Overheating problems
A couple of weeks ago my car started overheating. It turned out to be a bad engine coolant filler neck and cap. I replaced both those. Then it started starting really crappy like stalling out right after i started it and puttering alot. I figured with it overheating although i was watching and putting coolant in it before i replaced the neck and cap it was probably the ect sensor. So i replaced that. Now it still starts funny occasionally and my heater takes forever to warm up. and the driver side vent gets hot at least 10 minutes before the passenger. And the overheating light will flicker occasionally but coolant is always full and it never feels hot. I checked the oil for a blown head gasket and the oil looks brand new as i just got an oil change. There's no coolant in my car on the floor so i don't think it's a heater core issue. Any help would be greatly appreciated. I don't know what else it could be. It's a 08 yaris hatchback. Only things I've ever replaced was the alternator maybe 6 months ago and the water pump maybe a year ago. It's got 240000 miles on it.

Where do all these recent thermostat failures come from? :D
I'd check that. |

Make sure the system is purged of air. A large trapped air bubble could cause that behavior.

After reading this actually sounds like my problem. I just jack up the car take the radiator cap off remove what coolant is in there and start the car and set the heat on high? From what i read.

There is also a small petcock on the back side of the block that you are supposed to open when you initially add fluid to a drained system. If you open that now quite a bit will drain, as it is only about half way up the block, but opening that for a few seconds may help burp it.

Didn't seem to fix what I can add is, it seems my reserve stays full but the engine coolant neck loses what I put in it and gets no more. Like this morning it was empty but reserve was full and it was still overheating. So I waited for it to cool down and poured it straight in the radiator cap and it's fine.

Also, remove the oil filler cap and see if there is any foaminess on the bottom of it.
