Real easy to change. Just take the lid, bellow, and throttle body off. You will have perfect access to it, should be straight forward.

Not a difficult job, messy, but not difficult. Change your belt and tensioner at the same time while you are there. Coolant on the belt often makes them slip and OEM tensioners are poopoo. Get a GM pump.

IF you decide to have a shop do it, there is one reason in my mind:
Warranty.
A Chevy dealer will offer lifetime parts AND labor warranty on this repair. If you are short on time, don't want to mess with it, or want peace of mind for the long haul - do it. I did this for most all of the lifetime parts (alternators, A/C Comp, O2s, etc) and it's paid off for me BIG time. One less thing to worry about.

Two questions to ask/reconcile to make this decision in an educated fashion:
1. What is your time worth?
2. Do you enjoy wrenching on the car enough to offset downtime related to question 1?

But how much will they charge you the first time to change it? Probably enough so even if you come back they'll still make money.

When did GM start offering Lifetime warranty on parts & labor for repairs?

I know they always had 1 year, 12,000 miles warranty at the dealership, but Lifetime???

I just did mine.
https://ls1tech.com/forums/general-maintenance-repairs/895257-changing-water-pump-thermostat-use.html

Easy and straightforward, the hardest part was getting the hose off the thermostat. If you haven't already done them, now is the perfect time for some free mods like I did.
