Angry Overheating 2005 pt turbo

Hi i have a 2005 pt turbo overheating problem. We have replaced the thermostat,timing belt, cooling fan(fan assembly) and water pump and it still runs hot. My boyfriend says we should change the radiator but i dont think thats the problem. It is not loosing water either. I am out of options any help would be greatly appreciated. Thanks Marie

Have the head gasket tested & do a radiator pressure test.

Why don't you just do a flush of the coolant system? You may have some blockage in the radiator or heater core. Seems like you're going about solving the problem in a haphazard and expensive way (timing belt and water pump).

Does it overheat at low speeds or high speeds or both?

Does the radiator fan stay on when it starts to overheat?

Does the radiator fan come on automatically when you turn on the A/C with the engine cold?

Pressure test the radiator cap too. The springs get weak over time and the gaskets can develop a leak too. I'd just replace it for peace of mind. And make sure you check the rubber hose running from the inlet to the overflow jug. Sometimes they'll have a crack in them and suck air in, instead of coolant.

Even though most of the time you ought to be looking at the reservoir tank and filling it rather than opening up the radiator cap, if you are diagnosing overheat problems, you need to open that cap when the engine is cold every now and then to ensure it is "full to the brim". If it's not full, then either air was trapped in the system or it's getting into the system and not getting out to be replaced by the coolant in the reservoir.

Be sure to run the heater once in a while to make sure any air trapped in the heater core works its way out.

If the coolant is always up to the radiator cap, then the problem lies elsewhere.

We have tried everything even block seal and no luck s we having the head gasket replaced and having the head checked out. We did the block test and it came out fine also pressure tested the radiator. All or the test came out good so the head is the only other choice... thanks for all the tips.

It would have been nice to have helped if some of our questions had been answered.
