Still overheating after EVERYTHING has been done

110

Asked by Dec 27, 2010 at 03:52 PM about the 2000 Chrysler Sebring JX Convertible

Question type: Maintenance & Repair

I'm looking for help with my ghostship of a car. I have literally replaced everything in the heating/cooling system. Let me start from the beginning. My car has 133,000 miles on it and I bought it back in May but it hasn't run since July. She started overheating one day and it has been an issue ever since. We have replaced the thermostat/cap, put in a new radiater, replaced the water pump, put in new cylinder heads, bypassed the heater core, purged all the air out after putting in new parts...none of that has helped. The fans work and there is no oil in the coolant to suggest cracked head. After putting in the new radiater (2nd step), it ran good for 3 days and quit running again. It hasn't run since. BUT, you can idle her all day and she won't overheat. The second you start driving away, she runs way up in temperature. We are at a loss at this point. We need help! She's in mint condition (body-wise) to give up on her. She evens run smooth before she overheats.

I noticed you didnt mention replacing the temperature sending unit. Why wasn't that replaced, that shouldve been first on the list before expensive repairs.

but the car physically overheats. Could this unit cause the car to overheat somehow? Please explain.

Had similar issue with a 2001 Sebring LXi (2.7) and found ultimately that the thermostat had been installed backwards - YES it can be installed backwards!!! I reinstalled the thermostat correctly (bulb and spring towards the engine ) and it instantly ran fine!! Just passing on some hard-won information!

you need a Combustion Gas Leak Detector for Cylinder Head Gasket Check

Once you are confident your head gasket is leaking, head to your local AutoZone, NAPA, Advance Auto Parts, Car Quest, O’Reilly, or Bennett auto supply or Prime Automotive to pick up a bottle of BlueDevil Head Gasket Sealer or Pour-N-Go. BlueDevil Head Gasket Sealer is activated by the temperature differential at the leak point so it only is activated where there is a leak and will not clog or harm the rest of your cooling system. You can also purchase BlueDevil Head Gasket Sealer directly from BlueDevil here: Head Gasket Sealer
