Exclamation Boiling and Bubbling OVERHEATING Still.

After checking everything I know in my limited knowledge, My 02 PT is still overheating. 144,000 miles. I have replaced: Radiator, Water pump (and timing belt), fan, thermostat, radiator cap and checked to ensure the fan is kicking on. I am inclined to think itís the head. Any thoughts, tips, or tricks? Thanks

Gotta agree with cruserdad. If air gets in the system the boiling point of the coolant drops way down. It's supposed to be a closed system with no air which alows coolant to go back and forth between the radiator and the overflow tank. Air in the system stops that transfer.

I have a head for sale!

But they are very good pieces, rare to see problems.
Would you mean headgasket?
Much more likely.

There is a bleeder on the water outlet neck.

welcome to the site, greetings from San Antonio from Eve and I.
Sorry to hear about your prob. Are you using HOAT coolant? Is there white smoke coming out of your tail pipe?

This happened to me, it was the head gasket, exhaust gases were getting into the coolant. I tried everthing before admitting the gasket had gone.
IMO an air lock would not cause the bubbling, as you need gas getting into the coolant constantly to produce the repeated and often violent surge of bubbles that purges through the system. I also read somewhere that the system is self bleeding as long as you follow the coolant replacement method properly i.e. any little air that remains will make its own way out during the first few heating/cooling cycles.

When manufacturers came out with ball joints and knuckles that didn't need lubrication they did away with the grease fittings. If the PT was self bleeding, why did they add a bleed screw? ...and it does work!

QFT


That bleeder facilitates refill, just voids under thermostat, not the head per se.
Thermostat has either a hole, or a 'jiggler' to bleed vapor / air.

He'd have to leave it open during operation which would void the coolant
also, but the thermostat is already open

There's a headgasket How-to with pics I'm working on- get the FSM from
someone, it's not impossible

well then try this drive it to make sure it still is bubbling and over heating then bleed it that is a simple 5 minute job and see what works you really have nothing to loose
