⚙️ Key Features

• 24 applications on D series engines
• Supersedes 3826604
• 2.3 g

🔌 Function

Routes coolant past the main circuit until the engine is warm, then closes off that path so full flow goes through the cooler.

⚠️ Common Signs of Failure

• Engine slow to reach normal running temperature
• Temperature running high or swinging under load
• Uneven warming of the circuit hoses
• Valve found stuck, distorted or clogged with scale on strip-down

🛠️ Service Notes

• The number this part supersedes, 3826604, also appears behind thermostat housing 3809577 and cap 3809621, so that older number covered an assembly now supplied as separate pieces — check which of the three you actually need
• Renew the gaskets and O-rings in the housing while it is open, and refill and bleed the circuit fully
