Ok i know its a bit late in the day to be asking this as i'm planning on doing this, this afternoon but ...
I'm gonna change my thermostat out for a new one, from what i hear its easy enough but i understand its probably best to do a coolant change aswell.
I was just wondering how much coolant i'll be looking at using? At the moment i have 5ltrs. its genuine GM but doesn't say that i can mix it or not either.
Will 5ltrs be enough or should i quickly nip out to get another 5?
i just want to be sure before i drain it and then find i dont have enough and have to wait for someone else to get me another load of the stuff.
Thanks in advance
