Product Details

The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After reaching operating temperature, it opens up to allow the coolant to flow through. If the thermostat gets stuck closed, it allows no fluid to flow and ends up overheating the coolant already in the engine. When it's time to do a thermostat replacement on your vehicle, it makes it much easier if you have everything that you need before you get started.

This kit includes the ECS Billet Aluminum J-Plug to replace the plastic component that can become brittle over time from exposure to constant temperature changes.  ECS' Billet Aluminum J-Plug is machined 6061 aluminum for a strong yet lightweight plug that will not fatigue, and anodized in black for protection against any future corrosion. The strongest, longest-lasting, best looking solution on the market.

This kit, assembled by ECS, includes everything you need to complete your thermostat service.

Kit includes the following:

  • ECS Billet Aluminum J-Plug
  • Thermostat Assembly - Includes housing, gaskets and sensor
  • Water Tube O-Ring
  • Necessary Hardware

During your thermostat change, fluid loss is inevitable. Be sure to browse the website to get the proper replacement for your vehicle sent directly to your door.
