Re: Re: What Toyota says about v6 tranny cooler install

That is my question, do we go from the existing radiator transmission cooler to the new ext. cooler then back to the trans or do we go around the radiator? I would think you go through the existing radiator, then to the new cooler. that way the radiator still helps to cool the oil a bit before it gets to the ext. cooler and you don't need to plug anything. I plan on adding a cooler to my 96 4runner 4wd. I just bought a brand new crate motor for it and the 4runner seems to have problems towing. I was spraying oil on my last trip (300 miles) if anyone has any advice I would be greatfull.

God Bless

In another thread, Kmvreter wrote, " The stock tranny cooler is internal to the radiator. The lines are the 2 small diameter hoses going to fittings on the driver's side of the rad (next to the battery; above the large diameter lower rad hose.)"

So it looks like it does have a transmission cooler, just different from the V8 one that is outside (external) the radiator.

The members earlier in this thread say that the external one they installed does not hold much fluid, so it might not be any larger than the stock one internal to the radiator. Also, it's unclear whether they are bypassing the stock one, or adding the external transmission cooler in addtion to the stock one.

I was poking around looking at the cooler just yesterday and i saw that the V8 one has a integral cooler in the radiator (like the V6) then comes out to a external one in front of the radiator, so it pretty has dual coolers.

I was thinking of dumping the small stock one and putting in a bigger cooler thats made by Calsonic (its a Nissan 300ZX oil cooler) its a better core design made for flow and large fluid capacity. This cooler holds a additional 1qt of oil. Its about 12" wide, 10" tall, and 2.25" thick.
 
Bored. Thought I'd add a few pics of my install. I took inspiration from LV4R, thank-you.

how much hosing was used? I'm planning to pick one up from summit racing. They have many many brands for great prices!

Make sure the cooler you get is setup for 3/8" line size. Many have 5/16" fittings which will restrict flow. I chose an engine oil cooler and screwed in my own fittings.

How much line? I forget... I purchased by the foot fom a local parts store. It's cheap. Get 8 feet and you'll be fine, 5-6 is probably enough but why come up short. It's 3/8" ID hose. Get genuine transmission cooler line (not fuel line) and I highly recommend fuel injection style hose clamps. NAPA stores usually carry both.

Look at my pics to see the clamp type.

what size was your cooler? I'm about to order the B&M SuperCooler 11'' x 5-3/4'' x 3/4'' . I hope thats the right size and fitting.
 
I got it...installed it......and it's fine! Hardest part was figuring how and where you want to mount it! I also did not add any oil...or lost any oil. EASY! Should be the first mod!
 
They ALL have lines going to the side of the radiator for cooling......but ONLY the V8 had an external cooler after the radiator. The V6 didn't have the external cooler.

WTF? :confused: Mine already has one. I thought ALL 4th Gens already had intercoolers installed.

V8s have the additional auxilary cooler installed in front of the radiator. V6s do not. Both have a cooler inside the radiator. So there are two on the V8, one on the V6.
 
I bought the one that CJ3Flyr linked to and I believe boostedprozac installed.

I was just out there for a while trying to figure out how to mount it. I ended up trying to do what Chris did with 3 mount points but mine didn't line up well with the holes provided.

However, in doing so, I tried to put one of the longer bolts that came with the B&M cooler back into the bottom left mounting hole that Chris used and ended up ripping the bolt head off, pretty easily I might add.

So, I need to figure out how to get that bolt out of there now but when I do, any advice on how to install the B&M? I guess I'm looking more for boostedprozac's final setup since I have that exact same one but all advice is appreciated!

I'm going to have to cool off on mods for a little after this one, my girlfriend is getting annoyed with how much time and money I'm spending on my t4r recently.

I bought and installed the B&M Cooler that CJ3Flyr recommended as well. I installed mine in a similar place to where he installed his, but i just used some self-tapping metal screws and lock-washers and drilled through the frame in front of the radiator beneath the horn. I've had it mounted there for a couple of months now and nothing has come loose and I've had no issues.

Here are a couple of pics.

Hope this helps.

Thanks for the pics.

I took the lower grill out so the drill could fit and tried to drill and tap the bolt I ripped the head off of but it didnt work.

I gave up on that for the time being and decided to drill some holes in the cross and vertical bars for install. They were a tad bit too small for the bolts so I put on a bigger drill bit and widened them to the right size. On the LAST hole, the bit busted through with too much force and put a hole in the AC condenser

So, as I was getting the feeling of "wooo almost done!" the condenser got a hole and started spraying out fluid. It was awful, especially since its just starting to heat up and I'll need the AC soon! That and I dont think I can afford to fix it yet.

Needless to say, I'm giving up on the cooler until I fix the condenser but at least the holes are there for when I get back to it!

pull the condenser and take it to a radiator/muffler shop- they can fix it for like $50 its a easy fix and no need to replace it
 
I read on yotatech and some other forum that if you put a hole in the fins (like I did) there's nothing you can do and to seal it up until you replace the condenser. Either way, I'd love to hear your feedback but to not take this off topic, here's the link to my dedicated thread (I'll be adding a write-up when I get it done)

Replacing AC Condenser suggestions
 
So from what I have read you guys came off the bottom of the factory rad/trans cooler and went into the secondary cooler then back to trans line. Correct. So the top line going into the rad is where the hottest fluid would befor a trans temp sensor. Please correct me if I am wrong.

Thanks,
