What did you do with your Thunderbird Today?

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.


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.
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. :P

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)

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?

Cut out and moved the dash bar down. Forget the instrument cluster not fitting because of the bar, the steering column was positioned way too high. Cut it out, places the dash and cluster in, positioned the column, repositioned the dash bar. Need to make mounts to hold the column in place now, but everything fits a lot better and I can use the OG cluster again.

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.
