Overheating even after replacement of radiator, thermostat, and temp sensor.

You stated that you have an engine overheating problem. Appears, you may have a blowm head gasket.

The radiator has two fans upper one and lower one when AC on. The fans have two speeds one of them isnt working all the time. Just went through this took alot to figure it out. Good luck

I have the exact same problems it's not a head gasket because there's no water in the oil and my fans are working as well I had to replace a relay to get that working correctly what is happening in my case but I still don't have it fixed if I put coolant in and deleted so there's no bubbles at all work that day but after about 3 days or 50 miles starts to slowly overheat with the same problem when it's idling or sitting at a light when you move the temperature goes down because air is being blown over the radiator. What I've noticing is it's letting coolant into the reservoir but not pulling it back out when it needs it. when I check under the radiator cap after it gets to the point where I feel it needs fluid I open it up and it's empty down to the thermostat. I've done this a couple weeks now and can't figure it out I put a new radiator cap on but somebody said it might be the wrong radiator cap although I got it from O'Reilly's and told me it was the right one. Mine is a 2005 PT Cruiser no Turbo Mine is a 2005 PT Cruiser No Turbo I was also told that these cars have a bad design as it turns out and because the area for a radiator is so small If anything goes wrong it causes it to overheat I understand that but can't figure out what it is? If anyone has an answer to this and they've done it please let me / us know it's very frustrating because besides that everything works great and I didn't like the Pt Cruisers, But my girlfriend bought this one without me knowing and it runs great stuff for the damn ghost of the PT cruiser over heating problem???
