I have a 2008 Chrysler 300 and it is overheating. I have replaced the radiator cap and released the air with the bleeder valve when adding coolant. coolant gets trapped in my overflow then overheats.

Question type: Maintenance & Repair

I have not replaced the thermostat or anything like that. I don't know what else would
cause the water to back up into the overflow.

Turn your heat on. If it doesn't work, its probably your thermostat

I have turned on the heat it does work very well. I'm think maybe my cooling system is blocked but i would like to be sure.

Does the over flow tank have a cap on it to add anti freeze ?

I does have a cap, and i have added antifreeze.

Water pump,

I haven't seen any leaks would it still be the water pump? It takes a few days after I bleed it air before it overheats again.

Instead of bleeding with screw bleed like this. Remove cap from over flow tank and fill with anti freeze to full mark, leave cap off and start vehicle and let idle, once vehicle starts to reach operating temperature thermostat will start to open, anti freeze level in tank will drop, add more anti freeze to full mark and put cap back on. All air will be removed unless there is another problem.

You should also do a cooling system flush. Prestone Super Flush is really good.

Thank you guys. I will work on this and let everyone know.

Try your coolant reservoir cap I have a 08 Chrysler 300C that has a hundred 2000 miles on it mine done the same thing the temperature gauge showed no signs of overheating nor did the motor I did a compression test to make sure and other tests I replace the thermostat before the coolant cap did not fix it after replacing the coolant cap driving get through months later I've had no issues hope this helps

Also after replacing the coolant cap on the reservoir make sure you do bleed it it wouldn't hurt to take the reservoir off and clean it out good while the engine is cool have a blessed day
