Ya, nope, they are not spring loaded. The fittings in yours don't look like they would work at all. They are filthy. Never gong to get all the crap cleaned out of there.

Why would Ford install a cooler in the rad, and just not hook it up?





Edit: I could have swore his post right b4 mine was different yesterday.....

I would guess that wasn't the original radiator. I don't even know if you can buy a replacement 99/03 radiator without the cooler. My early build 2000 didn't have the OTW transmission cooler from the factory and I had to buy a new radiator to get one.

New radiator is right at $200 usd.

Late 99 F250 did not come with transmission lines hooked to the radiator. I am guessing when the rad and the original transmission got replaced, they left the set up the same.. Yeah I know dumb. I am going to see if I can take off those connections and sand blast them.

Went to Ford dealer, my friend hooked up his laptop with the ford software no communication issues. while Idling the Proshift guage was reading 129 degrees, his laptop read 129 degrees so the gauge is dead on. Found 2 codes P0541 Manifold intake air heater circuit low (I did an IAH delete.. has to be a soft code not throwing ses), and P1280 Injector Pressure (ICP) circuit out of range; that's interesting because the ICP sensor is brand new just replaced it and the harness... I swore I wired the new pig tail correct. Does anyone have a pic of their ICP sensor with the colors of the wires showing? I want to confirm I wired it right

The 1280 could have been an old code from before you replaced the sensor. If you arn't getting a CEL now I wouldn't worry about it.

It can also be caused by a tuner.

CEL is on currently cleared all codes those two poped right up, no tuner/chip ever installed.

I tried to get a shot of my ICP sensor but all the wires are black. I'm afraid to clean or mess with them to much, with 485k on the odometer they have been through a few heat cycles.

Try posting down in the 99-03 7.3 section, someone will have a picture and/or schematics with wire color handy.

Thanks for the effort! I hope the below pic will help when i look at the wires. (NOT MY TRUCK)

If it helps, I have a 2000 F-350 without the radiator cooling and the 6.0 cooler upgrade. On an 85 degree day at 60, I rarely touch 140 on my transmission if I am empty. I never see 200 unless I am towing and never see over 220.

Did you hook it up to the computer to get the computer reading of the transmission temp to verify your sensors accuracy?

Not sure if this would help you, but I used one of these in a 1997 F Super Duty 7.3. It helped greatly at a price that didn't break the bank.

I recently added the newer radiator and lines yo my 99 V10 part numbers are in my thread linked below. :-X22

I took off the tranny line connections at the bottom of my radiator and welded 38"s barb connections to them. I hooked up the tranny lines to the radiator then they go to the 6.0 cooler now. Took a pic of the fabricated connection below

-- Hooked up tranny cooler lines to radiator (truck now has rad as a cooler and 6.0 as a cooler) it was 93 degrees out I traveled 65mph down the high way 10 miles, the tranny temp hit 188 degrees, which is higher than others who tow 10k or more with less mods. Something isn't right.. the last thing that is suspect is maybe the torque converter? Maybe I can take it to a transmission shop and have them activate the torque converter while parked some how?

I have the Rad cooler and 6.0 cooler, towing with CGVW was over 30,000 lbs, hottest I saw was 200.

Just the pickup alone on 95* weather it hits about 160*

On a side note, I saw lower temps in OD than in D at the same speeds.

Yeah... something isnt right with my transmission.

Maybe the lockup isn't working on the torque converter
