Good To Know

Q: What happens if the thermostat gets stuck closed? A: A stuck-closed thermostat blocks coolant flow, causing rapid overheating that can damage the engine. Replacing with this 82°C thermostat prevents that risk.

Q: Does this thermostat come with a gasket? A: No, the gasket is not included. You should reuse a good-condition gasket or purchase a new one separately to ensure a proper seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
