Okay so i have a 1995 Dodge Stealth r/t and my car was running fine no problems until last night i wanted to check if i was good on coolant cause the last time i checked was about 2-3 years ago when i put new coolant into the car. I took the radiator cap off and saw i was good at the full level. Then the next day im driving to the bank and turned the car off to get some money. Then once i went back to turn the car on i see my Temperature gauge start to slowly rise. Could i have maybe broken my Radiator cap while taking it off and now it cant hold pressure? I also replaced my thermostats as well when i put new coolant in 2-3 years ago. Anyone have any ideas what it could be?
