Frequently asked questions

What does the ETC4761 74C thermostat do?

The ETC4761 is a 74C thermostat that regulates coolant flow through the engine on Land Rover 4-cylinder models. It stays closed until the engine reaches 74C, then opens to let coolant flow to the radiator.

Which engines use a 74C thermostat?

This 74C thermostat fits the 2.25 and 2.5 litre 4-cylinder engines used in the Series 2 and 3, and the Land Rover Defender. It is not used on the V8-engined Range Rover Classic.

What happens if the thermostat sticks closed or open?

A thermostat stuck closed typically causes rapid overheating since coolant can't reach the radiator. One stuck open causes the engine to run cold and warm up slowly, reducing heater output and fuel efficiency.

How often should the thermostat be replaced?

There's no fixed replacement interval for this thermostat, but it's worth replacing whenever you're chasing overheating or slow warm-up symptoms. Many owners replace it as routine maintenance during a cooling system service.
