Gets hot

[85_Ranger4x4]

I don't think a 2nd gen bumper will fit without some major fender hacking. The entire front part of the frame is different too. I don't particularly care for the looks of them either.

If I change the water pump again, we are going to a different FEAD. The stupid 9" long bolts that hold the alternator and PS pump in are extremly annoying. It is rediculous to pull the grille, fan and radiator for a mere alternator change. I have gone thru that song and dance twice now (leaking reman water pump and dying dampener pulley)... the next time I am going to fix that issue. There was an Explorer at U-Pull-It back when I was looking for some stuff for my swap that had the front clip ripped off it, waving its FEAD in my face... I have been kicking myself for not capitalizing on it everytime I have to deal with mine.

I just put the 180 stat in, last spring (cooler weather) the 195 stat did fine. My only qualm with it at the time was the fan ran all time.

Wouldn't that block a lot of the ambiant air from flowing thru the radiator at highway speeds? A puller would be different, and would act like a funnel for the fan after it went thru the radiator, but a shrouded pusher would be like using a funnel upside down.

Sorry, the fan shroud thing was a general statement. I agree, as a pusher it very well may impede flow.

I take it if you are running a pusher, you have no room for a puller?



EDIT: Does FEAD mean "front end accessory drive"?

That would certainly help if you could fit it, and I am right on what FEAD means. LOL.

Can you temporarily electrically disconnect the fan? Pull a fuse or something so it doesn't run, then drive down the highway.

I don't think the transmission coolers are causing a problem. Many cars and trucks have an A/C coil (that dissipates it's own heat into the radiator) and a transmission cooler both in front of the radiator.

Thermostat should be ok. If anything, I would change it to a 190* or 195*, in my opinion it lets the water in your radiator cool down before it comes back into the engine. When the cool water returns, the t-stat will close and allow the hot water in the radiator to cool.

2500 rpm runs the water through the radiator pretty quick too.

IDK... just some thoughts. Good luck with it.

You don't understand how a T-stat works. Once it opens, it stays open until the coolant temperature goes below the rated opening point. It does not open and close constantly while the engine is in operation. Putting in a 160* will allow the coolant to flow before it gets too hot, to the point where the radiator has a harder time cooling it. I found a 10-20* drop in going to a 160 from a 180. Normal temps ranged in the 200-210 with the 180, and dropped to 180-200 with the 160 Stat.

Yup, you got the acronym right. No room for a fan behind the radiator, I didn't move it under the support.

I started out with the "right" 195 thermostat. I went to the 180 so I would have a little more cushion and it wouldn't run the fan (with a 190 switch ) all the time. It also kinda seemed that it warmed up too fast, when the thermostat finally did open the gauge would come up and go back down after the system caught up with the heat.

Tried the highway again, it was cooler (75 degrees) and it stayed right around 190 the whole time. Didn't touch anything under the hood yet, just got the brakes done and was testing them out.
