Overcooling Does Exist!

[enaberif]

You know you always hear those "stories" about people overcooling their vehicles and think to yourself nah ... no way!!! Dudes full of crap.

Let me tell you I can't be a naysayer anymore!!!!!

So I went to Canadian Tire and picked up a infrared thermometer because I was simply curious of what the temps were of things when they were running. The truck gets up to temp and I check the temp at the water pump where its entering the block...

180* F

So then I put the gun on the base of the waterneck..

170* F

I am showing a 10 degree difference between the water neck and the water pump... So I check the temp of the radiator ... 41* F. Hmmmm I go this can't be right can it?

So go into the shop grab a couple of tools and pull the fan off the truck and run straight pulley no fan. Start the truck again and let get running and now I put my gun on the water pump at the head again..

190* F

I jumped 10 degrees by removing the fan!! I'm thinking hmm really? So I let the truck run some more and then I check the pump at the head..

205* F

Well now I'm shocked! So I put the gun at the base of the water neck..

195* F

Look into the radiator and the coolant is bubbling and I can actually see the coolant flowing like its supposed!!! Succcesss!! Water pump is pumping.. thermostat is opening.

So guys.... Yes you can simply overcool your vehicle based off the fan you are running!!!

So this weekend off to PnP to pick up a clutch fan.
