High quality replacement part at an excellent price!!
I installed this in my 2018 Nissan Frontier Pro 4X truck. Exact fit, high quality part, works very well. Does not come with a gasket. I recommend a high quality fel pro gasket and some high temperature silicone sealant. This part solved my problem, arrived quickly, and was remarkably less expensive than local prices for the same exact part.

No gasket
Can't go wrong with Aisin products. Fixed my wandering temp gauge, rock solid now. This does not come with a gasket.

‘10 Frontier operates just as it did new. This is the OEM part, thus highly recommended. It’s been functioning normally for 1.5 yrs now.

ASIN THN-007 Thermostat - Works like a champ on 2004 Infiniti G35X sedan
This replacement part works well in my 2004 Infiniti G35X sedan. My mechanic installed this part and also replaced the twin radiator fans. Now my car is driving well like before. This part is meant for the sedan. If you have an Infiniti G35 Coupe then you will need a part rated for 170 degrees instead of 180 degrees. Make sure you also buy a Thermostat gasket. I had to purchase that separately. I prefer to buy Japanese manufactured / designed parts for Japanese cars.

This one works
I bought a motorad one for cheaper locally, because it was in stock, same price as the one on amazon. And it didn't do anything good. I kept bleeding, it kept overheating. Hot bottom, cold top hose. Installed this one and it worked! It started a bit hot after initial fill, but as I bled it, it went normal. Expensive, plus separate gasket, but worth it. Don't bother with the thermostats that don't have the extra metal shield over the spring on the side. They don't work. Don't waste your time, you'll have to do the work twice. This one is the most expensive one, but there are a couple others that may still fit the application fine.
