i do not think you will have over heating problems,just the opposite.getting the motor to run temp.i have had two of these set ups on two diffrent motors.you want to have the engine temp around 140-165,depending on whitch type motor you have.benifets,you gane 5-10 hp.a little more room on the front of the motor,and a cleaner looking engine,simpler too.hope this helps

If you have a cerpentine belt it is a more expensive. I think it was CP performance that had one for the single belts system. If you have V belts it is much easier.

they work fine, just make sure you get one with a bypass and run the thermostat, or will run way to cold...Rob
