I have a 1993 240sx with a SR20det swap. Whenever I ran with the A/C on the car would overheat. I replaced the thermostat and my overheating issue stopped. Great for anybody running A/C with their swap! It helps maintain the perfect temperature.

Fits just fine in both my KA24E. It should fit the KA24DE as well. Start up procedure takes longer, (expected), works perfectly. No issues so far and it's been a year.

At a cheaper price than SARD and all them other brands, why not go for top of the line for nissans right? This thermostat even opens at a colder temperature than the more expensive one. 62 degrees C compared to 68, or 74 (stock) sounds damn good to me. All the longer my motor will live now that my heat soaked sr20 can get some coolant that much sooner. I wish they would have put a little tiny bottle of RTV high temp gasket maker in there for us SR20 users, because we cant just go to autozone and buy a gasket, but hey, ill live. My first nismo part...interesting. Thank you FRSport.
