G13 antifreeze for Alde

It might be wise first to check that out with Alde UK.

It's what Alde specify G13, the cheapest Alde labelled bottle is £8.99/ltr

Extract from Alde manual

Alde Premium G13 Antifreeze is pre-mixed with deionised water and ready to use in the Alde system, suitable for even the Scandinavian winter. The silicated OAT corrosion inhibitor is compatible with the silicate-containing antifreezes used as standard by most UK vendors, and provides 5-year protection.

G13 as a specification was launched by the Volkswagen Automotive Group in 2013, and is now used in Audi, Bentley, Bugatti, Lamborghini, MAN, Porsche, Scania, SEAT, Škoda and VW vehicles. So it's commonly available from anywhere you'd expect to buy antifreeze for your car engine radiator.

G13 officially supersedes G12++ products, offering the same benefits from a more environmentally friendly manufacturing process.

Here's Euro car parts spec. 

Ready Mix Triple QX MEG & Glycerine based antifreeze, incorporating the latest in Organic Acid Technology (OAT). It is environmentally sustainable and offers winter protection upto -36 C dilution.
Purple (G13) Ready Mixed Antifreeze/Coolant - 5ltr
Suitable for all engine types conforming to British Standards BS6580 (2010) and VW G-13/TL 774J & NF R 15601 type 3
It can be left in the system as a coolant and rust inhibitor for up to a maximum of 5 years in accordance with vehicle manufacturers requirements.

How did you find the process DIY. We have recently brought a caravan with the Alde heating system and I was thi king of doing the change myself. I have found a few clips on u tube and it seems fairly straightforward. 

Ready mixed to what concentration? 

50:50 concentration ok to -36C with 5yr lifetime

Not too difficult, tilt van towards drain point, remove bung  drain old fluid, flush replace bung,  turn  pump speed circulate until air is out. You need to bleed air from highest bleed point.

There's several videos on YouTube with more details.

viatorem, you may well find that you have to bleed the system a couple of times during use to ensure that all the air is expelled.

Thanks will check before next trip.

Haven’t been on this forum for a while so only just seen this posting. I checked directly with Alde about a year ago and they were very insistent that they do NOT recommend the EuroCarParts ‘G13’ antifreeze in their systems. It Is always possible that they’ve changed their stance over the past 12 months but I wouldn’t use it without checking first.
