A Must-Have for Your Car's Cooling System

This thermostat kit is a game-changer in the Automotive world! It keeps my engine cool and running smoothly on even the hottest of days. The installation was a breeze and didn't require any special tools or knowledge. The only downside is the price is a bit steep compared to other options on the market. However, the quality is unmatched, and it's worth the investment for a reliable cooling system.

Pros
  • Easy to install and replace existing thermostat.
Cons
  • May result in higher costs compared to other thermostat kits in the market.

worked 10 minutes.

Installed to prepare for winter. Of course everything will be fine next season. The original was 22 years old. Good price and timely delivery. Never had problems with Sierra products. Will upgrade to 5 starts in 20 years if still going strong!

Pros
  • Designed for use in Volvo Penta applications
Cons
  • Nothing
