How can I make my engine cooler ????

#1, if you dont already, get a good autometer temp gauge so you can see EXACTLY what the temp is, sometimes stock gauge is not very accurate.

Otherwise, I would say Fluidyne or Summit radiator, 180 tstat, good flush and fill of coolant, if its not too cold where you are at go 70/30 Water to Coolant. Some guys have good luck with the redline water wetter. Um, manual fan switch, or tweecer to override what temps the fan normally comes on. Also, in my experience, if you are running underdrive pullies, they are not helping matters any.

Get an aftermarket fan and you can set that to turn on whenever you want it to.

The larger AL radiator and a 180* stat will take care of ALL that...no need for This cooler or That cooler.

If that will take awhile, you can do a REALLY GOOD flush for now, use a 50/50 mix instead of 70/30 (that's what I use in the heat of S FL) and a bottle of watter wetter. Our cars are at the age where those radiators just arent cutting it anymore, especially when you start beefing up the engines.
