Hi to all. Alittle techical question. I am in the middle of replacing my rear sub frame in my 90 spec uk tt. My question being, can you get rid of the diff cooler , that inturn feeds a small radiator to the side of the rear sub frame and from that , cooling pipes that lead out to the rear of the car behind the rear bumper...I'm not exactly michael schumacher on the roads and would generally not drive the car as such, but for the odd blast here and there...Am I right in believing that the jap spec versions of my car do not carry the cooler at all? Then why do the uk one's have one ? :cool:

Because they know that us and the Aussies are hooligans that not only rag our motors to death, but also not the hotest on oil changes. Hence an oil cooler and a sealed unit.

Hi Mark, thanks for the answer, but as before, can I just dis-connect the cooling part of the diff?

Forgot to add...and only drive like Michael Schumacher the very very odd time!!!

You'll need to get someone with a greater knowledge than me on this one. Though I personally would say yes, because like you say the Jspec doesn't have this and yet I believe the diff ratios are the same. + The vast majority of Zed's in the UK are imports and don't seem to suffer with diff proplems even when running quite high (400 ish RWBHP)

 

So I'd say go for it. I bet someone will come on here and tell me how wrong I am now. :rofl:

Thanks Mark....hopefully someone will come around tonight and be able to help...Any helpers out there?

hopefully , there are some of you good folk, who are techncially up for this question...not your usual easy pessy stuff, like moddin lol

It only comes on above about 90mph and when its hot weather. I didnt know it was even there at first till I saw oil leaking onto one of the exhausts after a fast run due to a slack connection. Its a clever system that cant drain all the oil in the event of a leak either so its fail safe.

 

There is a thermo switch to turn it on and you can test it easily by shorting the terminal. If you've got it why junk it. I heard of one zed owner who ruined his rear diff (non Euro spec) after a thrash at 155mph. In reality few people ever can test those limits for any length of time and stay out of jail and its only at continuous operation at those speeds where the diff would be at risk.

 

Course loads would say they do humungous speeds and no probs without it but how oftern have you heard of escorts that did 140. It really has to be 155mph limiter type speeds for a decent time in warm weather before the oil would overheat and risk the diff.

 

Fact is if you dont do very high illegal speeds then you wont ever miss it. If it aint broke then dont fix it either. Nissan didnt fit it for decoration.
