Still overheating

From memory, I believe one of them is smaller than the other...that should be the water temp sensor. The larger one that looks similar is the thermotime switch.

This 280Z fuel injection manual should help, too:

Cool link Chloe. I hadn't seen this one before. Thanks!

I think I'm going to change the water temp. sensor and see what happens, I found one for 20.00 at autozone. Thanks for the help guys. I'll post again to let you guys know whats going on and Merry Christmas.

From my experience, I am leary of buying Z parts from Autozone, Kragen, Pep Boys, etc. Especially when it comes to FI oriented parts. These parts are used on many other vehicles. The Thermotime switch, temp sensor, thermal transmitter, air regulator, cold start valve, etc. used on a Z are very similar to the one used on BMW's and other euro cars that have Bosch FI. The problem is that although the pieces look the same, their specs might be different. I don't think that the chain type auto parts stores know the difference. Better off getting those parts from a supplier that specializes in Z cars.

Thanks for the info guys. My car, I just figured out, does'nt do this unless I take it on the highway, if I'm driving in the city, after I let it sit it will start right back up, its only when I take it on the highway:ermm:. Stephen I have a motorsport book for Z's should I just get the water temperature sensor out of there. Thanks.
