Diff Coolers

[matcop]

Need help with a diff cooler. Anyone running a diff cooler in So CA. Price and what company did the work and what type of diff cooler.

I had tried to order the GTM diff cooler with the switch but as everyone knows, GTM is in the business of showing nice and pretty parts but never producing what they advertise (at least from my experience !)

Any help would be much appreciated

I was told the GTR one would work but Im not about to pay GTR prices.

Please let me know how it works out for you guys. Im sure Ill see you guys at the track. Looking forward to the cooler track days.

Just make your own. Use the tilton 40-524 or 40-525, a 12 row cooler if its great or 24 row if not as good of a design, 6 feet of SS hose, fittings, and oil filter before the pump. I have just under $500 in mine. Screw GTMs $1300 asking for the same ****.

If you want ill post where to buy and exact part numbers you'll need.

ive heard of some reliability issues with the tilton pump, i was going to use the Setrab one

You're going to hear stuff about everything. Just googled and found guys running them 4 years plus without issue.

well i heard it from close friends who used them or racing, and have been told more positive things about the Setrab unit, anyone can feel free to use the tilton pump, just saying im not

The -8 to 18mm x 1.50 goes into the diff drain and fill holes.

Off the bottom drain hole goes the -8 to hose 45*. That will have hose that bends 45* also to go straight up and go through the trunk floor through a rubber grommet. Then 90* back to the diff pump at the rear of the trunk.

The hose then goes into the -8 hose straight.

Which then attaches to the inline filter.

Then a female to female -8 straight to attach the filter to the 3/8 to -8 nipple going into the pump.

Then of course the pump which the other side will have the other 3/8 to -8 nipple.

Off that the 3/8 nipple attaches to a 90* AN female to female which attaches to the 1/2 to -8 nipple going into the cooler.

Other side going back now has the other 1/2 to -8 nipple in the cooler and attaches to the -8 to hose 90*. That hose now does the same thing and runs down the trunk inside then 90* through the floor.

The hose then attaches to the other -8 to hose 90* which attaches to the other -8 to 18mm x 1.50.

All this can be bought at summit racing. You might find cheaper prices but summit does free shipping and every order they send a $20 off your next $100 plus order. If you buy all this $100 at a time you get $20 off every $100 order! Its hard to beat up to $60 off everything.

Pics incase anyone got confused...



The gap on the lower hose is where the diff pump sits in between the two 3/8 to -8 nipples



The -8 to 18mm x 1.50 fitting to -8 to hose 45*



Only the cooler is on outside of the car. I'll be making a aluminium scoop for the cooler to sit in and catch air under the car.



This is where the 90's in the first pic attach to the 1/2 to -8 nipples in the cooler.

Well for double the price, 3 need to break on me before I spend more than the Setrab. Not to mention the warranty on every pump, so for several years I'm sure it will be fine as others again have had no issue.

I've seen several cars on fire this year from engine oil etc and how hard those fluid fires are to put out, I would stay away from running the pump and lines inside the trunk.

Well I wouldn't be worried about diff oil on fire for how thick it is and not like engine oil, and the tail pipes aren't hot enough like a header is. Burns are a concern though. I can always do an enclosed box to catch spray.

I mean if guys running fuel cells with fuel hose in the back do that, I shouldn't be that worried about 75w90 diff oil that's not as volatile.
