How does the housing affect cooling performance and durability?

This component ensures coolant flows through the thermostat area and out to the radiator and heater core as designed, helping maintain stable engine operating temperature. Manufactured to pass hardness and crush tests, it resists warping and leaks that can compromise cooling and lead to overheating.

• Neck angles and outlet sizes engineered for proper coolant flow (15° neck angle)
• Outlet diameters: 0.875 in and 1.44 in to match original hose connections
• Tested for structural integrity to minimize leaks and seal failure

How do I confirm fitment before purchase?

Verify the part by matching your vehicle year, model and engine to the listed fitment and cross-reference the provided reference numbers. Check the outlet diameters, mounting hole spacing and connector type against the original part to ensure correct fit and avoid returns.

• Compare reference numbers: 902-846, 1511105, CO34825, etc.
• Confirm sensor connector: 2-pin temperature sensor match
• Measure mounting hole diameter and outlet sizes against your old housing
