What are you using?

What are you using?![]()
I made a simple frame out of aluminum bar to mount the cooler to the rad frame and tapped into the radiator tranny lines. The oil is flowing through the cooler then the radiator for extra cooling. It is suggested to add a tranny filter in line with the tranny cooler back to the rad. I opted out of that since I don't have a race car.A couple of people mentioned oil coolers above; What you need is a transmission fluid cooler bigger is better.
It will make your trans last a lot longer. Our stock tune does the 3-4, 4-3 thing repeatedly in traffic, and the temp soars.
Tru-Cool Max. Twice the Cooling for Your Transmission. Maximum Protection for Your Vehicle. | Tru-Cool
When an auxiliary transmission oil cooler is required for your vehicle, Tru-Cool Max delivers optimal protection with double the cooling performance of our other products. Maintain lower temperatures in your transmission and lubricant with Tru-Cool and extend the life of the vehicle you depend on.www.trucool.com
I'm using the biggest one they make, 48kbtu I think.It's mounted in the front of the radiator and ac stuff. I didn't use a cold weather bypass, but depending on where you are, you may need to.
You litterly removed the skin of the seats and put them in the washing machine? I would like to add a heater to the drivers seat and thought pulling and washing would be a good time to add the heater too.
No, but I have cleaned PCV valves out before.What I did to my Cougar today (sounds like writing my weekly report to DOGE)
I contemplated replacing the PVC Valve... After watching another show about working on engines, one show and another person suggested just flushing them with engine cleaner. Thought I would give that a try instead of getting a new one for now.
Anyone else flush their PVC valve instead of replacing it?
Dang dislexia! "Yeah, what Kevin said..."No, but I have cleaned PCV valves out before.
Sometimes you can clean them, sometimes you just can't get all the crap out. I replaced one on a Subaru a week or so ago because the original valve still didn't sound very good after cleaning.

Here are the parts I used (fittings):
Parts from hardware store:
5/16" x 1/4" hose barb MIP adapter (to connect rad line to cooler hose)
1/4" x 7/8" Female pipe coupling (anything shorter won't work)
3ft of 3/8" (9.5mm) fuel line
3/4" x 1/8" x 72" rectangular aluminum bar (for mounting frame)
24 - #8 x 3/8" sheet metal screws (to mount the cooler frame to the rad frame)
4 - 1/2" copper straps (to brace the input / output fittings to the frame)
I’ve R&R’d the covers off these seats so many times but easy never comes to mind, the hog rings are always a tremendous struggle for me.
I took the seat skin off my Mark VII when I had it re-upholstered. The worse part was getting the lining hook (long plastic part that hooks under the seat) off. Interesting though, I never thought you could throw the lining into the washing machine.... "Fanstastic Baby!"Yes. They come off easily, but you have to take the seat apart to get the bottom cover off.

Adding a heater is problematic; It's a slightly different mix of foam, in a sandwich of other stuff. You'd need to get the whole sandwich, and modify our foam to accommodate it. The driver is probably pwm, with a temp sensor for feedback. But if you get all the pieces,it could be done.You litterly removed the skin of the seats and put them in the washing machine?

Seriously, do what you have read or think would be best. I do not recall where I got the layout from, but it has been there for some 17 years and no issues. In thinking about this, my thought was, send the hottest fluid through the smaller, opened radiator to cool down faster first, then into the rad where it is not cooled as fast. My two cents. Hope that helps.Ok...very useful post! But...
On my car, the top coupling on the radiator is the exit. Unless, yours is different, based on your photo, it would be: tranny > radiator > supplemental cooler > tranny. This is also the setup that is generally recommended from what I've been reading.
However, your diagram shows: tranny > supplemental cooler > radiator > tranny.

Last night, I pulled my IAC and was going to replace it with my OEM one that I pulled from the yard because I have had consistant low idle for some time now. That is one indication of a IAC going bad. After reaplacing the IAC, the car started to run like crap. I put the first IAC back in, then the car would not start. I said "F-it" and went to bed. I figured I flooded the thing. This morning, I try to start the car, no spark. Hmmm.... I put my test light on the coil to cap and got spark. I put the light to #1 plug and NO SPARK! WTF? I pull the cap off and the rotor blew up! Weirdest damg thing I have ever seen. I had a new rotor and cap (2nd pic) in my spare parts box I bought when they were on close-out at RockAuto.What I did to my Cougar today (sounds like writing my weekly report to DOGE)

Ahhhh.... now i see what you are saying. I believe you are correct. I used the top one cause I did not want to have to try and run my line under the car or radiator and if I recall, could not find an easy space to do so? I will have to look more into this and see if I have this all bass ackwards.I hear your rationale. That's a different subject.
My point was: I don't think that's what you actually did based on your photo. It shows the supplemental cooler between the radiator top coupling and the transmission. On my car, that's fluid exiting the radiator. And I can't imagine they changed that over the years; but I'm happy to be persuaded another way.
On the subject of which routing is better, i.e., which cooler should come first, the rationale I read most frequently was to go radiator > supplemental cooler. Reason being that a cooler can only cool the flow-through ATF to the temperature of the surrounding air/fluid. Assuming that the coolant in the radiator, even on the coolant exit side, is still hotter than ambient air, the radiator can cool the ATF to no lower than the coolant. Then the supplemental cooler can cool the ATF to no lower than ambient air.
(Evidently in practice, neither cooler cools the ATF that much; I'm just talking in principle.)
Some experts help me out please...
I bought a kit years and years ago and never put it in. The ad's never mention about "types of foam", they just say "put a heater in your seat and enjoy a warm arse in the winter!!!" My Town Car has them and it is a must have once you have a car that has heated (cooled) seats. I never read anything about the foam being an issue. I will look more into that if I ever do get off my arse and install it.Adding a heater is problematic; It's a slightly different mix of foam, in a sandwich of other stuff.
