GTM Differential Cooler Kit install, Anyone done this?

Cooling the viscous LSD helps to keep the inner silicone oil from deteriorating early. After 60k miles on a viscous LSD, the LSD tend to function mostly as an open diff. The loss in function occurs gradually, cooling prolonging the process, just as a water jacket around the engine cools an inner jacket of oil.

I would def suggest dropping the diff, or at least taking off the rear cover. I DO NOT SUGGEST drill and tapping a hole with the cover in place. Even when placing the temp sensor low (which is what I did, to measure the reservoir) there are a few baffles inside that can block the probe from mounting properly. You should drill and tap once you are able to view BOTH sides of the cover.

On my picture, you will see I have the temp probe (brass, at the lower right corner of cover) and the drain plug is now an AN stainless fitting, as well as the fill hole. My setup uses the temperature probe to tell the pump when to turn on and off, only circulating the oil once it reaches a "high" temperature, and not while just at normal operating temp.
