Thermostat AISIN or Motorcraft

Soon as i bought Motorcraft all was normal again

I still changed my thermostat to an Aisin unit for peace of mind, so far so good.

I just bought two thermostat related parts off rockauto that are both Aisin yesterday.

I have installed them in two rebuilt, and they are working perfectly fine

Make sure you use the motorcraft thermostat.

Go with the Motorcraft thermostat as it has a rubber seal on the outside edge.

It's a very easy thermostat to replace, I just did it a couple days ago on a 2008 Hyundai Sante Fe with the big 3.3l V6. The gasket comes with the OE Aisin thermostat, too, making it even easier.

The OEM Aisin thermostat opens at 185, staying completely closed until 180 where it can open up partially allowing proper circulation and proper temperature control. The engineers at Nissan designed this cooling system to function in a certain way at very specific temps. ONLY USE THE AISIN 185 OEM thermostat in these trucks.

I replaced the thermostat from a non-OEM to Motorcraft about a month ago, and the only difference has been the speed at which the dial moves from higher temps to its normal positon.

I’ve had a Motorcraft thermostat fail after 100mi on my Ford
