There's actually a factory fan that can fit on the front of the radiator that I had considered installing. I have no idea of the CFM it can push, but I want the system set up to operate correctly, but you make a very valid point.
I had an electric fan on my old Chevy truck years ago and I set...
I have been debating about the CST of oil I am planning on running.
I DD my truck, so I don't really want to totally kill my gas mileage by running too heavy of CST oil, but too light and I will overheat.
Since the Kansas City area is not as hot as Dallas (usually) or as AZ or CA, then I'm...
Everything you just described is what happened with mine last week.
I just went out and checked and the new fan clutch I installed is an Aisin, blue hub (I have not modified it) and I have a new fan on there. I am going to swap out my hub and change the oil in the blue hub and modify it per...
Everything you described points to the fan clutch not working properly at idle. It needs to be engaged and pulling air when at a stop.
Also check to make sure that your radiator isn't clogged from the outside with mud, grass, whatever between the multiple coolers.
12 months ago, I was having some overheating issues pulling a small trailer. My first thought was a bad fan clutch because I could see a tiny bit of oil weep where the hub met the shaft. AFAIK, it was the original fan clutch at 285K miles.
So I bought a new hub from Amazon (Aisin) and...
If it's done incorrectly, you don't get all the bubbles out until it thermally cycles a few times. The jiggle valve allows the bubbles to weep through the system and move to the top instead of one sudden rush of a bubble that can blow off a radiator cap or a sudden massive air bubble into the...
