Customer Question

I had a pre purchase inspection of a 2007 PT Cruiser. The auto shop where I had the inspection had high marks/ratings. The inspection just came back with a lot of catch up with routine maintenance.
I get the oil changed, and then hit the road.
I purchase the car, and then drive it 50 miles, then when I get off the freeway the Radiator Reservoir starting boiling. While I was waiting for it to cool, the oil stick was showing plenty of fluid. I pulled over and stopped to let it cool down for a bit, until I moved another few more miles where I stopped for the night. I went to purchase BARS head gasket sealer. I used half as instructed by the product, completed the instructions and stopped for the night.
I came back today with a new radiator cap, and radiator additive to lower the temperature, and added antifreeze. I drove the car 50 plus miles no over heating, and ran just fine. Could part of my issue been the defective radiator cap, and low coolant?

Once completed above while the car was warm, I tested the upper radiator hose. I was about to hold it without my hand/fingers getting warm for about 5 seconds. Could this be a thermostat issue?

Hello, my name is***** you for the question. It does sound like it may be a bad thermostat. if it is not opening at the right temperature this will occur. If it is losing coolant then it needs to be inspected for a leak. If it is leaking or burning coolant then that needs to be addressed first. If not then it may have lost coolant if it was boiling over. I would replace the thermostat first to see if that takes care of it. If not then a block test needs to be done to see if it has a head gasket issue, which is very common on this engine. I hope this helps. Please let me know if you need further assistance.
