Just removed mine today, did a complete flush of my core, had zero heat. Guess it doesn't take much to block these cores because it didn't seem super blocked. After reassembling I am back to full heat. 2014 Jetta 130k km. Thanks for your video. If amyone else is considering trying this. If you are a manual person, super easy to do. I removed the 2 rubber hoses from the engine side, then removed my lower clamp. Caught the antifreeze with a bag instead.
My hoses wouldn't come off the heater core. I found a 6mm nut between the hoses, at the firewall in the engine bay that holds the hoses to the firewall. I loosened it, gave it a good wiggle and that gave me just enough room to pry the hoses off the heater core.
I did mine today. Quick and easy job I put down diapers and some towels. I did not remove the lines at the firewall in the engine bay. I did not remove the lower dash panel. I decided to take some pliers with my torx bit to remove the one screw that holds the heating duct.
2014 vw passat tdi se (diesel). replaced my heater core still no heat. car runs great no overheating or signs of bad thermostat (unless stuck open). Anything else that might not cause heat?
does your A/C work? could be a possible bad blend door actuator. switch the temperature control from the coldest it can go to the hottest it can go. Be quiet and listen for a movement in the dash. When you switch between heat and cold a door moves that changes what goes through the vent.
@@cooldude639jj I have heat now think it was heater core after a while of driving and burping the left over air out. This after I flushed system replaced core and put in pink coolant I now have heat.
Check your EGR performance and log your exhaust temps. If they’re running high it could be an issue with your EGR which if I remember correctly flows directly into the heater core
@@AA-gl1dr I did get code for egr cooler a efficiency below threshold this was before I replaced core, just checked with blue driver code reader it not showing up any longer yet I suspect the egr cooler should probably be replaced some time I don’t know where it is I’m new to Volkswagen used to mustangs
@@turgeo2004 fairly certain you gotta drop the subframe to get to it. Clogged heater core is what made my EGR cooler die and killed a head gasket causing it to burn acrid white smoke. I’d definitely look into the EGR/DPF delete but that can get spendy.
On this application, the passageways are really small. That makes it harder to flush out. Compared to other cars, it’s very cheap and simple to replace.
I broke it! I dont know what its called but basically it controls whether the fan blows hot or cold air. Now i have to manually turn that lever to turn on my heat and it resets every time you turn off the car. Gonna go get it checked out this week.
Levkin ... so that when you remove the lines at the heater core the coolant doesn't keep flowing inside the car. makes a huge or bigger mess. Plus, it allows those lines to the heater core to move just enough to help in the removal and install of new heater core.
@@robertbrown7466 ... YES, the nut/bolt is on the engine side of the firewall. Loosen or remove so the metal hoses can be pushed in/out. Just be cautious that you do not rip the rubber grommet at the firewall that the connections are made. Hope this helps.

Did you replace yours?
That looks very easy thanks for the video Brandon
No problem

FYI. Make sure you use the original Volkswagen clamps. You will probably develop a leak using the aftermarket clamps.
Does not removing the hoses make a huge difference?
Did you flush the system? And how’s your heat working a year later?
Nice job.
Thx.
Np. Hope it was helpful
Where are you bought the new one
Good job
How many of you guys dropped that tiny Allen screw on the bottom coolant line behind the carpet to forever be lost
Is Audi a3 2009 same
thanks brother great vid did you replace the pipes or you dont need to just put on new gaskets?
No need to replace metal pipes. New gaskets will be just fine.
great video, you just saved me some money. But how did you remove the lower dash to get better clearance of that foot vent? is it easy?
I didn’t remove the lower dash. Just the vent that was held in by a couple t20 screws.
If your car does have the lower cover, it's just a couple screws, and then it pulls down and towards the seat.
Did you remove a cover underneath the car? Cause I don't see clearance from the firewall hoses to the ground to drain down to.
No I didn’t. But I lost my shields the first winter I had my car

Thanks for sharing. Are the 06-2011's about the same? - take care from TN
I’m sure it’s different because the interior is different.
@@djbranboogy03 Thanks man. - take care
So it's about a 2hr job? Can the core just be flushed out? Why does it have to be replaced? Or removed

Did you remove the 6mm screw in between the two connections at the fire wall to pull the pipes out of the core?
No I didn’t
Any idea what the white lever does? Accidentally popped it out and won't stay in place.
I broke it! I dont know what its called but basically it controls whether the fan blows hot or cold air. Now i have to manually turn that lever to turn on my heat and it resets every time you turn off the car. Gonna go get it checked out this week.
It controls the blend door for the heat. It opens the door more to let more heat into the car or closes when the AC is on cold or you don't want heat
What was the point of removing the lines on the firewall on the engine side? Did you replace them?

@@biz4twobiz463 is there a nut that holds that bracket to the firewall? I can't move my hoses enough to get them off the heater core.
@@robertbrown7466 ... YES, the nut/bolt is on the engine side of the firewall. Loosen or remove so the metal hoses can be pushed in/out. Just be cautious that you do not rip the rubber grommet at the firewall that the connections are made. Hope this helps.
Could you tell
me what the yellow lever is called i broke it off
Blend door lever or arm I think
I'm having problems getting the top pipe to reconnect back to the core
Did you figure it out?
The upper hose does not want to go in! Help
On the inside?
