About this part

Product Details

When you're working on your 2003-2024 Toyota 4Runner 4.0L, a reliable cooling system is key. This Mishimoto Low-Temperature Racing Thermostat comes as a complete unit with its housing, making it a straightforward replacement for your stock thermostat. It's designed to help prevent overheating, especially if your 4Runner sees a lot of action.

What sets this thermostat apart is its lower activation temperature. While your factory thermostat opens around 180°F (82°C), this Mishimoto unit starts opening at 160°F (71°C). This means coolant circulates through the engine sooner, helping to maintain lower overall engine temperatures. This can be a real benefit if you live in a hot climate, have added power to your engine, or frequently tow heavy loads or drive under demanding conditions.

The housing is designed to fit just like the original, ensuring a good seal and an easy installation process. It's a well-built part that's ready to go right out of the box.
