Only fail-safe is designed to lock in the open position when overheating occurs due to a failing cooling system component. This allows maximum coolant flow, thus preventing expensive engine damage.

Well i wont give it less stars yet because it still works. But we will see after 4 to 5 years till the next long life coolant change.

Install was easy on my 2009 Town and Country van. The thermostat appears to be made good and it works great. I would recommend installing it.

This thermostat fits and works great as a replacement for oem on the 3.8L engine on Jeep JKs (2 or 4 dr) , 2007-2011. The new one is on the right in the photo. I recommend replacing the thermostat housing as well. (The Dorman brand is available at Amazon $35). Remember to burp out the air in the coolant system ! i had to use the messy method of idling the engine for 15-20 minutes (rad cap off) because the funnel kit did not work on my rad neck.

Fits great took literally 5/mins too install. Also I don't know squat about cars. So my big thing was to have a product I could install myself easily, and would be good quality. This fit the bill. Will definitely order from them again.

I heated it in a pot next to the old one i have, didn’t open all the way unlike the old one.

Like my ex, this thermostat is a bit too sensitive. My engine runs just a bit cooler than it should. Unlike my ex, the sensitivity isn't a deal breaker because it isn't an unbearable burden in my life.

Purchased a thermostat and it had a tab on the rubber gasket. It was stated to fit my model and year van. It didn't. This one fit like a glove with no leaks. It makes the car warm up in record time for very cold days and keeps the car cool when in hot conditions.
