Anyone added an additional radiator fan?

Has anyone added an additional push fan on the front of the radiator to help cool these cars down? or is there a "super amazing" highest flow water pump?

Right now if the temp outside is 80 or above, I don't like running the AC because the temp just keeps climbing. I haven't let it go over 210, and as soon as I shut the AC off it drops back down below 200. But I would love some sort of permanent solution to the threat of overheating.


This is all with a drilled 160, zzp full aluminum oversized radiator, caspers high speed fan switch on full speed.

I don't know if the IC front mount and trans cooler just block the radiator too much or what.

210 is not hot, nore is 215. pretty normal in summer heat.

i got a load of crap blocking my rad, trans cooler, res tank, and a fmhe. i break 200 all the time, just like i did before i added all that stuff.

If you are really concerned about it, run a higher percentage of water or just straight water and rmi-25 instead of antifreeze.

You do understand these engines are designed to run hotter than 210? The radiator fans on most GM turn on in the 220-230 range unless you reprogram and lower fan on temps.
So for the record an engines is made to convert heat energy into reciprocating power. If you try to run it too cool it does several things, one it increases wear, two it decreases efficiency. Now allowing for possibly removing fan control from computer and moving to maybe a progressive controller. Something that runs slower as it cools down and speeds up. The biggest issue is why not look into different coolant. Water is corrosive alone, EG mix still causes corrosion. Try looking at Evanscooling.com. Their non aqeuous propylene glyco coolant has many advantages like zero corrosion and boiling at 375°f with zero pressure. Everyone seems to get wiggy if engines get warm, i decided to skip that and embrace the thermal efficiency. I have been tuning my race engines at much higher temps, and making better power and seeing less wear. Already went synthetic on oils so other than careful clearance adjustments and using thermal barriers coatings more its no different. An inexpensive air brush and friends who have a glass beader help.
