Diff cooler and inline filter

Also, diff cooler setups like this are easy for install, but can be a PAIN to purge and fill up later. You have to purge the system and then make sure you have the proper level in the diff. The only way you can do that is to run the pump with the line disconnected from the return and allow it to pour into a bucket while filling it up at the same time.

If you drilled into the diff case and put a seperate return port, you could then use the factory fill port as it was intended with less mess. I recommend going this route.

A few comments since I have done a few of these:
- MAKE SURE you put an isolator between the pump and the chassis. The vibration from the pump will be annoying unless you are going hardcore race car.

- Buy a pair of high quality electrical connectors and make the pump removable. Otherwise you will be cutting the harness up later if you have to service the pump.

- While you are attempting to cool the diff. Go ahead and buy some DEI Titanium Exhaust wrap and wrap the exhaust portion near the diff itself. The radiant heat from the exhaust is a contributing factor here.
