| These are factory Nissan thermostats, the best on the market. We don't install anything else in the shop. They fit all A series, L series, and Naps-Z engines, and they come with an upper housing gasket for all applications. The recommended temperature setting for your z is 180 degrees. We can also get 160,170, and 190 degree t-stats if you need one, just let us know. We also sell aftermarket t-stats for a lower price. Call for details. These t-stats come with 3 or 4 different upper housing gaskets so they fit multiple styles of engines.
If you would like a lower housing gasket for the L engine cars, those must be purchased separately. See listing. We recommend lightly surfacing all t-stat housings before installing them, and using anti-sieze on all bolts. Last update 04/11 |
