 VW Jetta

I’ve got a water pump that needs replaced…can it be done by myself or is it best to take it to a mechanic?



According to the Labor Time Guide this is a 6 hour long procedure for an experienced mechanic. Noting that and the fact that you asked in the first place, Yes, take it to a mechanic. This is probably not the project you want to start learning on. Also the water pump is driven by the timing belt.
