From the service manual:
It's item number 10. You can also see it in this pic (where the brass fitting is):

The oil temp sensor is located by the oil pump. Thanks Semtex. The oil temp should be near uniform in the base pan. Therefore, the oil is entering the pump at say 260F for arguments sake. Before the oil reaches critical components such as journal bearings, does the oil gain heat, lose heat or remain constant while flowing through the oil galleries prior to entering the journals?

Very well said FricFrac and I couldn't agree with you more. BTW for a 19 row Nissan Motorsports cooler + installation at the dealer (Nissan can’t complain about warranty issues if it is a Nissan part installed by a Nissan trained mechanic) will run you around $1000 bucks. I will find out the total cost in 2 weeks after i get mine installed. |

it would be nice if nissan recommends the oil cooler for hard or hot driving as their previous email suggested, and that if you use the nissan (nismo) part and it is installed by the dealer, that it would be covered by the full warranty. as it stands, with it being specifically disclaimed, they are making a very bad decision in my opinion. i would not paying for it as a dealer installed option, but it should be part of the warranty. terrible.

has anyone else noticed that the oil temps stay significantly lower when you have the AC on? I was driving the other day through the city with the AC off and temps rose to 225 and stayed there. Parked, got out, ran some errands, got back in, twas hotter now of course, turned the AC on, drove around for about 45 minutes and temps stayed at 200 the rest of the time. Anyone know why this is?

Found it. http://www.the370z.com/nissan-370z-g...html#post57403
Speculation is that turning on the AC turns on an additional radiator fan. Keep in mind that the oil is water-cooled, so it kinda makes sense.

The electric fan is almost always controlled by the AC switch. Same switch as the compressor. Used to have to keep mine on even when my compressor clutch was out on my old Dodge Spirit (I had the Spirit!). If it was off I stood a much larger chance of overheating.

That said, then the oil will cool prior to flowing to the critical components as the water temp is about 190-ish. Maybe the oil temp issue wasn't?

pretty cool really, but the parasitic power loss is IMMENSELY noticeable with the AC on.

Yeah it is. That's probably the biggest thing I noticed after installing a UD pulley. It drastically reduced the impact of turning the AC on.

You can always cut the power to the A/C compressor or wire a second switch to the 2nd fan if you're fanatical about lower temperatures, but 225 is pretty normal.
