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. Quote 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. Quote Link to comment Share on other sites More sharing options...
