As far as the fan goes, stock shroud/fan and a severe duty clutch.

 

We are coming from Cincy, Ohio to Niagara falls campground and lodging on Niagara falls rd.

 

Maybe the water pump or a stat that's stuck closed. I changed my water pump a few months ago, it was leaking out the weep hole, I got a 360 too and I had heat issues and I'll tell ya the leak was hard to spot.

Get a flash light and an inspection mirror. Get underneath her and possiton yourself under the crankshaft pulley. It will look like a leaking timing cover shaft seal, however if you follow the leak to the top of the crankshaft pulley you'll see what looks like coolant leaking from where the bottom hose connects to the water pump, in my case what was happening was the water pump was leaking from the weep hole and the coolant was being sprayed onto these parts while driving making it difficult to find the source of the leak this is because the weep hole is on thetop side of the pump.

I hope you have a stat and not a pump problem, the pump is about $60, but is kinda a sucky job to do.

 

Pump is less than a year old. I didn't think changing it was that bad though. Maybe it was cause it was the day after the starter swap, which was a royal Pain in the ****...

I'm gona change the stat though. The truck cools fine when not towing, I want it to cool the same way when under load.

 

OIC. The stock electric fan isn't going to cut it. In this thread about replacing for the HiPo Ford fan or a Viper fan. I couldn't tell if you upgraded to one and were having issues or not.

If you want to run electric only, get the Mark VIII. You are wasting your time on trying to get the stocker electric fan to cool the D in anything but optimal conditions.

Indy,

My D is a 99...1 clutch fan for all the cooling needs. No stock elec.

All of my elec fan problems are with a Mark Viii Fan.

 

Cess,

You mentioned that you may have lost one of the speeds on the fan? You can check by testing each of the wires separately and find out which wire is high, low. Hopefully both speeds still work. Have you connected both wires together or somehow wired the fan where it may accidentally send power to both speeds at the same time? If have you know which is high speed, ONLY use that one, just tape off the low speed wire and not use it.

 

An electrical guy at work tested it. He said only one speed is working. Other than that, I don't know which wire is high through testing, though I was told low is the middle wire. If that's the case, then low isn't working. But if low isn't working, will that affect how high works?

 

I don't understand how a fan control is a waste of money? You can program it to turn on at any temp. And a 3300 CFM fan with shroud is more than enough to cool down a stock 5.2/5.9. This is the one I use.

Becasue that is $115 to do what a $6 switch and 2 $8 relays can do......
