The wifes car has been having a weird issue lately. She was on the phone the other day pulling into a parking spot when her car chimed at her to tell her "shutting AC off due to overheating" or something along those lines on the dash. She looked and realized the temp gauge was pretty high and shut the car down. She gave me a call and i told her to buy a gallon of water and pour it in the overflow tank (since it was empty). Then told her to turn the heat on high and head home and watch the gauge.
She made it home and we looked at the reservoir again, it was low/empty. filled it up and the gauge seems to be staying in the normal range the last day or 2. No water in the oil and no leaks that we know of. Pulled the cap off the radiator and found some burnt or brown dexcool on the cap and inside the radiator neck. I gave the car a flush maybe 2 or 3 years ago.
Intake gasket time? anyhelp? its an 05 3800 with about 125000 miles
