Hello everyone,
Have a 2019 Ram 1500 Laramie w 56k miles. Have complained to the dealer from almost day one about a strong antifreeze smell in my garage that continued to get stronger and stronger. The were never able to find anything. Surprise, the water pump started leaking just after the warrantee was up. I replaced the water pump and made a video of it. Thought some of you might find it helpful if you end up doing it yourself. Here’s a link.

GREAT amateur video, complete with mis steps! Outstanding lighting and video quality. Much more work than I would tackle, but did appreciate your effort here.

Great video, a few choice cuss words would have made those hoses come off a little easier.
 
Yes, cuss words do help when removing hoses. So do these...


Can't tell you how many cuss words have been saved in my garage with these tools. Not to mention hoses, fittings, and knuckles.

Also, I'd recommend against using adjustable end wrenches unless you have no other option.
