DIY Differential Cooler Installed

[PBBLASTER]

I went my own way on the design and installation of a diff cooler. The pump and fan are standard fare from Summit Racing but the plumbing and wiring are unique. I wanted simple and effective. I placed the thermostat switch as close to the diff as possible. Most of the brass fittings were from Amazon. I'll start with link and upload more pics as I get time.

Some random images: The first image shows a tube splice union. That is where I will disconnect add a hose and use the pump to fill the differential from a jug. The thermostat switch bushing is how I will drain the fluid. I used a split nylon tube to cover the sharp edge of the bracket. I used fiberglass to insulate the brass adapter to reduce false low temperatures. all the brass, thermostat switch and relay came from Amazon.

Very cool, I hope this proves to be reliable for you.

Cool project. Is there a reason you decided pull the hot fluid thru the pump before the radiator? It may be better for the pump to pull it through the radiator first, so it doesn’t see hot fluid.

Great question. I had it the other way around at first and if you look closely at the pics you may see that. When I went to use the pump to fill the diff with fluid it was surprisingly slow. It took abut 45 seconds to move 1 quart. That pump is supposed to move 4- 8 quarts a minute. It is clearly design to push rather than pull so I switched it back. The pump is temperature rated 0-256F. The thermostat switch is set to 185F. Between that and the couple feet of tubing from diff to pump it should have plenty of safety margin to over-temp condition.

Just found and ordered the steeda Differential Cooler from tps motorsports, not sure if it’s a screw up, but it was only $169.96. I’ll update to let you know if it arrives

Any update on this? They still had it for sale so I pulled the trigger on it as well.

I got impatient, after a month of waiting, tps motor sports said steeda did not have the kit in stock so I cancelled the order and built a custom setup. I probably should have waited for thwm to cancel the order. Hopefully they ship it to you for the price that is advertised.

That's...unfortunate. I'll hold out for a while. I could probably build a DH setup if needed, but it would definitely cost the same as the Steeda one. Did you end up documenting your setup?

the cost was about the same, I bought all of the rear valance parts too. I didn’t document it, but I can snap some pictures of the installation. If I could do it all over again, I would buy a DH take off cooler and pump that has all of the brackets. I spent extra money on a few items I didn’t need.
