Fix Your plugged Heater Core for $20

[@sykadyki]

Had the exact same problem and your fix worked, now my wife has heating again 😊😊

That’s great to hear!

I was able to rig one of those cheap Harbor Freight hand pumps to the hoses so I could agitate the CLR back and forth thru the core occasionally while it sat. Switch the ports and agitate from both directions. Im letting it sit overnight.Fit tight on my hoses but yours look larger.Thanks for the video !

For what it’s worth, Honda has a tsb for cleaning out a clogged heater core, and they recommend using clr for flushing.

CLR ( Calcium , Lime , Rust ) Remover works well heated up and recirculated through the heater core . A 5 gallon pail and an electric pump is needed !

Could you explain the reason for clamping that one hose with the vice grip? My son’s Tiguan has this same issue, will be doing this when he’s home from college for Christmas. Thanks for the great video!

Thanks I have the same problem.

I noticed my heater barely getting warm AFTER I added Bar's Stop Leak to the overflow reservoir a few months back because I have a slow water pump leak. (I didn't have $2500 for a water pump replacement for my 2013 VW CC!) The water pump seems to be a very slow leak now, but not sure if Bar's clogged the heater core...🤬 I wonder if radiator flush stuff will unclog the heater core...? 🤔

The bars leak will plug the heater core. You can try fluh it out, but you may have to replace the heater core now.

[@jerrymc777]

@@BaggerJay I was able to drain the radiator and back flush the heater core. Now my heater is back and the water pump does NOT leak! 😁

[@allenbarta8299]

All great information I don’t want to spend money at the dealer very expensive.

I am having some trouble locating these tubes. Anyone know how to get to this first step from opening the hood of the car? 😬🤷🏻‍♀️

[@squatchy69]

Isn't the crap that came out of the hose from using CLR in a prior flush? Different owner?

Hello. I have a question for you...what is the size of PVC conectors? (1/2 or 3/4 inch)???

[@freddye7442]
