Disconnect the negative battery cable. Drain the engine coolant into a clean container for reuse. Raise and safely support the vehicle. Remove the rear lateral transaxle strut mount, if necessary. Remove the drain tube and disconnect the heater hoses from the core tubes, lower the vehicle. Remove the sound insulators, console extensions and/or steering column filler, as required. remove the floor console outlet ductwork and hoses. remove the heater core cover. Remove the heater core mounting clamps and remove the heater core. This information was taken from chiltons auto repair manual. So good luck and hope it works out

From what I understand from an independent mechanic it is about $600.00 and rather involved.

how hard is it to replace the heater core in a jeep liberty limated editon step by step instructions

how hard is it to replace a heater core on a 87 325e BMW 2 dr? thank you in advance.

To change the heater core on a Chevy Celebrity: 1. Drain the coolant below the level of the heater core into a suitable container. 2. Under the hood remove the heater hoses from the heater core. Remove and save the two insulators and save for reuse. 3. Inside the car the heater core is behind the heater ducting on the passenger side below the glove box. 4. There are two covers that have to come off. One is a small cover on the right hand side of the main duct. It is held on with three screws one of which is hard to see. It is also held on with a sealant that makes it a tad hard to remove even with the screws out. 5. The larger cover is held on with a series of screws and clips. Remove them and take the larger cover off. 6. The heater core is held in place by two strap clamps, remove them and the heater core should pull out. Reverse the steps to install the new heater core. Refill with coolant and check for leaks.

Sometimes changing a heater core can be a very big job. It is not changing the core that is hard, rather getting to it. Good luck.

it's not that hard you just need to have pictures to guide you through it. i did my wife's heater core in 87 t-bird. Take the entire console out of the car to facilitate removal of nearly all of the dash Most of the dash will have to come apart to change heater core Also the air ducts air box as affected Better just to bypass the bad core under the hood to return the hot water back to the engine and just leave the bad heater core alone Use a shop vac to suck remaining water from the bad heater core At a shop the change of the heater core costs from 300 to 400 dollars because of all of the labor

Very hard.............. You will need to discharge the a/c system, pull back the dash and remove the complete a/c and heating box to remove the heater core.........

No! Why there's one right over there!

I found it helpful to get a repair manual for $15.00 at the local auto store.If you never changed a heater core on a 93 jimmy its very time consuming you have to pull the dash forward to get the heater core out that entails quite a bit of labor but its not hard just time consuming.The $15.00 you pay for a repair manual is worth saving hundreds of dollars in labor they want to fix your heater core at a garage.Good Luck!

I recently installed a new heater core in a 1991 G10 van. I removed the heater fan housing, the heater core hoses, then the compartment came out. After removing the campartment has to be taken apart to replace the core. Alot of work but not all that hard.

Pretty difficult you will more than likely take have to take the whole dash out... It will be an all day job

Remove the heater-A/C housing from the vehicle. Refer to Housing Assembly HVAC/ Service and Repair/ Procedures. Remove the screws and retainers that secure the heater core to the heater-A/C housing. Lift the heater core straight up and out of the heater-A/C housing. INSTALLATION Lower the heater core into the heater-A/C housing. Position the retainers over the heater core tubes. Install and tighten the screws that secure the heater core and retainers to the heater-A/C housing. Tighten the screws to 2.2 Nm (20 in. lbs.) . Reinstall the heater-A/C housing in the vehicle Refer to Housing Assembly HVAC/ Service and Repair/ Procedures.

It IS a bit of a pain in the $#&(... You have to pull the plastic shroud that is around the heater box under the dash so that you can expose the heater core. ONLY THEN, after the heater core is exposed do you go under the hood and pull the heater hoses and the three or 4 nuts that hold the heater core in place. But the plastic shroud is the difficult part. You might want to see if you can locate a set of dagrams.

took me about 2 days, you have to remove the dash completely to get the heater core out. I suggest paying to have it done. I sure will if it ever happens again

There are several reasons why this might occur. If your fluid level is low, your engine will not circulate enough antifreeze to fill your heater core ( which usually leads to your engine overheating, but not always if you are just borderline low), if your heater core is plugged (most common) or if you have a sealed system and there is air in the system which prevents your liquidfrom running through the heater core. The most likely cause is a bad heater core which is bad news because it is hard to access, therefor hard to replace.

its hard you have to take the whole dash out to reach it i had a camaro and it was b****

The heater blower motor will most likely be located under the dash by the heater core assmebly, but first you need to be sure that that's the problem, it could just be wiring to the blower motor. Shouldnt be too hard to replace, and should be simple to find,

Very. Requires removal of the dash for access.

Simply disconnect the heater hoses going to and from the heater, (Inlet & Outlet) at the firewall. Purchase the proper size hose coupling that will allow you to connect the 2 hoses together. Do not plug these hoses, just connect them together. The coolant will now not flow through the heater core.

It's basically behind the radio inside the cab. This is what you do: 1 Drain the coolant. 2 Disconnect the negative battery cable. 3 Disconnect the heater hoses at the fire- wall 4 Working in the interior, remove the radio, if equipped 5 Disconnect the control cables from the heater unit assembly. 6 Remove the air flow ducts from the sides of the heater unit assembly. 7 Remove any electrical connectors and vacuum lines. 8 Remove the four heater unit assembly mounting screws and pull the unit out 9 Once removed, the heater core can be detached from the heater unit assembly 10 If the heater unit assembly must be dis- assembled in order to reach the heater core, disconnect the rod from the swivel joint and the cold position lever control. Remove the screws that retain the heater core cover and remove the heater core. Note: During reassembly, the control rods must be adjusted.
