Ok so there is the contour fans on ebay new and used they probably suck the most air .But you need a 3rd gen alt I believe? And more wireing to be done and that is allways a blast to make look clean
So what's the your guys clean set up or wire buying kit that works.

Don't skimp on the radiator. The more water that is cooled from the airflow the cooler the water will get so make sure you get a real good one with a lot of surface area and good fin spacing.

you would need zero water flow for that to be true

more water will will absorb more heat per time and will require more time to give it up

larger amount of water will not help reject more heat

GPM and CFM and coefficient of heat transfer are the key items to reject heat per time

Listen to the two gentlemen that also posted in here. Very smart guys and I always read anything they post so I can learn.
Anyways, I bought the Dorman Contour fan off of RockAuto for $90 I believe. Had it for 3 years now and not a single issue. I actually bought 2 so I could have a back up. At $90 it was a simple choice for me. You could go to a local junkyard and pull 1 or 2 from a v6 Contour or cougar. Probably be a lot cheaper, but those fans all had 150,000 miles +, so I decided on new Dorman units.

Hmmmm....searching what the Contour fan looks like showed me that is what my car had on it when I bought it. If I even need to service or replace I now know what kind of fan unit it uses.

So with that being said with the good Fans .

As for radiators, best thing I ever did to one of my cars over the year was to put a "Be Cool" radiator in it. Well worth the money!!!

Are you referring to my post? I'm talking about removing the heat from the water.

Yes i was referring to your post

Having more water just increases the amount of heat the cooling system can carry

Nothing to do with the rate at which it can absorb or reject


If your engine produces 100btus/hour

Your rad better be able to reject 100btus/hour

If it can do only 90btus/hour

Having more water in system just allows more time before an overheat happens

Does not fix the overheat

I agree. I wasn't talking about simply adding more water to the system, that's a moot point. My comment about a larger/better radiator was to address the issue you outlined above, larger as in 2-row vs 3-row, and making sure there are adequate fin density to dissipate the heat from the water and still have good airflow through it.

I believe mine is from CJ Pony. It's a 3-core aluminum for manual trans cars. I have a separate cooler/fan for the transmission located in the fender. My system works better than I ever expected.
I have a large IC from Treadstone, A/C condenser, then the radiator with factory 2002 GT fan and my car has never been 200* even in downtown traffic when temps outside were over 100*.

You can also possibly pull some heat out from the oil. Which is good for the oil and also to pull heat out a secondary way.

Your primary cooling system is the radiator/coolant system. Your secondary cooling system is your oil system, if you set it up to do so. Your tertiary cooling system is convection off the block/heads/etc...

I can't say this is definitly true, but it has been my understanding that if your engine compartment is a high pressure area, air will more around it rather than through it. Which hurts cooling performance. If it's a low pressure area, high pressure are will move through it. Which you want.

Correct. If the air inside the engine compartment (behind the radiator) isn't removed then the air being pulled in from the fan has nowhere to go so the overall airflow through the radiator is decreased. Air being pulled through the radiator has to get removed out of the engine bay to keep the air flowing.

I see, the ‘more water’ comment you made, sounded like a bigger rad that holds more water
