I posted in the Help forum about my heat issues and it was suggested that I shouldnt be running a 190 thermostat...(Thanks Carl) I have checked with Courtsey, BD, and MS and cant find anything in the 160 range.

Where can I get a 160 or 170 thermostat??

Thanks,

I'll try them again, our local Nissan parts guy said he could not get them.

Thanks,

Try http://www.nissanparts.cc/ type the number in the search box.

Thanks for the link, I was not aware of them.

Don't forget that the chevy 350 thermo is the same size as the Z thermo. If you are still running to hot after the 160 thermo, you might look at the radiator being clogged and not providing the right water circulation.

I prefer the design of the oem thermostat.

I gut the thermostat and use only the restrictor plate with a thermostatic radiator fan on my 240Z. Although the NAPA units work well on both my daughter's and wife's 240Zs.
