Product Description
GM Genuine Parts Heater Water Pumps are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These water pumps are used in some vehicles to pump engine coolant during certain operating conditions. While your engine's main water pump is mechanically driven and stops when the engine does, a heater water pump is electric and able to circulate coolant to the heater core during engine shut off, keeping coolant flowing and the heat going. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). ⚠ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
Features & Benefits - Bullet 5
GM regularly updates production and service part designs to integrate new materials and technologies
Good Maintenance Practices - Section 1 - Bullet 3
Inspect for leakage at the water pump outlet housing or the rear cover gasket, and leakage at the water pump vent or weep hole.
Good Maintenance Practices - Section 2 - Bullet 10
Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
Signs of Wear & Troubleshooting - Section 1 - Bullet 1
Leaking Coolant - Puddles of coolant under your vehicle, a constant drip or stream of coolant from the water pump's weep hole, or a constantly empty or low coolant reservoir are all signs of potential water pump wear, and may be caused by cracks in the pump, or seal or gasket failures.
Good Maintenance Practices - Section 2 - Bullet 5
Never strike the water pump shaft, since this will damage the new water pump.

Great Product, Cost, Shipping, Installation
I'm not a mechanic though I'm handy and have plenty of tools. After watching Atlantic British videos on YouTube I decided this is something I can do to stay in budget. After power washing oil off the area I spent the first day removing the fan clutch assembly which required a large narrow wrench (I chose to use a large crescent wrench) and removed the old water pump. Next I cleaned the area again with the power washer. Next day I installed the new pump with gasket noting which bolts came out of which position, then removed the protective plastic thread collar on water pump and reinstalled the old fan clutch assembly. The only frustration came trying to keep the gasket in place while positioning the new pump. Some gaskets come with a tacky side to stick to the pump or engine side and that makes it easier to keep it lined up. Future suggestion perhaps.

Water Pump
I received water pump in a too large box, not packed to keep boxes from moving around. I have not installed water pump due to weather changed & too cold & wet.

Loved My Service.
The part was in a padded box tightly secured and everything was perfect. It was a new part with all the seals included. It was very easy to install and is working like a champ. Now all my male friends come to me to get their parts online for the great prices and great quality parts.

Purchased For My Boyfriend
This was a replacement part as the original started to leak after 100k miles. It was fairly east to install ourselves and had no surprises that came along with it (wrong part or just didn't fit right).
