Default Electric fan Q

I have a 92 f250 plow truck. It has a 5.8

Never really gets driven. And only has 40k on it.

I towed a car on my GN trailer and it started to get warm. Well.. Kinda hot. Fine at highway speeds but city is ware it was not working.

So I had this in the garage from my last build
http://m.summitracing.com/parts/sum-381010
Dual fan w/alum Shroud

And I also added an adjustable thermostat that controls them.

Now when I drive it, it will get warm and run at regular temp for about 10 min, than it will start creeping up till it over heats. If I stop and leave it running it will slowly come back down.

I had some junk in the coolant. Nasty stuff so I cleaned that all out today. I don't know what to do next. Either replace the radiator because I think it's jammed up internally from all the nasty coolant and god knows what else.

Or maby remove the Shroud And fans and go to one large single fan with no shroud?

I'm thinking its jammed full of shit or the shroud is restricting natural air flow too much. Any ideas?

Nothing good will come from removing the shroud regardless of what fan you put in there. When you remove the shroud the fan pulls air in from AROUND the radiator instead of through it. You need a shroud.

If I went to a bigger fan it would still be electric but I would mount it directly to the radiator. No shroud needed.

I think I found the problem. My thermostat. Is a push in style probe that slides in the fins of the radiator. I think that the cool air passing through by the probe is shutting the fan off because the probe is getting the wrong reading. I put a little rtv on the front of the radiator ware the probe Is to stop the air passing through and that did not help.

My thermostat has a over ride wire for AC to keep the fans on all the time. I ran that to the batt and took it for a spin and it stayed cooler than Normal temp. So that is the problem. I guess I just need to find a better probe that is in fluid to get a more accurate reading of the temp. Only thing is its a stock radiator so there is no port to thread in a probe. I'll have to research and see what I can get that works with my parts.

Drive it a bunch more today and temp stayed down with the fan on 100% of the time. Ordered a new stat that will be submerged in the coolant..

Take a look at your lower hose also. If its old and soft it will get sucked shut or sucked in enough to limit coolant flow.

The lower intake should have a pipe plug in the rear corners you could use for a temp sensor

I just replaces the stat and flushed the radiator. And yes all the fins are clear. It's working good now with the fans on 100% of the running time.
I ordered a new stat for the fans. As soon as that comes in and I make a housing for it I should be all set.
