Overview

The ECS Tuning Thermostat Replacement Kit is a comprehensive cooling system solution. By replacing these items at once, you can ensure your cooling system runs efficiently.

Show original supplier description

The ECS Tuning Thermostat Replacement Kit provides a complete solution for addressing common cooling system failures. Components within the cooling system are susceptible to damage from extreme heat and repeated thermal cycles, which can lead to warping, cracking, coolant loss, and severe engine overheating. This kit allows for the simultaneous replacement of these critical parts to maintain optimal cooling system performance and prevent potential engine damage. The kit includes a new temperature sensor, thermostat with housing and gasket, a water pump, two 1.5L bottles of G12 coolant, and all necessary securing hardware, gaskets, and O-rings. This product is backed by ECS Tuning's Lifetime Replacement Program, offering coverage for as long as you own the product. Please note that some kit components are covered by this program, while others, such as the G12 coolant, are not. Specific fitment details are available via the vehicle selector on the ECS Tuning website, which indicates if the product 'Does Fit' or 'Does NOT Fit' your selected vehicle. Oversized products and direct ship products may be excluded from free shipping offers.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
