Anyone please confirm the correct cooling capacity.
Haynes Manuel says 8.2 Litres
Other info (searches) says 6.2 Litres
Wanting to do a 50/50 mix so do not know if 3 or 4 litres of antifreeze will surfice.
Last done 3 years ago cannot remember old age creeping in.
Mates doing Timing belt and pump this weekend.
Cheers.

Technically, you need more than 3 litres either way! (as either is over 6 litres of 50/50)
It's better to have too much than not enough - you can keep a spare litre of ready mixed 50/50 in the boot for any crisis moments - worth it for the little extra.
I know that's not a technically accurate answer to the question, but hopefully you get where I'm coming from.

Technically not, I pefer to aim for a 30:70 mix as too much anti freeze is way worse than too little, its for starters heavy than water and also lowrrs the running temperature of the vehicle, but the boiling point actual ly reduces after a certain mixture level.
Go for three litres max and you'll be fine

Cheers guys 3 Litres it is.
Thanks for the extra bit of info, explanation, Addaz.

Seeing as you've appeared to say I'm "technically" incorrect, can I ask what technical factors you're basing the information on?

Sorry some of the information I stated was incorrect, I was having a s**t but anyways a 30:70 mix is better.
Water is a better heat transfer agent, and due to the viscosity of anti freeze heat cant be absorbed or transferred into the radiator. Yes anti freeze has a greater boiling point of 387*C but as stated it will more than likely cause you car to over heat.
Water is also lighter than anti freeze due once again the viscosity. Hey its not much but ever little counts. The main reason we run anti freeze is not to stop it from freezing the engines, but for the anti corrosion/limescale agents. As a country we have very hard water, and specifically for us (cant remember the exact name but it comes under its refereed to as OATS) we run an inhibitor which creates a protective coat all across the pipes to stop scaling/rust forming

Be that as it may, any water use should be deionised water - you'd have to be a little bit reckless to use tap water in the coolant due to the horrific crap it can contain (minerals, limescale as mentioned).
Although a 30:70 mix is hardly going to spoil anyone's day, I would always recommend a 50:50 mix as it massively reduces the risk of electrolysis and/or cavitation from an overly water based coolant mix.
For the sake of probably less than £5, I would mix 50:50 with 4 litres and have a little left over for bleeding/topping up. 30% is, for me, right on the borderline of the minimum dilution, so can't see the sense in not just doing a half and half, least of all because it's so easy to measure.

You should use purified water yes, but since no one does hence why addatives are present.
Dont forget the quality of the coolant has by far greater affect than dilution, ie peugeot standard at 30:70 would be by far brtter thr triple qx normally found at ecp.
Im personally also going on the perspective you never fully drain your coolant. Ever. That is without engine rebuilds, but that goes without saying
Anyway thats were I stand. Bored now of explaining

Thanks guys, never envisiged it being a technical subject.
I will take 4 Litres to my mechanic mate and let him get on with it.
When the jobs done i will ask him what mix he put in.
He's an excellent mechanic 40 years experience under his belt, so i assume no doubt will have his thoughts.
Cheers guys

Unless you drain the engine block as well other wise you don't need that much coolant....

I get the gist of it all now, i presume the Haynes 8.2 Litres is with draining completely. ie the engine block.
Haynes should point that out.
So 6.2 Litres is the norm.
As Addaz points out you do not ever drain the block. and am also assuming the heater matrix will also have some remaining.
Just came accross this same senario

Thanks.
