Has anyone fitted a diff cooler to there cossie? Driving back from a show on sunday in 40+ degrees my diff decides to vent out a fair bit of oil been told by quaife its due to the heat so need to look at diff cooling options

 

S13 and S14 200SX Nissan's over here (UK) had them as standard so you may be able to lift one off them.
They had a pump but you needed to trigger the diff oil temp AND speed switch to activate the pump. Temp was around 130 deg C and speed over about 75mph on the S14.
S13 was same temp but any speed over about 6mph to trigger pump

 

I have pictures of a 2wd set up on the rear diff with a mocal cooler with fans on plumbed in to a thermostat switch.

They're on my computer at home, I'll dig them out

Big over kill if you ask me but the cooler alone should be enough
