Why Upgrade from the Stock Thermostat?
The OEM thermostat typically opens at a higher temperature, which can delay coolant flow under extreme conditions. Opening earlier gives your cooling system a head start, helping reduce heat soak and thermal stress on engine components.
Installation Notes
- Difficulty: Medium
- Requires standard hand tools, coolant drain, and proper system bleeding.
- Great time to inspect/replace coolant and related hoses for maximum reliability.
Note: Always verify exact fitment with your vehicle’s VIN and model year before installation.
