Surprisingly Reliable!

Had some hesitation with purchasing since it wasn't a top brand but decided to give it a try. Based on our own experience, it works well and lasts for more than expected lifespan. It made a noticeable difference in the engine cooling performance!

Pros
  • Affordable, reliable, made a noticeable difference in engine cooling performance.
Cons
  • Not a well-known brand, may not fit all types of automotive engines.

As detailed in the Parts section

No problems with the kit, easy to install. Fast delivery. No damaged seals or O-rings. I use this on Mercuriser 3.0L 181.

Pros
  • Temperature range: 160Β°F
Cons
  • Not as thick as other picks

The only washer that worked for my application was the .

The only gasket that worked for my application was a riveted gasket, very specialized. Once the gasket material got wet, it basically dissolved and flew out from under the thermostat housing under pressure. A serious mistake, as a result of which the hold quickly filled with water without my knowledge. Try to find an OEM Mercruiser kit

Pros
  • Fits 1987 to present GM engines with standard cooling requiring a 160 degree thermostat.
Cons
  • So far so good
