Usually not that hard on an older GM. locate approx location of heater core by looking for two matching size water lines that enter the passenger compartment thru the firewall from the engine compartment. go inside under dash and look for the heater core box. remove screw to open and expose the heater core

I need a diagram of where the heater core is in the engine and the easiest way to replace the heater core.

Heater core replacement is delicate and it is very easy to damage hard to get parts, including the core itself. This job may be best for a shop to handle. The heater core is located in the heater box, follow the heater hoses from the engine to the passenger side firewall area...

Heater blows cold air no heat

There are three thing that can go wrong here. I will give you the two simple ones first. first, check to make sure the thermostat isn't sticking or stuck. if it is, change it. two, Hot coolant going from the engine to the heater core, is controlled by a valve at the engine(these do go bad). Check the line when the engine is warmed up by turning on the heater(I know), and feel the line after about 5 minutes. The line should get hot, or very warm. The third is your heater core is clogged and needs to be replaced. hope this helps you

Replacing a heater core in a ford expadition

Replacing this heater core is not fun, the entire dash must be removed and the a/c drained, this is so you can access the environmental station and remove it from the truck, then you can change the heater core, if you are not comfortable with this level of work I suggest a good local repair shop. I also recommend factory replacement heater core, the aftermarket heater core connection pipes are sealed with an o-ring and compression, the factory original is solidered completely, if you are going that far you may as well put in something that is solid, not pressed. Hope this helps, let me know.

Is there instructions somewere on replacing a heater core on 2000 Jeep Larado

You have to remove the console, put the steering column down, remove the complete dash to access the hvac assembly where reside heater core, blower fan, blend door(s) and recirculate door.

Around 15 hours of labour time by experimented person, plus the cost of defective parts.

If you're planning or thinking to do it yourself, I will suggest that you take a look on the following youtube accelarated video which give you an idea.

As you can see, it's an heavy process. So be sure you heater core is really the root cause of your problem (leaking? odor? etc...)
If you're not sure and experiencing heating problem could be also blending door, recirculate door, heater control valve, bad t-stat, incorrect cooling liquid level and so on...
Hope it will help
