Product Description

This Cooltec Thermostat Housing 82°C is designed for the cooling systems of select Toyota models. It houses the thermostat element, which regulates coolant flow and helps maintain the engine's optimal operating temperature. The integrated 82°C thermostat ensures that coolant begins circulating at the correct temperature, protecting the engine from overheating or running too cool.

This thermostat housing is suitable for Toyota vehicles such as the Fortuner, Hilux VII and VIII, and Prado fitted with the 4.0L 1GR-FE engine. Always check your vehicle's model, year, engine size, and engine code to confirm compatibility before purchasing.

A faulty thermostat housing or thermostat can lead to symptoms like engine overheating, erratic temperature gauge readings, coolant leaks around the housing, and poor heater performance. You may also notice increased fuel consumption or the engine struggling to reach normal temperature.

Replace the thermostat housing if you notice leaks, cracks, or if the thermostat is stuck open or closed. Regular checks during cooling system maintenance help prevent unexpected breakdowns and costly engine damage.

Trust MiMi Auto Parts for quality cooling system components and reliable nationwide delivery across South Africa. Our team is ready to help you find the right part for your Toyota, ensuring peace of mind on every journey.
