Your cart is empty.A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.0L cooling system with a Nishimoto Ford 6.0L Power stroke Low-Temperature Thermostat and aluminum housing! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Nishimoto thermostat has a lower activation temperature (185°F) compared to the factory thermostat (192°F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing/driving conditions. The cast aluminum housing will provide a proper seal and will not rust over time. Like all of our Power stroke Performance parts..

Can't use the oring that comes with the kit. Too big. Will need a factory oring to install.

Once I got the broken bolt fixed lol...it fits perfectly the same as OEM .... only thing I can say is the "O" ring was slightly to large for the machined grove...but did seal so I guess.....

This is a quality part. It is well machined and a perfect fit on 05 F250 SD 6.0 diesel. I love the lower temperature (187F) opening for Kansas weather which can be extreme. I coupled this with a Fix UR 6 Backflush system for my oil cooler and the truck has never had more steady or lower deltas from the EOT (Engine Oil temp) to the coolant temp. Our weather is relatively mild now so will need to see performance in 100 degree Kansas heat but I think this will only help maintain a more efficient engine oil temperature

I bought this thinking it would be a upgrade to OEM. Put it in and didn't make it 1/2 mile from home and truck overheated. Let it cool off and tried to get back home. Overheated again. Next day came out to find a huge puddle under the truck. Now radiator is leaking. Not a oem either. A Mishimoto that was only a couple years old.Sure, all Mishi stuff have a warranty. Their staff was very prompt and helpful. But they surprise you with a $125 "warranty shipping" charge when you make a claim. I figure since their faulty thermostat caused the entire problem they should get the parts back to you for free but that's not how it works. Keep that in mind before you order.

Great fit, quality product. Would definitely recommend it to a friend! Fixed my over heating problem when towing heavy trailers.
