Junk

Constantly gets stuck. I Noticed when my car started overheating so the first thing I checked was the Thermostat and just as I expected it did not open. It Wasn't worth returning.

This thermostat and house, are connected together.

Can’t use thermostat alone. It’s attached to housing.

It’s as good as it

It’s as good as it gets. It added about 40% more flow trough the radiator. As apposed to them cheaply Chinese made stats you buy at the local parts stores.

54mm diameter, not 52mm as advertised.

As a product it appears to function fine, but it is 54mm in diameter, not 52mm as advertised - so it will not fit 90s Fords like the oreilly website says it will.

Radiator thermostat aids car coolant system

Solved overheating on my 2001 minivan. Replacing this very important part of cooling system is important. Radiator caps are part of thermostat control just like new hoses.

Great Thermostat.

Actually keeps the right temperature in my old dodge pickup. Its a three speed but still helps at keeping the temperature low at higher speeds.
