Coolant capacity of M50 engine

[ktteoh]

if i were to drain out the whole engine, how many litres of distilled water do i need to fill it back up (assuming i don't use coolant)?

Do you really need distilled water? Is tap water not good enough?

Simple test: If your kettle is full of nasty chalky deposits thats what the inside of your rad and block will look like if you use it:(
