Yes, the 203* T was a boom like the ICP mod several years was. Im going to go to the 180* or 190 or 192* IIRC (the one I pulled out) thermostat. Do you know if the IH thermostat is 180*. I have a IH dealer in the nearby.
The link is for the coolant filter, I asked for the Billet Housing and the new RADIATOR HOSE # parts, that has to be used with that new billet housing, that is different from the OBS. thanks anyway.

Byron Im in the same channel about the high temps.

 

On my way home from RRE, I hit the "L" on the gauge and oil temp was up to 250. I pulled over and it immediately started dropping, then I went on. But I've got bigger fish frying, I don't have any go fast goodies besides DP, chip, and intake.

I don't think oil temp is a huge deal on these, but obviously water temp not far behind would be.

 

I like my 203° thermostat. I've never had issues with it getting too hot, but I think you guys are working your trucks a lot harder than I do. I would be more comfortable with a numerical gauge...

 

Yeah Thomas, I talked with Clay at length about this whole temp thing. He said it won't really hurt anything other than shortening oil life. I was glad to hear that since I got mine up to 235-240 with the Napa 192 thermostat. With the 180 though, EOTs were never higher than 220 towing and that was really working it. I just wanted to see how it would behave and it was good.

Glenn, don't pull yours. There is no way to seal it. The gasket depends on the Tstat to seal. I tried this too....no Bueno.

 

At what temp does the 180 start to open?

 

Curious what Glenn comes up with here. I did not have a monitor on the truck to see EOT. but I had the same issue this past weekend when towing a few passes. There is something else going on. Usually when pump starts failing this is what I would expect, but I put in a brand new Alliant Power OE pump and FORD thermostat. I rarely see it too but I am starting to think my radiator is truly plugged up a bit or my coolant temp sensor is reading funny. I do not believe it’s the coolant temp sensor though as when I’m driving unloaded I’m anywhere between the N and R like it typically was. The truck always was at or a tad below N when cruising unloaded.

This weekend we pulled a couple 8-15 miles passes with the pedal to the floor in 4th/5th and the truck would steadily climb all the way to the L and seemed like it might have kept going. Def felt hot in the cab too. It never did this before. Would never climb over M. I only had about 8k behind the truck and have pulled 3 times that up much steeper grades in 2nd or 3rd gear only without it ever going over M. Going down the backside it would cool right back down, but just didn’t seem like it was cooling as efficiently as it had in the past. So besides a lower temp thermo, and or a new radiator. I’m not sure what else it could be.

I'm really curious what glen comes up with, as I was able to hit L on the gauge, and I do not want to do that again either. I know my oil was hot because I had a bit of spatter from my CCV on the trailer. Even when I towed heavy I never saw that.

So Glenn.... I am really curious to hear what you find out! Because I will be following suit!

 

I never noticed that you said the gauge was in the middle. Maybe that light is your problem, and there really isn't one. I wish you had all your gauges in, like I'm sure you do too!

 

Good to hear Byron but I would think that the Ford gray stuff would seal it? If not, a guy could gut the thermostat and just have the ring on top to help seal it. This would be my last, last resort.


I'm still going to order that 180°!


Darin, you might be right about the light and that's what I thought yesterday, I kept going. The gauge in the middle isn't to bad, higher then I've seen before on my other PSD's. Like Nike said, downhills it would cool right off and when it wanted to go above the middle of the gauge I could hear the roar of the clutch fan. But, when I got here and let it idle while I opened gates it didn't cool off, that bothers me! Of course there isn't any air movement doing that but it was in the mid 50°'s.

 

I just read Nike's thread and I had a thought. Nothing was different except new WP and thermostat-both Ford. The difference is I added a filter and didn't fill it before installing it. Surely that wouldn't create a 'air pocket' and cause problems, would it??

 

Glenn, hate to even ask but are you sure the thermostat Ford gave you is the long stem version? If not it could account for the overheating. Here is a picture of my long stem stat before installing it ...

 

I'll refer to your picture when I pull it out Jim but I got it from a Ford dealer and I told the parts guy what truck I have. I used a short stem one in my IH pump so I'm pretty sure I got the right one for my Ford WP. Thanks

 

Glenn, you may want to pick up a 5/16 fine threaded lock nut for that dp clamp too. Means yours was trashed, and all I had was 2 regular nuts to put on, I'd feel better if you'd put a locknut on the outside of the first nut.

 

OK, sounds good Darin!

 

Got a part number because I still have my box and did not measure before I put it in. But I made sure it was for a 96/97 and not a 95 short stem...never measured.... though

 

The differences are at simple saight (spl?).
