In front of my radiator on my 2005 Roadster is something that looks like an oil cooler. I have a copy of the 2004 Service Manual which states that the 5-sp Auto has an trans cooler but I have a 6 sp manual, so is it an unused trans cooler or an oil cooler, any ideas.

PS if it is a trans cooler, does Nissan but then on all 350Z? What a waste of money. Could it somehow be used as an oil cooler?

 

its an oil cooler i have it on my touring

 

That was what I thought but the Service Manual shows the old being cooled by water from the radiator. The water comes from the thermostat inlet to a cooler at the base of the oil filter.

 

I just followed the lines and found that it was a power steering cooler!

 

BS REALLY the dealer told me it was a freaken oil cooler

 

Well it is an oil cooler, just not the oil you were thinking of.

 

I found the cooler in the Service Manual and is DIFFENTLY a power steering Cooler! It would have been better to have been an oil cooler.

The 350 does has a type of oil cooler but the oil is "cooled" by water from the regular radiator which is piped to a “cooler” at the base of the oil filter

 

oo
