LOL. That's the fan.
I don't recall the depth but it does fit. Here's the only shot I took while I was doing the install.
If you go with the same fan there's one thing you need to do. You have to convert it from a pull fan to a push fan. From the factory it's set to pull air from the rear and pass it to the front. You'll want it set to push air from the front to the rear. It takes less then 5 minutes to do.
Undo the nut that holds the fan to the shaft. Pull the fan off. Flip the fan over. Put the fan back on. Re-install the nut. When you wire it wire it in reverse. Positive to neg and neg to pos. That will spin the motor backwards, which causes no harm to electric motors, and just like that you now have a push fan.
Some good deduction I suppose (finding your fan).
For this application, I like that you are pushing with the fan. I've flipped a prop before so I follow you. Nice job Matt.
I think this is the first tranny cooler I've seen mounted on the driver side. Curious as to why that location. Maybe has to do with other stuff you have installed. Looks like you have an Engo winch, as I see the box there...
I've had oil and tranny coolers in other locations too, not just stacked behind the grille. I'm curious if there might be another spot for us with decent air flow and safe from impact. To Mike's point earlier that I have yet to respond (sorry), adding more volume or capacity often makes for improvements alright. I've seen this no matter the fluid. That said, if that fluid manages to get too hot, it can take much longer to cool down...
I'm not under my truck now, but I'm pondering the feasibility of a rear mounted tranny cooler. A simple funnel or ducting system, if there is space for such, would ensure it gets sufficient airflow. Still have a fan of course, on the back pulling... I've done fans within ducting before too, as another possibility. Due to the lengths of plumbing involved, there would be increased volume too.
If this looks to be desirable, it would also be a win because there would be less stacking of heat exchangers up front which makes for degradation, the radiator taking the brunt of it (hotter than ambient acting as the cooling agent)...
Since our rigs are 20 years old, I imagine someone has already done this or figured-out it's not beneficial. I'll do some searching...
Matt, did you upgrade your alternator, CS144 or other? Running a winch, a fan, and other items, I'm guessing you might have.
