Hey all,

Like a fool, I mixed pink coolant in with the blue coolant which was already in there. So I now need to drain this out ASAP, as it turned grey within an instant!

So my question is, what coolant do I need? Something simple from Halfords will do the job I imagine?
Also how the hell do you change the coolant? There doesn't seem to be any pressure release valves or anything, so a quick run down would be helpful

Thanks in advance.

It wont do any harm just drain it then replace with either pink or blue,
pink is longlife blue is just standard also if its classic shape you don't bleed em up you need to pour liquid in very very slowly so you don't get air bubbles in the system.
on my classic i had a drain plug right at the bottom of the rad.

 

Thanks. The car is a Blobeye STi. Are you saying the blue/pink mix won't cause any harm? Pretty sure I've read it could caused problems? Either way I'll be changing it to be on the safe side

 

Dead easy to drain it, but mixing the blue and pink isn't the end of the world.
If you want to carry on and drain, then just safely jack up the front, from the passenger side. This gains you access to the bottom radiator hose, once you've loosened the jubilee clip, its a fight to get the bottom hose off.
Have a bucket below it and once the hose is off, aim for the bucket. Now dry off as your be wet lol...
It you want, you can run some new, watered down just as a lil clean through, but certainly not necessary...
Re-attach the lower radiator hose and tighten Tue jubilee clip.
Ideally use a funnel, slowly refill with new coolant.
When full, start the engine and let it run for a touch, then refill when its cycled round.
Hope this helps...

 

I would change it.

Facing the car from the front, there ought to be a drain plug on the lower left of the rear of the rad, driver's side, that is. Have something ready to catch coolant, it holds 5 litres.
Once it stops, remove the lower hose from the rad and allow more to drain out.

Refilling is done S L O W L Y

I used Carplan pink, it was recommended me by a local factor as being OK for alloy engines.

Ok thanks for the tips so far

 

Some pink coolants have amino acids in them (these will harden alot of rubber o-rings)
Where you based mate?? If youre in London i can give you some free BMW antifreeze. which i have run in my 2002 wrx for almost two years now without issue.
