| Product Description | ACDelco GM Original Equipment Engine Water Pump Gaskets are used between the water pump housing and the engine block or another component to seal the interface between the components. The gasket may be made of fiber or a rubberized composite material that provides a liquid-tight connection. The gasket keeps the engine coolant in and keeps air out. These original equipment gaskets have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. ⚠ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov |

| FAQ - Answer 2 | Yes. ACDelco GM Original Equipment parts are equivalent to your GM vehicle's original factory components. |
|---|
| FAQ - Question 4 | Can a malfunctioning water pump harm my engine? |
|---|

|---|
| FAQ - Answer 5 | Yes. As part of regular cooling system operation, the water pump sends hot coolant to the heater core of your engine, which transfers heat into the passenger cabin of your vehicle. If this hot coolant is unable to reach the heater core, then this heat transfer cannot occur, and your passenger compartment remains colder than you want. |

|---|
| Good Maintenance Practices - Section 3 - Bullet 7 | Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems. |
|---|
| FAQ - Answer 1 | Yes. Always consult the Vehicle Owner’s manual or an expert technician before making any repairs or adjustments |
