Question 01' pt help please

Hello everyone,
im new to this site and it seems like everyone here is pretty knowledgeable about pt's ..and well im having a bit of an issue, my wifes 01 pt used to overheat ive fixed that twice first it was a dead cooling fan motor. Fixed. Then just recently water pump started leaking. Fixed. Well when i was trying to figure it out i did the easy stuff first. Temp sensor and thermostat. My first mistake was using a failsafe thermostat because the next time it overheated, stuck wide open. I forgot about it until it got cold. Naturally. So i just changed out the thermostat yesterday for a standard 195 degree and while just sitting warmed up nicely. Went to drive it home later yesterday evening and it never warmed up. Although i did get a little heat from the vents just not much. And the only logical thing i can think of next is dirty heater core?
Any insight would be awesome

Is the temp gauge in the middle? If so, you have a heater core problem.

Question Re: 01' pt help please

Couple of questions:

When the car starts to overheat,does turning the climate control from 'cold' to 'hot' change the reading on the temp. gauge?

Have you made sure to bleed all air from the cooling system?

The car no longer overheats it doesnt heat up. The needle stays cold unless you let the car sit and idle.

That may be your issue. A half full cooling system may keep the engine from overheating on a cool day. But it often doesn't allow the heater core to warm up.

You won't get any heat until temp is halfway.

Leave heat on full and run the car - air will eventually work itself out - when car is cold, take of radiator cap and be sure coolant is up to the brim.

any update to this? I just took mine in to the dealer and they say everything is fine. sure, it's -8 outside, but the internal engine heat should still register halfway on the dial. doesn't heat up even when 30 or 40 degrees outside. while idling, temperature will rise, but when going down the road temperature gauge drops to the bottom and heat is almost gone.

could the sensor be bad?

I had the same issue when I installed a Stant Superstat thermostat. But after putting in a standard thermostat, the temp stays right in the middle on the gauge even this morning when it was 9 degrees.
