Heater Core Removal

How do you install a heater core?

Duh, I thought you would tell me.

Where is the heater core located on this vehicle?
Is there a valve that controls the hot water flow to the core? If so where is that?
There is minimal heat comming from the heater. I have replaced the thermostate twice. The water pump and fan clutch and cleaned the radiator. The truck does not overheat or leak/use water. Any ideas?
Thank you

Heater core located in with the ac evaporator on the right side of the dash/firewall.

I'd try flushing it first. Check the flow thru the core. There is a valve under the dash that has a butterfly in it. You'll have to disassemble the dash to get at it.

Very low coolant flow through the heater core(i disconnected the heater core discharge and started the engine.)When I ran the garden house through it the flow was excellent. I'm looking for a "try next". Maybe a clog in the hoses? Water pump? New belt? Thermostat and coolant level are good btw.

Ok that makes sense. The inlet hose to the heater core gets hotter than the outlet hose. Neither one gets as hot or close to as hot to the radiator house.

Where is the heater core located on a 2000 dodge durango 5.9 4x4 I tried to look it up but no luck

I was wondering if I could somehow disconnected where I don't have heater or AC so we don't have it leaking anymore.
I do not have the money to replace it at the time

Recently I replaced the heater core using a new core from AutoZone. It was larger than the the $225 one from the Dodge dealer but only cost around $30.

The heat to the rear now comes out very cold and the front comes out hot.

Any help would be greatly appreciated. As you know this was a long tedious job.

Yes, there is the optional rear a/c. The problem seems to be that the water circulates through the heater but does not have the pressure to reach the rear which is an uphill run.

The dealer told us that we must use the OEM part not the aftermarket part. The aftermarket part is not the low-profile type that came out of the car and the design looks different. Auto Zone states that this heater core will work and the size difference is just a slight inconvenience when installing.

Please let me know if you need more info or if you have heard of this problem before.

There is an aluminum line that goes to the back heater A/C. It looks to me like there is a seperate heater unit in the back of the car (on top).

I beleive they require different pressure for the front and rear but from the same heater core.

It worked fine with the original part but not the Auto Zone Heater Core.

Is this something you are familiar with?
