could you please tell me where the coolant reservoir is located in my 2006 hummer3
Should be a clear bottle. I think it's near the firewall on the driverside.
Tom is right, and beware, it's one of those pressurized reservoirs, do not open hot. Unless empty, but still be careful There is no radiator cap.
