Attention VW, SEAT, SKODA & AUDI (and maybe others) owners. In this video I will be showing you how to remove the SILICA bag from your cars expansion bottle. It becomes a problem in time when the bag inevitably splits, contaminates the cooling system and causes the heater matrix to block up. Unfortunately this has been the case for many owners already! These costly repairs can be easily avoided and in this video I will show you how to prevent it happening to you. After all, prevention is better than cure. Do some research about the subject and decide for yourself whether it’s worth the risk.

Thanks for a good video explaining. I myself am a technician for VW. Strongly advise for anyone to try and get these replaced. I tend to remove them when I see one that’s not a double skinned type and inform the customer that it has been removed. If it is a double skinned layer I advise the customer to have the coolant bottle replaced. Prevention definitely better than the cure you got that right! Flushing them and replacing the heater matrix is a pain and can save you so much money by getting this done. They tend to be mainly on the diesels but you can find some of the MK7 GTI’s as well as the R's have them too. Hope this helps anyone. 👍🏾

Hi, just checked my 2019 vw golf 1.5 tsi and there is no Mit Silikat written on the expansion bottle only G13. The bottle is a double skinned one. I lit the bottle up with a bright torch and can't see a bag.

@neolerades2987 9 месяцев назад

The silica gel bag is only there for the G13 liquid to improve some of its negative properties. The G13 was (I think in 2018) replaced by the more modern G12 EVO - and it is generally recommended to get rid of the old G13 as quickly as possible as it causes degradation of some components, then flush the system with clean water and add G12 EVO fluid. The tanks for the G12 EVO no longer contain a bag, I have a Škoda TSI 2019 and I already have a G12 EVO without a bag.

@scott4207 8 месяцев назад

As a technician of VW for over 14 years - the reason these bags split is because casting sand (from when the engine block is formed and casted) was never fully cleaned out upon assembly, so you had this sand travelling around the cooling system, effectively shot blasting that bag to pieces and eventually splitting it. The proof? Take your blocked heat exchanger (as this is the first component to usually fail, passenger side only gets warm air coming through and drivers side is cold), air blow that blocked heat exchanger out and you will get sand, along with silicon coming out.

@StreakyP 9 месяцев назад

quick tip on removing hoses, push them off with a screwdriver on the end rather than pulling them off.... pushing makes them balloon & expand to come off easily... pulling them makes them contract & hold on tighter.

@aluminumfalcon552 9 месяцев назад

Most of the time the difficulty comes because the hose has adhered to the nipple, if you give it a twist to break that adhesion, it will slide off fairly easily. There are hose pliers that do what you described much more safely and effectively, you stick them right at the end of the hose and squeeze and it forces the two forks away from each other. Another handy tool are the small o-ring spoons that are curved, you can reach them in between the hose and nipple and break the seal without over stretching or poking a hole in the hose.

@desertstar223 8 месяцев назад

You're quite right. Use a screwdriver. It will aerate the hose with a nice hole. Get the clip off by pinching two 'prongs' together with a big pair of pliers or a vice grip. Or just buy the tool that is designed to remove the clip.

@josepeixoto3384 8 месяцев назад

you are absolutely right, most people don't know that; however, it is not always easy to pry and push it out,so what we do is the usual *twist and pull*

@1marcelfilms 8 месяцев назад

It can help if you push the hose on further first too. And a little silicone grease when reassembling. And a layer of electrical tape where the clamp sits to stop the clamp from digging into the rubber

I have learned about it today from you!! What Volkswagen did is they think it’s a good idea to put a stupid silica bag inside the expansion tank is not idea BIG TIME just to make a longer lifespan of the cooling system!!!🙄🙄 Another thing you can do if the bag is not inside the tank, instead of just pull the bag out and risk of splitting the bag and clog the system up, remove most of the coolant out, remove the hoses and take the tank out, and then remove the bag! Put it back together, job done! That way you won’t risk of split it by pull out while it still connected! Hope this helps!😊

Wish I had seen this 2 years ago. I had a Seat Leon, just a few years old at the time, silica bag split and the repair bill was almost £1000. If you have a VW group car with ‘MitSilikat’ on the expansion bottle change it as soon as possible. Top video thank you.

@paulestherby9351 9 месяцев назад

Absolutely right with this video. I have a vw golf tdi and this problem happened to mine. Had to have a new heater matrix. You will know when the matrix is blocked as the heater will just blow cold.

I know someone who had this issue and it was a £700 repair on a Golf TD. 'Somone' deemed this bag necessary but I wonder how long it functions for until saturated with free water? I think I'd rather replace the coolant a bit early than leave the bag in there indefinitely. I've been meaning to take a look in mine to see if the bag is there. Thanks for showing how easy this is to sort. Quick update: couldn't find the bag in my expansion tank, though the writing says 'mit'. To double check I removed the tank as described here and shone very bright light through as this should show in shadow and thankfully no bag. Agree with the comments on here about pushing rather than pulling hoses and I also suggest using a pick tool to ease the hose away if it's tight on the fitting.

@phils3 9 месяцев назад

This happened to my Leon Tdi. First symptom was unexplained coolant loss. A garage I tried couldn't replicate the problem on the ramps, because it was happening during DPF regen, when the coolant would get too hot because it couldn't circulate properly due to a blocked heater matrix, and would blow out of the pressure release on the expansion tank. Took ages to find out about this issue on the net. When I thought I had a leak, made the mistake of putting K Seal in (DO NOT do this) which finally fully blocked the matrix. Much of the passenger side of the dash has to come out to change the matrix, which was a bit of a pain, and it all needed a really good flush to get the silicon and K Seal out. If it hasn't happened on your TDI, get rid of the bag. If it has, good luck. Thanks for the video, good explanation, I hope people see it.

@Rayfaedundee 9 месяцев назад

The Silica bag is normally located at the small area to the top of the bottle in a small chamber. I remove loads of these when I’m servicing VW, Seat, Audi, Skoda models. It is a silly idea to put a plastic teabag of silica gel beads into a hot coolant system, that if the coolant does get too hot can make the plastic bag burst open and all the beads eventually block up the heater matrix, then you end up with no heat inside the vehicle because the coolant can’t circulate around the heater. Big expensive job just for a small bag of un-necessary silica beads.

@Felix2417425 9 месяцев назад

You end up with no heating in the vehicle, but does the cooling of engine works normal or it also may clog up the radiator and cause engine overheat? That's far bigger concern than having no heating.

@Rayfaedundee 9 месяцев назад

@@Felix2417425your heater matrix has very fine coolant core and the silica beads clog up this fine core and that’s why you end up with no heating, the main radiator has bigger core for the water system so it has less chance of being clogged by the silica beads.

@marttijee 9 месяцев назад

From what I have read the reason for the silica bag is to stop the coolant causing corrosion on the aluminium cylinder head. Nothing to do with prolonging the life of the coolant.

@Benzknees 9 месяцев назад

It seems to be both, as there are silicates in the coolant, to protect the aluminium components, but these get used up if the engine is subject to heat (so degrades the coolant). Then the silicate is taken from the permeable bag to compensate.

The filling of this system needs a vacuum filler and premixed antifreeze. If you ring VW you will be told only they can do this and will give you a form to remortgage your house...... How is it that Honda and Toyota have antifreeze that is a long life anti corrosion solution that is good for 10 years , and when change is due is piss easy to drain and refill.... can't beat German engineering ??😊

If removing silica bag etc change coolant to latest coolant as recommended by VW : G12 Evo is now required in all VW Group vehicles This is the most up to date, latest version of coolant from VW Group. G12 EVO is the latest correct coolant and replaces G12, G12+ & G13, it may have been made after your car was built (this will be the reason it may not appear in your handbook/manual, or on the coolant cap itself) • Direct use: It is ready to use, it is not necessary to mix or dilute it. • Original G12EVO Ready Mix coolant is specially designed for the engines of the VW Group’s brands. • G12EVO replaces it's predecessor G13 and G12 ++. • G12EVO can be mixed with its predecessor products like the G12 Plus Plus, G12 +, G11 • Can also be used in vehicles where G12/G13 is required, such as Porsche.

This isn't the only think to change of a VW before it is too late.. Vw use a waterpump that has a sheath that goes over the waterpump fins, which is controlled electronically. The sheath can jam when over the pump fins causing the reduction, or completely stop the flow of coolant around the system, causing the engine to over heat. Quite a lot of waterpump kits now come without the electronically controlled sheath to prevent this, I would recommend doing so. I know it was an issue on the 2.0tdi engines but unsure about the other engines. Someone may know more about it than me, who could say which.

Coolant Expansion Tank with Silicate Repository The coolant expansion tank contains a silicate repository. Silicate is used to protect the aluminum components in the coolant system from corrosion. There are silicates in the G13 coolant, but they are used up over time if the engine is subject to high thermal loads. To compensate for the silicate consumption, silicate is taken from the repository and added to the coolant. The silicate repository provides additional protection against corrosion for the aluminum components in the coolant system over the entire lifespan of the engine.

"The silicate repository provides additional protection against corrosion for the aluminum components in the coolant system over the entire lifespan of the engine." "Lifetime filling" Just like the transmission and everything else... After you reach 100.000km just throw the car away and buy a new one.

@TurnersWorkshop97 4 месяца назад

Very strange, surely when the water pumps are changed they replace the coolant? Was it done at the main dealer?

@chris-eccohealthcare 4 месяца назад

Yea been in the main dealer. Story starts back in September 23 when the engine light came on. Took in to VW Ayr where i stay. They changed one water pump and then had the van 4 week and same again. This time they replaced the dpf and another water pump. And so the story goes on. I thought it had the silicone bag but they told me my van doesn’t have one. The van is now back with them and they have sent the coolant away to be tested.

@zapa1pnt 8 месяцев назад

Good information. However, it is inadvisable to try to remove the silica bag, from the bottle, while it is in the vehicle. You have no way of knowing what condition it is in. If you break it, you now have silica loose in the bottle and you can not start that engine, until the bottle is replaced or you will have silica in your engine. This means that vehicle is stranded until you find another way to the dealer, to get a new bottle. It is best, if you have such a bottle, to simply get a new one and replace it Before touching it and Before you have a serious issue.

Bought a VW group vehicle a couple years back and found it had one of these teabags. Decided it had to go and carefully was able to fish it out the top using needle nose pliers and a thin pair of the wife's kitchen tongs. I was shitting myself the whole time I was teasing it out though in case it split, luckily it didn't.

I change out the coolant in my ‘13 FoST every three years. It’s not hard and the coolant is cheap. I don’t see the point in putting a bag of silica in the system when it’s likely going to be a source of failure. It’s just a bit of unnecessary engineering cooked up in a development team meeting. Sometimes the bean counters are right.
