Heater Core Removal

Sounds like you're talking about the heater control valve

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

two heater hoses going into the firewall
remove them and flush the heater core
you can run water and comp. air throw one side out the other and vice versa

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...

Your test method isn't accurate. There is no pressure pushing the coolant when you remove one heater hose. It is just as necessary to have some "pull" on one hose as it is to have the "push" on the other one. Instead, feel the hoses after the engine has been running a while. They should be too hot to hold onto for very long. If they're not, suspect the thermostat.

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

under the dash, yes it all has to come off, if you have no experience with vehicles take it in, expensive at a dealership about 5-7hours

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

Pull the rubber hoses off and connect them together with a tubing connector from the plumbing department of your local hardware store, or the "tee" from a cooling system flushing kit.

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.

Hi
Only thing I can think of would be the air duct to rear is not on or in place. Heat comes from front and taken into rear via air duct. Do you have optional rear A/C?

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.

Description Mitchel Manual has of your car is the warmed air travels to back not any water. Do you have hoses running to rear?

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?

Checked with a chrysler tech I know he said the same something about the BTU of core and aftermarket don't have enough? Asked if any trouble getting it to fit and did you insulate? Metal line is freon line to rear AC

I have a 1998 Dodge Durango V8 Magnum SLT 4x4
w/ 145105 miles. I smell antifreeze in the passenger cab and the engine does heat quickly. there is no leak but there was smoke coming inside the car through the vents. When I turn the a/c on it shoots hot air and also smells of antifreeze. I read the other Dodge Durango questions and see that it may possible be the heater core. I would like to buy the part first and then have a mechanic install. Which heater core make would fit my truck and approx how much should it cost to install to know if I am being over charged? I would install myself but have very little repair experience.
Thank you very much for any assistance

I would use either a factory heater core or a Modine. The labor guide calls for about 5.2 hours of labor , find out how much the shop charges per hour and go from there

Hello.
The rear upper unit is A/C ONLY, No heat. The rear heat comes from the rear console between the front seats. It is blown through tubes from the front under the front consloe. There is no rear heat blower per say, though you can direct the rear heat for mid, and lower console outlets, and of course off. Again, The rear upper is A/C ONLY.
And just to add. My A/C has never really blown cold, and my heat is NEVER hot! I'm thinking the heater core also. You repaced it yourself jeffs22? How was that?

You have to understand that a shop markes up the parts, and has to to stay in business. You wouldn't go to the ice cream shop and bring your own Ice cream would you? Plan on a 100% markup in addition to the labor and fluids.

Alos understnad getting a heater core job from the techs perspective is like getting dealt the queen of spades. It is a miserable job and no one wants it.

With the coolant loose the heater quality will go down
and not because the heater core is bad
you need to pressure check the system to locate the leak
some signs that heater core is bad and leaking
coolant loose
fog windshield when defrost on
sweet coolant smell
and if the heater core is to be changed I suggest have it done by qualified shop where they can evacuate the AC system in a environmental way
good luck

can I repalce the heater core myself?

Can't really answer that without knowing your experience level. Best I can do is post the replacement procedures and let you decide if you think you can perform this repair without damaging or harming anything/anyone..

REMOVAL & INSTALLATION


Disconnect the battery negative cable.
Remove the instrument panel from the vehicle.
If equipped with air conditioning, recover the refrigerant.
Disconnect the liquid line refrigerant line fitting from the evaporator inlet tube.
Ram: remove the accumulator.
Dakota, Durango: disconnect the accumulator inlet tube.
Drain the cooling system.
Disconnect the heater hoses from the heater core tubes.
Ram: remove the powertrain control module from the dash panel. Disconnecting wiring is not necessary.
Remove the four nuts from the heater–A/C mounting studs on the engine compartment side of the dash panel.
Remove the nut(s) that secure(s) the heater–A/C housing mounting brace to the stud(s) on the passenger compartment side of the dash board.
Pull the housing rearward far enough for the mounting studs and evaporator condensate drain tube to clear the dash panel holes.
Remove the housing from the vehicle.
Lift the heater core out of the housing.
Installation is the reverse of removal.
