VOE20506125 — Thermostat Voe20506125 For Volvo Engine Tad520Ge Tad530Ge Tad531Ge Tad720Ve Tad732Ge Loader L40 L40B L45 L45B

This thermostat regulates the engine coolant temperature by controlling the flow of coolant to the radiator, ensuring the D5D engine operates within its optimal temperature range. Manufactured to precise specifications, it provides reliable opening and closing actions, unlike a stuck or sluggish thermostat that hinders proper heat exchange. Operators may notice the engine taking excessively long to warm up, or conversely, running too hot if this thermostat fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A common symptom of a faulty thermostat is the engine taking an unusually long time to reach its normal operating temperature, leading to poor fuel efficiency and increased wear. If the thermostat becomes stuck closed, the engine will quickly overheat, potentially causing severe internal damage. If stuck open, the engine may run too cool, impacting performance and emissions.

Installation Tip

Always install the thermostat with the jiggle pin (if present) facing upwards to allow air to escape the cooling system. Ensure the sealing surface on the engine is clean and smooth to prevent coolant leaks.

Service Note

Inspect the radiator hoses and coolant level when replacing the thermostat, and consider replacing them if they show signs of wear or degradation.
