Hello everyone,

 

I have been made aware of the possibility that the header tank may contain a silica bag which is intended to prolong the life of the coolant, but can sometimes split and clog up the heater matrix, resulting in a massively expensive repair.

 

How will I know if my specific tank has the silica bag in it or not please?

 

I can't see any marking relating to "mit silica" or anything like that, but the markings are partially obscured to the right facing the inside of the engine bay.

 

Any advice would be very welcome?

 

Thank you

The mk2 Superb doesn't have a silica bag in the coolant.

 

That came on the newer models, from I think the mk3 Octavia.

cheers mate, is that 100% definite - some people on a FB group had said some of the Mk2 models had them as well, so I'm a bit confused.

The marking with Mit Silika is on the upper 1/2 and would be visible so if it’s not there you’re ok. As mentioned above it’s only mk3 onwards it seems. I had concerns too!

Cheers Nigel, that's reassuring
