Need4Speed Posted October 20, 2010 Share Posted October 20, 2010 Am I right in thinking that the diff cooler pump is electric and only pumps when the oil needs cooling? Just fitted a new cooler today and it's stone cold. Link to comment Share on other sites More sharing options...
bignum Posted October 21, 2010 Share Posted October 21, 2010 Yes there is a temp sensor on the diff somewhere so the pump only works when the oil gets hot enough, there is a way of triggering the pump manualy but can`t remember how. Link to comment Share on other sites More sharing options...
