Would burping the cooling system be a good idea to start with & see how it does for 10min at idle?

Or should I just go ahead & drain all the coolant out, refill the radiator & over flow resevoir to full marker then replace the thermostat & see how it does for 10min at idle (burp system until bubbles are out)?

burp it first. then flush if that doesn't fix it. Replace the tstat if you gotta drain it

1. Pressure test the system, and see if it holds pressure, if don't then find the leak!!

DON'T GUESS!!

I was in a similar situation at one point with my d16z6. It was the start of a blown head gasket. i hope this isn't the issue.

Really don't think its a head gasket, it runs too good & my mechanic seems to think the HG is fine

The two main big hoses leading out in/out of the radiator should be the almost if not the same temp once the car has been wamed up and idling after a while. Check under the car where its been parked to see if you have any leaks or drips puddles. Inspect around the radiator cap, you might need to replace the cap if anything as well. But check the hoses where coolant is flowing. Check if the clamps are all tightening correctly. And when you refilling the coolant, make sure to squeeze the top hose occasionally as you pour coolant in the radiator. Next crank the car and run the heater on high after you closed the radiator cap, for a minute or two. Shut it off and fill more coolant if necessary.

You probably gotta replace the water pump. But ask your mechanic beforehand.
