Another tip: Before turning off the engine and starting the job, be sure to turn the heater temperature position to maximum so that you also flush the heater core.
The only way to properly flush heater core is take heater core pipes off at the bulkhead and use a steady stream of water through a garden hose through the inlet and outlet, then blow all the water out from heater core and pipes leading in and out of it. There would still be old coolant left in the engine water jacket and associated coolant pipes. In my opinion, this video shows a partial coolant drain.
I just replaced the coolant & the ATF together 2 days ago. Both were fairly easy to do. BTW, I did not squeeze the hose to burp the system but just start the engine and the coolant would fill into different places in the system and just top off the coolant to the max line and that's it.
Great video! Think it's important to explain why to bleed the system to anyone planning to change coolant DIY. If you don't then you might get airlocks and the coolant won't flow properly, overheating and damaging the engine which isn't fun!
@@kyreesanders9422 I believe this to be true. I have a new heater core. My heart is low or weak. I shop vac out coolant and topped up a new batch. Now I see there is air lock so best thing to do is drain and squeeze the hose. I suspect a leak but the coolant wasn't seen dripping on anything. Try just squeezing the hose with the cap off and see what happens.
I can provide my debriefing: Dissasembly was pretty much as shown, but the clamp for the coolant hose, some sadist at VW had put it on with the clamp-flaps facing away from me! I could not easily squeeze the clamp. I nonetheless attempted to position the tool behind the pipe and on the 20th attempt it worked! Now came removing the hose. One tip I can provide is to actually loosen the mouth of the pipe all the way around with something thin but not pointy just to loosen the years of it sticking to the plastic. It pulls off much easier this way. And when it came time to top up the coolant, I never got the fan spinning. I let the engine run for a long time, letting it air bubbles, but it mustve been a cool evening because it never came close to 90C (200F). I went for a drive and stopped several times to top up the coolant, and will continue doing so until it stabilizes, have added about 2.25-ish liters til now, which is about how much came out. Fun job! Thanks for filming it so well!
I know this was awhile ago but do you happen to remember what you used to loosen the mouth of the pipe? Where I live we get a lot of rust on our cars I’m willing to bet mine will be glued on 😅 Put the wrong coolant in my Golf
Good video I just wish you made clearer the location of the hose and if you were coming from the top or bottom. I’m still disoriented but I’ll figure it out.
What about the old coolant left in the heater and heater core pipes aswell as the engine water jacket. This is a partial drain as some old coolant is still left inside the system.
how long did you squeeze the hose? i did it for like 8 minutes and there was still some airbubbels, then it started raining .. will continue tomorrow..
It depends on the coolant you buy. Some of them, like in this video, are already mixed to the proper ratio. Others are concentrated and you have to dilute them with water.
I did this on a 1.9tdi vw bora and it’s still overheating is there any tips you can give me to fix this? I ran the car and put my heat on max and it didn’t work, I flushed 3 times and continued to overheat and have no heat inside
I suggest buying the proper locking hose clamp tool which costs less than $20 and you can use it on all of your hose clamps in the engine. It is worth its weight it gold!
@@screwsnutsandbolts You will love it! It can lock the clamp open so you can move it out of the way with the tool still attached, saving your hands and knuckles. I have one in my garage and one in my car's tool kit.
It just drains the fluid in the radiator and most of the fluid in the engine block. If you want to completely flush the system, use the following steps: 1 Remove the lower radiator hose and catch the draining coolant in a bucket. 2 Remove the top radiator hose and flush the system out with a normal hose. 3 Continue until the water runs clear out of the bottom of the engine.
Does the car's front need to be jacked up for the whole process? Or just until your remove the undertray and disconnect the radiator hose? Would the flow be easier if the car wasn't jacked up?
No it doesn't necessarily need to be jacked up but it makes it easier to access with the car raised. You could probably drop it down as you're draining the fluid but I don't think a few degrees would make too much difference.
I v just changed a pipe in my coolant system like 1200 km ago and m loosing cooling slowly, i am at level max but it was above that level.. and now just below the level max, should i add more colant like you did ?
The connector( a rubber one) in my SEAT IBIZA was broken just before about two hours today because I applied more pressure while removing the hose. That is how I came to these videos. What should I do please?
It will still be there but it is OK if you change your coolant at regular 30K mile intervals. Just be sure to use exactly the same spec as what is in there. Otherwise, you can seriously damage the cooling system and your engine. If you want a complete flush, I suggest you have a professional mechanic do it with the proper equipment which is what I did when I bought my used Rabbit. I wanted to start out with 100% new. After that, 30K interval changes are good enough. I've been using this method for many decades in all of my vehicles with no problem, regardless of country of origin Just be sure to use the CORRECT SPEC COOLANT!!!!!! DO NOT MIX DIFFERENT TYPES TOGETHER!!!!

if i bring to mechanic and do the job, how do I know that the mechanic will flush my heater core or not ?
@@limpei94 you will tell him to do that.
will the heater core water circuit of a digital AC remain open after turning the car off?
The only way to properly flush heater core is take heater core pipes off at the bulkhead and use a steady stream of water through a garden hose through the inlet and outlet, then blow all the water out from heater core and pipes leading in and out of it.

It's the taking of pipes and running water through them thought that scares me on this particular job duno why I think I'd do something wrong
This was a great video. I like the way you inserted text to read about key points. I wish all videos were as comprehensive. Awesome job!!!
Thank you !
I agree. Its like job training.

Would that also be the reason why heat isn’t working ?
You won't get airlock on mk5 vws. It's a self regulating system. How he did it is correct.
You just turn on the engine with radiator cap off

Will this same method work for a 2016 passat. My main issue I'm afraid of is locating the drain plug.
I haven't worked on that model so I can't be sure, sorry
how long did you squeeze the hose? i did it for like 8 minutes and there was still some airbubbels, then it started raining .. will continue tomorrow..
I only needed to do it for about 3 or 4 minutes.
briliant! Seems like an appropriate DIY job for me!
Thank you !
Must add distilled water or just coolent 💯 percent?..
It depends on the coolant you buy. Some of them, like in this video, are already mixed to the proper ratio. Others are concentrated and you have to dilute them with water.
How many liters of fluid went into the tank?
Cant you just start the engine without the lid to get rid of the air bubbles?
Excellent video
Thank you !
Can green antifreeze be poured instead of this pink antifreeze?

No drain nut ?? Or we need to remove hose ??
Some models do have a drain but unfortunately not all.
I suggest buying the proper locking hose clamp tool which costs less than $20 and you can use it on all of your hose clamps in the engine. It is worth its weight it gold!

How much you manage to drain only from the radiator?
Hi how many litre de coolant i need to buy for my golf 5?
8
Why 8?no 5 litri?
Does draining the coolant via water pump also drain coolant in the radiator
I'm not too sure to be honest.Is the water pump lower than the bottom of the radiator drain ?. I don't have the Golf any more to check.
Does this completely flush the radiator?
It just drains the fluid in the radiator and most of the fluid in the engine block. If you want to completely flush the system, use the following steps:
1 Remove the lower radiator hose and catch the draining coolant in a bucket.
2 Remove the top radiator hose and flush the system out with a normal hose.

Does this work for seat leon 2014 1.4tsi?

how many liters did it come out approx
I think it was about 4 liters
Is there no bleed valve on these cars.
Only on some of them apparently

I havent see cooling fan to work on my car? ..its 1.6vw tdi.
Is the engine overheating ?
I v just changed a pipe in my coolant system like 1200 km ago and m loosing cooling slowly, i am at level max but it was above that level.. and now just below the level max, should i add more colant like you did ?
Keep it topped up to the Max level but if it keeps losing coolant you will need to find out where the leak is and repair it.
Is the coolants water diluted with distilled water?
If it's pure antifreeze then yes, you dilute it with distilled water. Some coolants are already diluted when you buy them in the shop.
Why not use the drain plug?
This model didn't have one :)
The connector( a rubber one) in my SEAT IBIZA was broken just before about two hours today because I applied more pressure while removing the hose. That is how I came to these videos.
What should I do please?
If the plastic connector broke off the radiator you will probably need to replace the entire radiator unit
Hi. Do you use pure coolant or mix it with water? My mechanic told me to mix it. Am driving a 2012 Sharan 7n. Thanks.
I used a pre-mixed coolant. If you have pure coolant, you will have to dilute it with water before filling it into the system
Thank you
You're welcome
Would this also work on the 2.5 engine? I am planning to get new coolant and the actual coolant tank
I'm not 100% sure but it should be a similar process
How about the coolant that is still in the Block?
It will still be there but it is OK if you change your coolant at regular 30K mile intervals. Just be sure to use exactly the same spec as what is in there. Otherwise, you can seriously damage the cooling system and your engine.

how much liters does it take to get filled?
On this 1.4L engine (Code BCA), the manual states it's 5.6 litres
@@screwsnutsandbolts thanks for the reply
You're welcome :)
What happens if you go over the max line abit??? You filled it to the top line, I’ve gone abit over that ??? Thanks
If you've only gone over by a small amount it shouldn't be a problem. If you need to, you can remove some with a syringe or turkey baster

Fan doesn’t turn on
why was the coolant dark orange in the beginning and then pink in the end?
