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).
