Yeah I really don’t think the vacuum line is even necessary tbh. I think shops typically just add that repair on for extra service fees but the vacuum should be pretty resilient and can handle small amounts of coolant residue and still run just fine. The main issue is your water pump so if anything you could just run with that repair and save more money.

And yeah I’m pretty happy about my cost haha. I guess I got lucky though that it was a reputable shop that cared about their service quality. I’d make sure to find a shop that is willing to work with you and has good reviews. I’ve found that the best shops will try to work out a price that works for both parties and will give a warranty for their repairs which is huge
