Thermostat for the 2.5L 200TDi diesel engine, operating within the thermostat housing at the top of the cooling circuit.

This thermostat opens at 88°C, allowing coolant to flow from the engine to the radiator once the set temperature is reached. Below this threshold, the thermostat remains closed and directs coolant through the engine bypass circuit to accelerate warm-up and maintain stable operating temperature.

Frequently asked questions

What does the ERR2803 thermostat do?
The ERR2803 thermostat controls coolant flow on the 2.5L 200TDi diesel engine. It opens at 88°C, letting coolant flow to the radiator once the engine reaches temperature. Below that it stays closed, routing coolant through the bypass to speed warm-up. It sits in the thermostat housing.
What temperature does this thermostat open at?
This thermostat opens at 88°C, the correct rating for the 200TDi engine. Fitting a different temperature changes when the radiator circuit opens, which affects running temperature and cabin heat. The 88°C rating is matched to the 200TDi cooling system.
What are the signs the thermostat needs replacing?
Overheating, a gauge that won't reach normal temperature, slow warm-up or weak cabin heat typically point to a failed thermostat on the 200TDi. Stuck open it runs cold; stuck closed it overheats. Replacing it restores stable running temperature.
Which Land Rover models use this 200TDi thermostat?
This thermostat fits the 2.5L 200TDi in the Land Rover Defender up to 2016, Discovery 1 and Range Rover Classic. Discovery 1 fitment runs to VIN LA081991 and Range Rover Classic from VIN JA610294. Confirm your engine is the 200TDi.
