2000 Lincoln Navigator, How do you get the heater core out?

I have attached a link to assist you in the replacement. https://itstillruns.com/how-to-replace-the-heater-core-in-a-lincoln-navigator-12143658.html

check the heater control on the heater hose inlet and return. it may be blocked or it needs to be replaced the heater core might be defective

Here's a link to the heater core.

good old Ford Lincoln and mercury s don't know of single one you don't have to remove the complete dash to replace heater core

Far as trying to find re assembly diagrams that going to be hard to find if they even exist try calling Ford dealer ask for parts and they might be able to print you one out if they have one (they usually don't charge for this) if they don't have one good luck finding one because they probably aren't any

Not much else. It is almost definately the heater core. The brownish stuff is rust. It may not be leaking bad enough to soak the floor yet, but it will.

you have a heater core leak. If you start seeing coolant on the passenger side floor, that is another dead giveaway. This is not any easy replacement, you will have to remove the entire dashboard. Heater cores are pretty cheap though, the last one i bought was for a dodge, it was $35.00. I hope this helps.

You must remove the entire dash from the car to access the heater core. Watch the attached video. https://itstillruns.com/how-to-replace-the-heater-core-in-a-lincoln-navigator-12143658.html

it sounds like the heater core hoses or even the heater core it self, you must use a small mirror to see where it is coming from in order to properly fix problem.,

Iv'e done just about everything anyone can do on a car (a few times more than once)..and, heater cores are not my favorite job! Good luck!!

U must remove the entire dash assembly and then the heater core housing which is part of the air distribution box, time to do the job 10-15 hours.
