my car I can be sitting in a drive-through or in a parking lot turn the AC on and run it for hours and it's okay it never goes past 4 but as soon as I start to drive it goes up to 6 almost to where the lights that's going on telling me it's going to overheat I have burped it! I have tried to flush it? I don't know what's wrong with it. Any advice would be greatly appreciated thanks in advance... It's got 119,000 on it and I make my living off driving my car. It's been great until this proublem. I got it used and it had 102,000 miles on it whenever I got it July 2019. will be a year I've had it.... Gets oil changes regular but I don't have any warranty on it? In I don't wanna take it to the dealership? It Will be$300 for them to look at it. If I can figure the proublem, I'll fix it myself but any other have this proublem n how was u able to fix it?
