Thank you for the video! I worked for a BMW dealership for 32 years, and I know the value of a nice how-to tutorial. You just never know what you might be getting into, thankfully this looks like a breeze.
For those who do not always need a working rear auxiliary heater. It is possible to replace the 2 heater hoses in the engine compartment with non-auxiliary heater hoses. These shorter hoses makes it much easier to work on the passenger side of the engine. This also lets you back flush both heater cores. once the engine work is completed you can restore the auxiliary heater hoses. good to replace those 20+ year old engine compartment heater hoses anyways.
Hands down, the most descriptive step by step video to get the job done. Just put the new one in my '02 today after watching. Thank you for making such a helpful video!
@@FixingWithPassion I need help with mine!! I just changed both actuators and the air is lukewarm (floor) and barely lukewarm roof vents! I have a 2003 expedition XLT, 4x4, 5.6lt
GREAT video, getting ready to tackle this in the next day or 2. Just confirming NO RADIATOR DRAIN needed? Just release pressure on overflow tank up front? THANKS MUCH!
Thanks for this. Quick question: I have a situation with this generation Expedition to where the front heater core will need to be bypassed but want to keep the rear. I'm sure this is not a big deal but would someone who knows more specifically about this comment?
Were both heaters intermittently working, or simply lacking heat all the time? My '03 Expedition sometimes works, and has plenty of heat, front & rear, but when first started, it's ice cold, even after engine is at operating temperature. Seems like air in the system, but having a devil of a time clearing it out, even using vacuum coolant fill. Maybe I'm doing it wrong...
That actuator on the side is for selecting cold air or hot air for the rear vents correct? Because the top one looks like it selects floor or roof I only ask because my buddies wife’s expedition blend door actuator is bad in the rear vents and stuck blowing heat wanted to make sure it was this one and not the one under the front dash any info would help so I don’t have to guess thank you!
My dealer tells me I need to replace the rear evaporator core. The front of the third row seat completely fell apart and the carpet in front of the seat behind the driver is also falling apart. Could this be from a problem with the rear evaporator core? I don't know what else might have caused the seat stitching to come apart as well as the problem with the carpet. Any ideas?
This is exactly what happens when you don’t put the proper coolant in these trucks. The problem is this they get low on coolant people put tap water in them it destroys the coolant system and heating systems. When all they had to do is pull into any automotive parts store and get a gallon jug of 50-50 that’s appropriate for their vehicle. Running the proper coolant in a vehicle saves thousands and thousands of dollars down the line.
I have a 2002 Explorer Eddie Bauer edition. I am planning on replacing the heater core just because it never has been replaced, but more importantly, the heater hose block that is under the SUV is leaking. I have already tried replacing the P trap looking hose down there, but the leak still persists. To replace that block do I need to do it from inside where you just exposed the heater core, or is this done from under the SUV??
Both of the heater cores is clogged on my 00 Ford Expedition front and rear. My question to anyone is can I just replace the rear heater core and have heat or would I have to replace both at the same time? The front is time consuming and rather pay a professional for that.
I did the front on my 2000 ford expedition. Yes it was hard! But was possible with 90 degree needle nose. Now my rears is not putting heat. Thinking draining or replace. Id rather drain. A bunch of sediment and rust flakes came out just the front.
