FAQ - Question 3
Do all water pumps look the same?
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.
Good Maintenance Practices - Section 3 - 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 2 - Bullet 2

Features & Benefits - Bullet 1

FAQ - Question 5
Does the water pump work when my vehicle is turned off?
FAQ - Answer 5
No. Your vehicle's water pump keeps coolant moving as long as the engine is running and stops when the engine is turned off. If you want to be able to circulate coolant for a short time after the engine has been turned off, an auxiliary electric water pump is needed.
Good Maintenance Practices - Section 2 - Header
Tips for Water Pump Inspection:
Good Maintenance Practices - Section 3 - Bullet 9
After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.
Good Maintenance Practices - Section 2 - Bullet 4
A stain around the weep hole is acceptable. However, if a weep occurs with the engine running and the coolant system pressurized, then the water pump should be replaced.

Signs of Wear & Troubleshooting - Section 2 - 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.
FAQ - Answer 4

A malfunctioning water pump can cause your engine to overheat, which may result in severe and costly engine damage.

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).
