what you need is a remote thermostat that by passes the extra cooler under 200F, 200F and above the thermostat activates and routes the oil through the cooler. They are available. Perma-cool.com don't know the price, but will save a lot of heartache down the road.

Has anyone had any problems with the fitting between the elbows and the Tru-Cool oil cooler?

My friend and I did the mod and everything was fine, but after the road test the was some bad leaking around the elbows. We pulled them off and found that the treads were stripped off the elbows. I think that we might have been shipped the wrong size elbows. While he was installing the elbows he complained the they were tight, but he thought it was to prevent leaks. Luckly the oil cooler threading doesn't look damaged.

Those are tapered NPT threads. Overtightening them could be a problem with the aluminum fitting. There are steel elbows available too that should be a little sturdier. I did use some sealing tape originally, but had to re-seal one so I used a high temp Loctite sealer on the other...Both work. Do not over tighten after snug and in alignment

Thanks for the info. I think he over torqued them. He was cranking on them pretty hard. I should be getting some moe fittings in today.

I would not hold my breath on that. Their position on this:

Aggressive driving of the 370Z on a race track at sustained high engine speeds can cause increases in oil temperature and may activate this engine protection system. To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty.
