Has anyone heard of the potential issue with the mk7 or mk7.5 coolant tank, see screenshot below from a friend of a friend.
Basically he states that a coolant tank made by Mit Silikat contain a bag that has silicone beads, the bag has been known to rupture after 3-4 years, causing blockages in the coolant lines. This in turn has serious repair costs.
Is this bullshit or a genuine concern? See below.....He just mentions Golf and not the R but I assume it’ll be the same?
Any of my friends with a Mk7-7.5 Golf?
If you have? Have a look at the header tank and if it has MIT Silikat written on the side of the tank, then there is a bag of silicon beads in the tank? Get it out if you can? The bag bursts after 3-4 years and floods the coolant system with silicon beads leading to blocking the heater matrix?? Costly repair as dash etc. Needs to come out? You can fish the bag out with a pair of pointed nose pliers?
Better prevention than cure?💪😜
Oh and be careful not to burst the bag while taking it out🙈
If all else fails a brand new header tank without said bag of beads is only twenty odd quid😜
