Product Details
The Gates Coolant Outlet line is engineered as a cost-effective replacement for common thermostat housing and water outlet service needs. Gates focuses on improving the design, material, and manufacturing issues often found in aftermarket alternatives, and this part follows that approach with an aluminum housing and OE-style fitment. The CO35078 is a direct replacement for cooling system repairs where the original coolant outlet has cracked, leaked, or degraded over time. This part cross-references CH2111 and DS7Z 8501 C for the same application.
Common Repair Uses

Installation Notes and Tips
Verify the vehicle year, make, and model before installation. Inspect the mating surfaces, hoses, and adjacent cooling system components for wear or contamination before fitting the new outlet. Because this part includes a seal, confirm the seal seats evenly and the mounting bolts are tightened to the vehicle manufacturer’s specification. After installation, refill and bleed the cooling system according to service procedures to help prevent trapped air.
Quality Assurance
Gates designs its coolant outlet program to provide OE-style fit and performance with attention to service life. The aluminum construction and application-specific design support reliable cooling system repair on the listed Ford and Lincoln vehicles.
