⚠️ Common Signs of Failure

• Coolant weeping or dripping from the housing joint
• Engine slow to warm through, or running hotter than normal
• Corrosion or pitting around the sealing face
• Cracked casting, most often at a stud boss
• Sealing face distorted, so a new gasket still will not seal

🛠️ Service Notes

• Renew the gasket or seal, and consider renewing the thermostat while the housing is off
• The two housings supersede different earlier references across the same engines, so check which one the parts listing calls for
