I have a 2002 Ford Escort ZX2. It only blows cold air when the heater is turned on. I am assuming since it is blowing air, it must be something with the heater core. I hear this is a pretty big job and...


Low coolant will cause this issue as well. You can check the heater core by letting the engine warm up and then feel the hoses going into the heater core to see if they are hot. If they are both hot, then you have circulation to the core. Another cause, besides low coolant, could be the trap door that shunts air from the core to the vents could be stuck. If you do have to replace the core, you have to remove the dash from the car to do so.

I need to replace the heater core on my Escort...where is it located and I could use a diagram on replacing it...thanks Edd


First Edd does you're escort have air conditioning, if it does you will have to find a shop that will discharge the a/c system for you. Plus I would recommend getting a manual first, Fords are known for having to pull dashes loose which can be a challenging job, For some a couple of days, for experienced technicians several hours. So please read what you will need to do to access the core before you start, and have plenty of patience and a good set of quarter drive sockets and extensions. The heater core is under the dash in the center or right of center, look outside the firewall where the hoses enter will give you a good idea. If you don't have A/C it will be easier. Also if you have to deal with moving the dash very much do so in a warm garage not out in the cold or you may have some cracks in the plastic of the dash that you hadn't before. Follow the steps outlined and use some sort of lubricant to install your heater hoses, and new core can be damaged pushing on hoses, and if you use screw type clamps don't overtighten and then check them again in a few days and retighten as necessary.

I have a water leak on the passenger seat from my ford escort 1999 ac


One of two things have happened. Either the AC drain is clogged and condensation water is leaking into the passenger comparment or.... the notorious ford escort heater core is leaking. (I had an escort for 7 years and changed the heater core 2 times. Metal core with plastic end caps. Both of mine leaked at a corner of the end cap. Not a fun job to swap out a heater core either......

Need more detailed Instruction on how to replace heater core


Answer
Once again you have an ALL DAY JOB ahead of you. YES, You have to remove the "whole dash".

However, Sometimes you can get LUCKY and only unbolt it without pulling all the wires and cables and junk and it will come back just far enough to be able to remove the heater box.

NOTE: I have found that on SOME Ford models.,:

They install the heater core in the interior plastic housing and mount it on the firewall with the studs protruding thru the firewall then they put on the NUTS from the engine compartment side onto the bolts to hold the assembly onto the firewall.

Then when they mount the engine compartment housing OVER these same studs that protrude thru the firewall and then they install a SECOND NUT to hold the firewall compartment on.

So you have 2 nuts on the same bolt. Therefore you have to take the engine compartment side housing side off FIRST and then you will see the set of NUTS that hold the interior housing onto the firewall,

Heater core


sorry to say, but the car at best is only worth about $1100. Most likely more like $800. A professional heater core will cost $600 to install. This is a very-very-VERY big job to do yourself...if you never done one. I say, take the $600 you would have to spend, sell the car for $300-$400 needing a core, and buy something else with that money. No offense, just the reality of the situation. Sometimes you need someone to just say it.
