- Cause: A cracked thermostat housing will result in a coolant leak, potentially leading to engine overheating and damage.
- Visual Inspection: Carefully inspect the thermostat housing for cracks or damage.
- Pressure Test: Perform a coolant system pressure test to ensure the system maintains pressure and observe for leaks at all split lines, including the thermostat housing and coolant crossover manifold.
- Solution: The Fleece Performance thermostat housing upgrade is a drop-in, direct factory replacement for the weak plastic housing that can become brittle overtime!
