Engine coolant light came on today, just wondered where you guys got yours from, as I havent got the slightest!

Cheers

i got mine from BMW £13 for a litre bottle - i would personally stick with BMW as its a no no to mix different types of coolant

if you know coolant has never been changed most likely it will be bmw coolant - turquoise/blue colour

Lovely, cheers mate, how much do you reckon Ill need?

[mistryn]

try a litre bottle (hopefully you wont need more than that) but remember the litre is concetrate i would do a 50:50 mix - water : coolant

Monitor the level to see if level drops again if it does investigate where/why

i would nto advise driving around with low coolant light - top it up with bit of water if you need to use the car to get to the dealer

I thought that was just for lead -acid batteries ?

Ive always filled my cars with tap water + antifreeze - maybe I was wrong.

my car gets whatever bottled water i have left over lol

Definitely de-ionised. Even Sainsbury's sells it!

[Josh1a1h]

the engine internals without de ionised water are susceptible to creating rust within the block...

You don't 'have' to use de ionised water , I have known many people just stick tap water in and I have done on a couple of previous cars but deionised water is better as tap water has elements in I that can react and cause issues such as has been stated above
