Terrible thermostat kit; avoid buying!

My analysis of this automotive part showed that it was poorly made and did not function as expected. The instructions were also difficult to understand, making installation a nightmare.

Pros
  • None
Cons
  • Poor quality, confusing instructions.

Thermostat fits and works as intended

Worked like a champ in a Mercruiser engine. I ended up using an OEM gasket as the Sierra gasket didn't have metal inserts for continuity.

Pros
  • Includes the following: 18-2553 Thermostat cover gasket, 18-2917 Thermostat gasket, 18-3649 Thermostat
Cons
  • Expensive

This is a thermostat kit.

Not much to see here just the thermostat and gaskets. I have found that the thermostat housing gasket in this kit is not suitable for my application even though it says so. I needed a gasket with rivets. The rest seems ok.

Pros
  • Sierra Part Number: 18-3644
Cons
  • Exterior
