coolant

[Chris5044]

hi guys was wandering is it what coolant to use for the s2... is it an audi brand only?

the main question is: is the s2 coolant system self bleading ......if not where's the blead points?

pls

[rotoryboy]

Not really self bleeding. The 3 points are, exp. tank cap, top of rad and the hose that goes to your heater matrix has a bleed screw in it.

You must use G11, G12 or G12plus can be bought from GSF for tupence.

Go for G12plus as G11 and G12 cant be mixed together where as G12plus can be mixed with either.

Bleed screw on rad

thx mate but spotted that one...... any others? like where on rad and do i have to run engine?

Hi Chris,

Basically, fill the res. tank as normal and open the valves at position 2 and 3. Start the car and leave to run upto temp then turn on the heater to full/hot. Keep topping up the water to the right level(max) and wait for the air to disperse from the top of the rad. (water flow will be constant). Close this and do the same thing for the heater hose at the rear of the engine compartment. Check the heaters are hot, then bobs your uncle. People have different ways of doing it this is just one way

Please note this as my main dealer did this on the S2 with the result that the coolant was full of deposits until cleaned out.
Main dealer even denied it was an issue suggesting my radiator was rusting until I got a specialist second opinion and insisted they sort it !

If starting from scatch use G12plus

a big thx guys .... got 3litres of g12plus..... gonna drain, flush n refill thx

As has been said, its best to set the heater controls to 'hot' before doing anything else. Its then easier to drain, flush and bleed the system fully.
Also, get hold of some 'de-ionised' water if possible (Halfords etc). You can get 5 litres of it for only a few quid and use that to mix your G12+ with on the final fill.
