🔧 Product Description

⚙️ Key Features
- Thermostat rated at 86 degrees
- 0.404 kg
- Supersedes part number 21412643
- Listed for five D series engine applications
- Within 14 grams of thermostat 22820756, so the rating and not the weight identifies it
🔌 Function
Blocks flow to the heat exchanger until the coolant reaches its rated temperature, then opens progressively so the engine warms quickly and then holds a steady running temperature.
⚠️ Common Signs of Failure
- Engine slow to warm up, or running below normal temperature on a cold day
- Overheating soon after start-up with the upper hose staying cold, showing a stuck-shut unit
- Temperature swinging up and down instead of settling
- Corroded or scaled valve and seat, so the unit no longer closes fully
- Wax capsule leaking or the return spring collapsed on strip-down
🛠️ Service Notes
- Fit a thermostat of the correct rating only, since a different opening temperature changes how the whole engine runs
- Renew the housing gasket or sealing ring and check the housing face for erosion at the same time
- Test the old unit in hot water before condemning it if the symptom is intermittent
