I finally had a day off with 'proper' weather to be able to install my radiator. Following NikFu's excellent write up, I found the hardest part was removing the darn blue plastic covers they used to seal up all of the orifices!
My RotoZip made quick work of the required fan mods.
My upper mounts lined up much better than NikFu's did, I was able to get all four bolts in with no problems. The supplied 16lb 'Stant' style octagonal radiator cap works just fine with the red lock lever pointing straight towards the overflow nipple. The only thing I still need to deal with is the mismatch from the overflow nipple to the stock overflow tube.
On my test drive, it took a couple of extra miles for the TC to lock up. Considering that the air temp was 50-52 degrees today vs. my recent drives at 35-40 degrees on the same route, I'd have to say the extra transmission cooling is really working! Unfortunately, I don't have a tranny temp gauge to be able to prove anything.
One other thing of note, my water temp gauge has always stayed level once it got up to temp, never budging no matter what type of driving (powering uphill or coasting downhill). After things were tested to be leak-free, I played around some. I 'stomped on it' up a slight hill, 5500-6000 RPM for about 15-20 seconds . . . the water temp gauge dropped! When I slowed back down so the cruise control could re-engage at 60 MPH, the TC didn't immediately lock like it normally did . . . was the tranny fluid too cool?
Right now I'm just running water, next week I'll get proper coolant back into her and see if anything changes.
