This was one of the items I needed for my car overheating, it was cheaper here from Amazon than the dealership they wanted ibelive $380

I have not yet installed this product but it came fast and looks like a quality replacement.MECHANIC NOTE*This does not come with a thermostat housing gasket and you will need to replace the gasket with this housing I would not recommend at all reusing any old gasket or installing without the proper one. Also drain coolant from radiator or drain plug and refill with recommended coolant DO NOT BUY COOLANT AT THE GAS STATION! I purchased this for a 2001 Infiniti I30 and the coolant is GREEN and will say ASIAN.

Perfect fit for my Infiniti FX 37.

Box was not sealed, half opened and the thermostat was just thrown inside, unwrapped. I wasn’t 100% sure if it was even new so I just returned it. I give it 2 stars because the part DID match the OE thermostat removed from 2000 Maxima SE. In the picture it looks greenish but surprisingly it was gray. Hope this helps.

Installed on a 1999 Maxima, worked great and fit well.

This was a perfect fit for my G37. You will need a gasket though. Because it's recently installed, I can't speak to how well it works and it's lifespan. If it goes bad early, I'll report back...otherwise you can assume all is well from the date of this review.
