I ended up doing this, because I had flushed my car's coolant system four times. Still was getting a cold heater. I used Draino instead of CLR. Then used dish soap. Flushed it out both ways several times out with warm to hot water. Now my heater works like a charm. Thanks for your information!!
Lil bro that was the best step by step procedure that I seen yet and I researched for a week.. I appreciate an all out effort!! You got people wanna post stuff and leave Lil things out when an inexperienced person will get lost..People need details and results(that’s the only problem)you said you’d let us know either way but didn’t..Man answer them peoples questions (they are ya fans and followers)me too!!In this regard!!lol..Don’t worry about haters do ya thing!!
Hey man, nice video, I would like to see a conclusion on your videos. Often you do a project and upload it. Would be nice to see how it all turned out in the test drive. Not hating, thumbs up man
Can I flush the system without flushing the heater core? Because my coolant is brown but not that brown I put the correct coolant in but I think the people that it before me used the wrong kind. Coolant isn’t low but the warning started flashing maybe a month after I topped it off.
Wahhh So what was the end result did the heat work, Here in Canada it's freeeezing cold and my 03 Audi A4/ 1.8T heat hasn't worked in years.. we be running tempt portable plugin heat for past two years, it's time to move to south America missing hot sunny days..
Audis are famous for the I too miss the south use to have a house in Florida why did we settle in Ontario oh I can't wait for winter and scraping the inside of the windsheild lol😂🤣😂
On my 06 A4 1.8t the heater hoses are on top of each other the supply side is the lower hose and the return is the upper. But, you can tell which is which because the supply comes from the coolant flange at the rear of the engine.
@@BUILTOFFICIAL Hey , just wondering about the bubbling sounds on heater core. . I hear those sounds too. Could be the sign of air presence in cooling system .Just wondering if trying to bleed the heater core would help me . Thanks
I don't know if Dexcool is compatible with G12 or G13 (the coolant spec for your car) but I would imagine neither GM or VW/Audi will declare that. Use the right spec.
I flushed the cooling system in my Miata project 12 times and it was never perfectly clear! I need to flush again with a dedicated cooling system flush and see how that works.
I do not recommend using CLR. Always buy a coolant system flush. CLR has detergent in it which will screw up O-rings etc. Never use any coolant that is not specifically recommended by the OEM.
The main reason the A4B5 heater won't work. It's the foam on the heater box flaps has disintegrated. To check, remove the centre vent in the dash & look for bits of grey foam. If you find it, you need to remove the heater box & glue new foam over the flaps. A cheap, but time consuming job to remove & replace the box. Be patient. It can be done. Remove the actuator motors & cut thru the carpet under the box for better access. Remember the movement & positions to get the box out do you can get it back in.
Or you can remove the whole dashboard. If not, you will need to cut thru the centre upper vent duct & reflux/seal it back on afterwards. I looked some nichrome wire around the back of it, as high as possible & connected wires to it & a car battery to 'hot wire cut' thru it. Depending, removing the dash might be better.
you are so wrong. first you need to take out the a/c condenser in the firewall.of course you have to have a machine to get the refrigerant in the a/c system then you have to take the glovebox,center console,then you will see it in the PaSSENGER SIDE.then you have to get the whole A/C and heater core in one assembly unit. takes about a day to it. EASY LOL
Nah, it's a pain, remove whole dashboard, A4B5, or remove the clips holding it to the aircon box & cut thru the upper centre vent & reseal it afterwards, there's no need to keep the springs holding the centre vent.
you did not show how to get that front bumper off, one second you were messing with those two little black plastic grills , then next scene ,they are magically off.
GM's DexCool did the same clumping BS. What a waste of time after doing a half assed flush. Use some CLR in the core for a few minutes before you flush with water. You realize by taking shortcuts and using wrong products that all you are doing is fucking up others. What did you do with all the toxic waste from the job. Where did you dispose of the coolant?
