drain water/ antifreeze

I want to drain a couple of litres of water out to put antifreeze in, i know i can undo bottom hose, but been not so agile at the moment, can i disconnect the hose on the top up bottle, and lower that, start engine, it should drain out.

you could just wait for the head gasket to blow, that'll be a quick way to drain it and should be along fairly quickly with it being a gaylander

or buy a V8 and use it as an ornament

At least I can drain the coolant out of that by undoing the rad clips and lifting it out did it in under 10 mins the other week

Undo top hose, pop out, tilt back, undo bottom hose and away it goes

Easy i take the bottom hose off, unscrew the expansion tank cap blow very hard into the tank and the coolant flys out

Bet you've had lots of practice blowing things

Draining the coolant from a K series is a ballache but there's no other way to do it that I know of

not very well at the moment or would take bottom hose off,will it drain how i am thinking of doing it.

Take pipe off point at ground, run engine til it warms up and stat opens and it should pump it out

thank you i thought that looks a better way

dead easy, only took a pair of plyers, took clip off bottom of fill up tank hose, lowered it and water came out,easiest antifreeze change i have ever done, no crawling underneath and getting soaked and dirty.

Easier than that to do, just undo the plug to empty the sytem of air on the heater hose, and it will start to flow out, at the same time start to fill gently with you mixture of anti freeze when it goes a darker colour quickly do the plug up. simples then check if it is correct with a tester

would not the antifreeze go straight to the bleed plug

Well I wouldn't be happy unless I had got all the old coolant out!

I used a pair of pliers to take off the spring clip on the lowest hose I could reach easily, without dropping the under-tray/guard - opened both bleed valves and took the cap off the expansion tank.

I refilled it, bled it and then let all the water out again - twice - between times running the hose into the expansion tank until clean water ran out the disconnected hose..

Only after I was satisfied that there was no trace of the old coolant, did I pour in the required 4 litres of OAT fluid and topped up with water.

There are 7.3 litres in the system so that gives me just over 50% mix which gives protection down to -40 degrees C.

Come on the winter - it was -5 here last night.

Hi did you use the correct anti freeze ?
The old blue stuff won't mix with the modern oats antifreeze.
It goes like jelly and blocks up then you need to flush the complete system.

I think that was true when OAT first appeared on the market years ago.

So if you have a container of either type, left over from when Queen Victoria was a little boy, you need to beware mixing them.

However the latest stuff both blue/green and the red/orange/yellow variety, can all mix together if need be - but ....... you lose the long life benefit of the OAT and it needs to be changed every 2 years just like the old technology kind needs to be.
