you own a wasserboxer (waterboxer i.e.. a water-cooled flat four, 1.9l
- 2.1l) then you need quality antifreeze, you need phosphorous free antifreeze,
on these engines the cylinder head studs corrode, this is common knowledge
but its caused by not changing the coolant at the correct intervals. Antifreeze
contains corrosion inhibitors, which as the name suggests inhibits corrosion
of the cooling system, the radiator, the heater matrix, the alluminium
alloy engine etc., also your cylinder head studs.
If the interval is not adhered to then the cylinder head studs will corrode, and they won't grow back! and get to a point where they snap leaving you with an expensive repair bill for what will probably end up as a new engine as the broken parts are nigh on impossible to remove.
This can be avoided by regular coolant changes, whatever the engine the coolant should be changed every 2 years, although it is more important for WBX owners.
VW's own antifreeze is the one to go for, there used to be 2 types of VW antifreeze, G11 which was blue and G12 which was pink, the pink stuff is what you want but I now hear they have both been discontinued and replaced with G12+ which is compatible with both G11 and G12 and is purple in colour. There are other manufacturers of antifreeze which are slightly cheaper, Comma being a reputable brand and offering a pink phosphorous type.
bare in mind that if you have an empty system the entire cooling system
takes 16 litres of coolant, if you want a 50% mix then that's 8 litres
of antifreeze you need, and a little fact here that neat antifreeze
actually freezes at -6°c! its not until its mixed with water that
it lowers the freezing point, so be careful, too much antifreeze could
end up being the death of you engine. Another fact worth considering
is that you want your antifreeze protection at about -35°c, that
sounds a lot and even most mechanics will say its never going to get
down to that level, but the correct concentration is essential not just
for ice protection but for corrosion protection also.
