when driving her hard. Im going to look further into airflow across the rad and go from there.....

I have a 331 and can't get the temp past the 1/2 way mark - I run a Taurus fan, Griffen rad, Stewart Components water pump and a DC Controller - what do you use to control the fan?

I don't think that running at 210 is necessarily bad, assuming the motor is in good condition. The stock stat is about 195F, so your not far off from that.

What would concern me is that you are getting 30F over your stat temp. This could suggest that there is a deficiency in the system.

Still, does the temp jump up and then drop down fairly quickly at a predictable rate? If so this is fairly normal, when driving hard for short periods.

Something else to check (in addition to everything mentioned above) is the height of the radiator overflow. The overflow nipple should be the highest spot in the cooling system. Somtimes when radiators are replaced the rubber mounts on the bottom of the rad are tossed. This can cause problems.
