After reading this I am wondering if I should use the stock tranny cooler then use the B&M external cooler as well that I am currently running? Currently I am only using the external as I installed it with I had about 150k miles on my original radiator(which I am still using currently). But also got a new denso radiator to install waiting in the garage. My plan was to use the new radiator with bypassing the radiator cooler and just use the external I currently because its already installed. So should I go back to the original cooler now or use both at the same time? If it matters, I live in southern California so the temps here are always pretty good and I don't tow with it as its just my daily driver when driving my kids around town, occasionally drive to the mountains/camping/etc. Any help/opinions guys? Thanks.

Not trying to hijack this thread, and maybe it could help the other guys, but I have a B&M Cooler questions.
Since I just redid my radiator and ran them in series (Radiator Cooler first, then B&M) to clean up the routing of the hoses (and removed several feet) I flipped my B&M so the hoses enter and leave from the bottom.
I've ran it in the past where the inlet and outlet were on the side or the top (which due to gravity I know it would fill up the cooler).
But if they are on the bottom, like they are now... is it designed to fill up the cooler before leaving or is the fluid now just going in the cooler, maybe filling the lower 1/3rd of it and leaving?
I took the truck out camping and my gauges still says it's functional, but I want to make sure it's 100% functional. I really like how the install is, and how the hoses are routed, but if it's not filling completely then it's kind of a waste.

It's fine, that's exactly how I and many others have installed their aux coolers
The pump in the transmission will fill the aux cooler, and if you have a low-temp bypass aux cooler, typically based on fluid viscosity, the aux cooler won't fill till the fluid is hot enough and the fluid will just exit the aux cooler.
All good

Cool thanks! My first B&M didn't have the bypass in it, then I learned about it and I bought the one that did. Though I wish they would stamp the model number on them, because I looked to see which one I had when I was redoing everything.... :thanks:

Unfortunately the radiator from Camelback is the same Taiwanese Denso radiator Amazon sells. But at least it was packaged well .

I would like to know this as well . It would be nice to have the rad not hanging so low. Maybe something from a Tacoma ?

I got a hayden from amazon for 30 bucks. It included hoses and clamps and mounting straps. super easy and well packaged. It is smaller than i expected, but running along with the new radiator, itll be fine. I'll get you a part number

BTW, Freeman Toyota here in DFW (Hurst) had radiators for $111 bucks. They are cheaper than Camelback on a lot of their stuff. Just a heads up! Amazon was $121...

What B&M cooler are you running? My Hayden has metal tubing running through it, which is where the fluid runs, so it HAS to flow through the whole thing. Im curious to see your B&M.

This is the hayden cooler i bought. Hoses running down, fits great. I do wish it was bigger but this (with radiator cooler) is better than not having one at all.

See Post #25 in here... I don't remember off hand, but it's the popular one everyone gets on here. Search for B&M in the search on here and I bet it would pop up.

Realistically any cooler that fits, and has a low-temp bypass, will work
I used TruCool, [MENTION=143526]theesotericone[/MENTION] used Hayden, most other use B$M which is the most expensive
The biggest decision to make when purchasing the cooler is whether you will install an electric fan on the aux cooler to help with low RPM cooling while wheeling. If yes, then make sure your cooler is large enough to fit the fan, and then the mounting brackets will need to support both. If I were to do it again I'd do it the way [MENTION=143526]theesotericone[/MENTION] did it on the driver side with an e-fan for a wheeling-specific rig.
If you are going to secure the aux cooler to AC condenser core using the zip type mounts included it will be easier to do if you remove the radiator; doing this when replacing the radiator is ideal. Removing the front bumper will help too. Personally, I would not secure both aux cooler and aux cooler e-fan to the condenser core alone.

LOL. I was going to edit my post and add that i DID install with radiator OUT. It is between the radiator and condenser and would be a total pain installing without taking the radiator out....

As did I when I first installed mine. I had around 150-160K miles on it and bypassed just for a piece of mind.
When I put my Champion in, I'm now using it along with my Aux. Cooler (with a fan behind it).
Boils down to do what lets you sleep at night. If you have an old radiator, do what your gut tells you. If you have a new radiator, use it like it's designed to be used.
