Question about Jeep Cherokee

1 Answer

I need to replace the heater core in my 1999 Jeep grand Cherokee with the 4.7L engine. I just can't bring myself to pay the 1000.00 for a shop to do the work. I'm a shade tree mechanic. I have worked on all kinds of trucks and Hot rods but the newer cars are a pain in the a**. Is this something I can do at home? I have lots of tools.

    Disconnecting the A/C, evacuating, and recharging is not a problem. I have all the equipment.

    Thanks for the advise. I know it's a big pain but it's a matter or principle. I'm not going to give some guy a grand for doing something that I can do myself. (even though it will take me twice as long and cost me 2 grand)

    Yes, this was helpful. I don't need to continue on this any further.
    Thanks

Hello Jdarstvac.

This is a fairly big job. Book time is 6 hours for an experienced mechanic with proper equipment.
I looked in the service manual and it is several pages long, too much for me to send here.
If you decide to undertake the job, get a proper service manual. One from the dealer or subscribe to All Data on line.
You will need to get the air conditioning system evacuated and recharged as the AC system needs to be disconnected to remove the heater box.
You could probably do it given enough time. Take pictures as you remove items so you know where the parts are when reinstalling.
Good luck with the job.

Thank you for using FixYa.

    It appears you are well equipped J.
    If you have tools such as those and have the know how, go for it!
    The job is such a pain, lots of screws and hardware, hoses and wires.
    And a lot of it done upside down on your back.
    I'm getting too old for that stuff, Ha!

How do i replace/install a heater core for a 1999 limited edition jeep cherokee 4.0 liter 6cyclinder


I would make sure the core is the problem. You may have a heater control valve that cuts off flow to the core by vac. or a blend door that cuts off air flow thru the core.
You will need a shop manual to replace the core. The dash and console have to come out, along with discharging the ac.

I need help with heater core replacement for my 1999 jeep grand cherokee laredo


Changing the heater core requires complete removal of the dash panel and plenum box. To do this you have to remove the steering wheel, steering column, evacuate and recharge the refrigerant system and drain the radiator. I would only consider changing the heater core if it is physically leaking into the passenger compartment. If the problem is heat transfer to the HVAC system only, the problem is more likely with the blend doors. Check heatertreater.net for pictures and diagnostic information.

I suggest review the ZJSecc24-Heating-and-Air-Conditioning

First you'll need remove the heater A/C unit from the vehicle; after, remove the heater core retaining screws, and finally, pull the heatrer core straight out of the housing.

Hop helped with this (remember rated this help) Good luck.

How do i get to the heater core to replace it?


It is a big job. I did this on my carport about 6 months ago. It is an all day job because you have to take every part of the dash down to the firewall. Be carefull when installing the new on because the work area is tight and the cores are brittle. Try www.wjjeeps.com

Heater blows cold air when idle


Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.
