The list above is for reference. It is crucial to verify the engine type, temperature (82°C), and flange dimensions (70mm / 51mm).
When replacing the thermostat, we always recommend replacing the thermostat housing gasket (if not integrated) and inspecting the coolant hoses and their clamps.
A failed thermostat is dangerous. If it sticks closed, it will lead to rapid overheating and engine destruction (cracked head, blown gasket). If it sticks open, the engine will fail to reach its operating temperature (82°C), drastically increasing fuel consumption and accelerating cylinder wear.
The 02/203185 thermostat is an automatic valve in the cooling system. When the engine is cold, it stays closed, blocking flow to the radiator (the "small circuit"), allowing the engine to warm up quickly. After reaching operating temperature (here 82°C), it opens, sending coolant to the radiator (the "large circuit") to maintain optimal temperature. This product is a complete kit including the thermostat and its housing.

This is the temperature at which the thermostat *begins* to open. It is a critical parameter for modern engines (like Tier 2) to ensure optimal operating temperature for full efficiency and low emissions.
Yes, this is the most likely cause. It means the thermostat is stuck in the open position, and coolant is circulating through the radiator constantly, preventing the engine from reaching 82°C.
This thermostat is very universal. It fits many engines from the Perkins 1100 family (1103A/B/C/D, 1104A/C/D) with codes like RE, RG, RJ, NK, NL, DC, DD, etc. It also fits many older 1000, 400, and 100 series engines, as shown in the application list.
