Looking for opinions on the best options for keeping engine operating temps. as low as possible.(for insane 110+ driving conditions here in AZ.) I am looking at the Mugen thermostat + fan switch, with a radiator plate. Looking for a larger capacity radiator or higher CFM radiator fan at a resonable price. Also, would there be any benefit to doing the TB coolant bypass mod (i.e 3/8'' ball bearings)as far as lowering the coolant temp.? Any ideas/help welcome and appreciated.

ps. I am asking the question because, I am running the coastal metals front grill and have only seen over three bars one time(went to four for a second then back to three.)but, it has me worried it may be running borderline three/four bars all the time. In AZ , the cooler...the better.

 

do what i did, move!! Everday is perfect, never gets above 85 , nor below 75.

make sure the top is treated for UV protection if it sees sunlite.

 

Spoon or Mugen thermostat, thermoswitch, and radiator cap are great starts. Also consider the Ztec/Spugen heat shield and a radiator cover (to force more air through the radiator).
I have a Coastal Metals front grill as well, but what does it have to do with cooling and engine bay temps?

some of the forced induction guys use them.

 

I think the best mod is the hondata intake mani gasket. It does make a big difference, and you can tell once it's on that it eliminates most if not all bogging that accures. The mugen mods would be good aswell along wih a radiator. Other then those suggestions I am not sure.

 

btw, 4 bars is not overheating by any means.
