No you do not have to get under the car to burp it, it really quite simple.

Run the car till it reaches temperature, like go for a 5 to 10 minute drive. Come back and park as I said , let the HHR cool off for a few hours, open the rad hose cap, top off the Dexcool, this can take a few tries. Start up the HHR with the cap off and see if the Dexcool goes down then top it up. Put the cap back on, tighten it up.
Check the Dexcool again next morning.

And keep monitoring the coolant level, I would say every morning for 2 weeks.

Now what about the cooling fan?
