    Fits like a glove Comes with gasket It’s actually OEM part Beats dealer price My infinit g35 was running cold, the temp levels would drop while driving on freeway and noticed it took a while to warm up to operational temps replaced this part was a little tripped out because of the price but it came stamped “Nissan” the car runs good now If you actually spent the time reading my review follow me on Instagram @_deadscience

  • Good product

    I had to replace the radiator on my 06 Nissan and figured might as well replace the thermostat at the same time. It has been a week now and everything is fine.
