Overheated due to Cooper stop leak

Asked by Family May 05, 2020 at 02:28 PM about the 2006 Chrysler Sebring Touring Sedan FWD

Question type: Maintenance & Repair

So my Chrysler Sebring over heated  yesterday and was able to drive it home.
Funny think this the temp gauge jumped up to 3quareters on the temp gauge
then just dropped to right above the halfway point. Made it home wich was
about 2miles away from were I broke down at. Now when I first bought the car
about a year ago It had an overheating issue so replaced radiator issues
stopped. But before I replaced it I tried putting in that small jar of Cooper stop
leak because  top of raideator was leaking.. But u have to put  it through the
overflow tank? And that didn't work so maybe that Cooper fucked up the
overflow tank and that's why these issues occurred.??

Please refrain from using profanity! Most likely the stop leak product worked it's way into the cooling system passages and has restricted the flow of coolant. Flush out the cooling system using a chemical cleaner to get rid of the stop leak product, refill the cooling system, and check for leaks. If you continue to overheat pay attention to when the overheating occurs. If you overheat when driving it's a coolant circulation problem such as a bad water pump, stuck thermostat, or (still) clogged cooling system passages in the engine. If you overheat when at idle or slow speed driving it's an airflow problem. The cooling fans are not working, the front of the radiator is clogged with dirt, leaves, or other debris. Hope that helps!

Maybe it overheated due to low coolant level.
