I changed coolant & thermostat recently. Purchased a thermostat from CarQuest & another one from NAPA.
When I showed the CarQuest one to the NAPA guy, he said - "I'd use the CarQuest one if I were you."
The CarQuest is a Stant (made in Japan) $18.99
The NAPA is a Standard-Thomson (made in USA) $11.99
When asking for the gasket for these thermostats,
each one gave me a paper gasket that fits between engine block & housing, neither of which fit correctly.
When I was more detailed in my request, (asked for o-ring that fits on flange of thermostat), they looked in a book & found it.
When replacing thermostat, the old one was a Stant & did NOT have a rubber o-ring on the flange.
As a matter of fact, I chose not to use the o-ring,
as it did not allow for the thermostat flange to lay flush into the depression on the engine block.
Anyway, no leaks or drips - works great...
Here's a link to comparison pic of thermostats.
Obviously, the one on left is the Stant, one on right is the Standard-Thomson...
