Product Description
Z1 Low Temperature Thermostat for all Nissan & Infiniti models equipped with the VQ37VHR / HR (Hybrid) powertrains.
The Z1 Low Temperature Thermostat opens up at 76.5º C (169.7º F)*, while the OEM thermostat opens at 82º C (179.6º F). Opening at a lower temperature allows the coolant system to keep the engine temperatures lower.
Some other aftermarket low temperature thermostats may open at lower temperatures, which is great for track cars, but for street cars that are not constantly put under heavy load will never reach proper operating temperatures. The Z1 Low Temp. Thermostat ensures that your street car still reaches proper operating temperatures but still keeps temperatures lower than stock.
* This thermostat may cause your vehicle to throw a CEL for code P0128, which is due to your engine coolant temperature being below the OE thermostat regulating temperature.
NOTE: This thermostat does not include a thermostat gasket, it will need to be purchased separately.

My 2012 370z Sport Touring 6MT with 72k miles has always had cooling issues since I bought it. Coolant temp would go over even while sitting idle with the A/C on and start blowing warm air. Oil temps would go over 230F (sometimes 250F) after a few good pulls even with a 19row and then a 34row oil cooler. I recently installed this thermostat and all my issues have been resolved. My oil and coolant temps don’t go over 210F even after some spirited driving. The car is now supercharged and made 622whp on E85 but I drive around on my 533whp MAP and still no issues on either MAP.

Great quality, fast shipping and good packaging. Fairly easy to install. Works exactly as advertised. Great to enjoy spirited drives without having to worry about heating up too quickly with this upgrade.

Working great. Keeps the temperature so far no higher than 183F. I will continue monitoring to see if it’ll be enough. I live in a hot climate and I want to keep the temperature under 190F . If not enough then I’ll have to add an oil cooler.

So far so good I live in Vegas and it’s about to get real Hot! So far what I have noticed is the Low temp Thermostat has decreased the temperature by 1 dot on the 370Z dash…I’m happy!
