Stop the drippy drips - Replacing water pump, timing belt, tensioner, pulleys on 2000 Subaru Impreza

About 2 weeks after getting the Impreza back from the dealer for replacing the head gaskets, we found coolant under the car. It’s leaking from the weep hole of the coolant pump and the pump needs to go. Not taking it back to the dealer - going to do it ourselves. It involves removing the timing belt. Since it’s been a long time since the idler pulleys and belt tensioner were replaced, we went ahead and replaced those as well. Learned a lot along the way so we’ll show you how we did it and what we learned. With new head gaskets, timing belt, water pump, tensioner, and pulleys, we shouldn’t be back inside the timing cover anytime soon! (knock on wood)
Note that I made a post on the Community tab of my channel that has the “memory jogger” procedure I made and followed for doing this work, along with some additional notes about torque, etc. Be sure to check it out on the channel’s Community tab/area.

Thanks for the feedback, Eirk, and thanks for watching. I'm glad the video was/is useful. I agree, finding content for this one seems to be a challenge. Thankfully (?) this car has over 250,000 miles on it so I'm betting there's a lot more 2.5rs content in our future...
