IT sounds like that is the problem. Replacing it is an involved process. I strongly recommend purchasing a repair manual that probvides step by step instructions and pictures to identify parts. For me to try and explaine it via the internet allows to much room for error.

Take off the dash steering wheel all that good stuff and you will see the air ducts. There will be a removable panel which hoses the heater core!

When I accelerate I can hear a gurgling noise on the passenger side under the dash. I do not think it is the heater core because the heating works fine, I do not smell antifreeze and I do not see any antifreeze. Any advice on what I need to check or replace will be greatly appreciated.

Take care,

David Thompson

99% of the time gurgling means low coolant and air in the cooling system, the gurgling is the air traveling through the heater core. Check the coolant level on the engine when cold and top everything to the cold levels. Start the truck and let it warm up. Check the overflow reservoir once it is up to temperature. Shut it off and watch the level, it should drop as the coolant contracts as it cools. If the level stays the same replace the radiator cap. It is not allowing the system to operate properly.

If the hose fitting breaks can you just replace the plastic fitting or do you need to change the whole heatrer core?

Hi:
If you are refering to the fitting that is integral to the heater core, if broken replace the entire core.

Probable causes: could be a heater control valve, air mix/blend/mode door problems, vacuum and actuators and the HVAC control module.
