Have you tried burping the radiator?

Usually you should not have to bleed the air out of the coolant system if everything is working properly. The coolant system automatically bleeds out the coolant system over time so unless you just recently changed the coolant or had air get into the coolant system you should be okay.

Did the heat fade over time or just suddenly quit giving heat?

Hey Chrissy.

The bleed screw will screw out all the way. But if functioning as it should, it will open after only being loosened. You should be able to loosen it and then fill the system until a steady stream of coolant comes out of it. You can put a piece of rubber hose over the end of the bleed screw to direct the flow and capture any released coolant if you want to.

If nothing comes out the bleed screw, you can just screw it out all the way and then fill until fluid comes out and then reinsert and tighten the screw while the coolant flows out. Of course, this is messy and you will lose some fluid in the process. The better plan is to replace the bleed screw. Many parts stores the US will have a universal replacement in the Dorman "Help" section. The same may be true where you live.

As far as checking for heat, I assume that at this point you have checked the blend door as we discussed in your other thread. And I know from your other thread that the temperature on the gauge runs right in the middle where it should, right? If so, and if assuring the system is full of coolant does not help, the next step is likely going to be to back-flush the heater core. As we discussed before, the 2004 PT's came with original HOAT antifreeze which was incompible with much of the older standard green antifreeze. If green antifreeze was added to the HOAT at some point in the past it may have created sludge in the cooling system. And that may clog the heater core. If none of the other things you try work, I would take the heater hoses loose and flush the heater core in both directions. I would also flush the rest of the system at the same time to help remove as much sludge as I can, if its present.

The 1.6 and 2.4 engines in their respective model chassis have their cooling systems designed to be self air bleeding.

The bleed valve on the thermostat housings of some model vehicles is primarily for bleeding after a cooling system flush and or coolant changes. Most vehicles still come factory equip with thermostats having a jiggle valve that helps control air in the cooling system. Some members have even made a mistake of trying to modify the thermostat drilling a hole in it damaging the thermostat. Unless you have enough air in the coolant system to have the engine going above the normal engine temperature I would suggest not attempting to remove the bleed valve at this time. Having coolant coming out of the bleed hole can spray onto belts and other components below causing more problems then what you have now.

How are you burping the radiator?

A180f thermostat would make the heater temperature around 100f opposed to 130f or more with a applicated 195f thermostat. Are you using a 195f thermostat?

If you can shortly after driving the Pt Cruiser feel the two heater hose lines near the fire wall. If they are still cold or just warm, you have a clog in the heater core. Remove the two lines as they connect to the metal tubing near the Cam sensor, don't remove them from the tubing near the fire wall as the cores are not meant to be tugged on or twisted trying to get the hoses off. Once you have the two heater lines disconnected at the side of the head use your garden hose to flush the heater core it self. Make sure you don't have more than 60 PSI pressure.

Hey Steve,

Chrissy has a 2.2 CRD engine.

Also, I don't believe you actually know what the temperature of the heater will be with respective thermostats. It's going to vary a whole lot with ambient air temperature along with other variables. I've warned you about getting information from that highly nefarious member by PM. As usual, he just makes up stuff and he doesn't care how it makes you look when you repeat it. But I care and it's not fair to you. The way I see it, you are a smart guy. Just stick to what you yourself know.

To add a little validity to my previous post about ptcruisersteve and/or NitroPT:

This is what Lynn posted in this thread (post #17) posted 02/18/15:

Water pump any to avoid ?

However all this good stuff on a daily driven PT cruiser may only be equal to most all the other brands? But if you want the better choice IMHO based on personal years experience selling and installing water pumps you will not go wrong with an AIRTEX.

nuff said!! ?
This is what Steve posted in this thread (post #4) posted 11/15/17:

Note any similarities because I sure do

I have also sent a PM to CREWZIN for him to check my IP address
Currently awaiting his reply

Maybe someone knows how it works on that engine?

Handy, I am sorry that you can't read. Let me help you. If you read my post I am referring to the 1.6 and 2.4 engine.

Are you a dictator telling other members what they can do and not do?

I am sorry but I have the impression most of the information you post comes from the internet. It has been proven several times on this forum. Why don't you follow your own advice.
