hi, can i buy coolant ready to pour into the radiator, or is it a mix of solutions? Sorry to be dense, im used to 1960s vintage motorcycles! Bike is VFR400 NC30.

You want a 50% solution of a glycol based antifreeze.
Most have about 2% inhibitor too.
But check.
You can get pre mixed but it's very easy to do your self.
Bottle of drinking water. (if you don't trust wot cums oot yer taps.)
1/2 Antifreeze
1/2 water
Mix together
Add to radiator neck.
Leave it for a bout an hour to make sure all the wee bubbles have came to the top and add some mixture to top off.
(Squishing the hoses helps the bubbles thing)
The level in the expansion tank should be what you are aiming for.
It has been washed out hasn't it?

Really you should use Deionized water. You can buy premixed stuff at Halfords or as Walloper says just mix your own at 50:50.

Once you've drained old coolant the Haynes suggest you use a flushing solution, then fill up the system with water and run it until the bike is at normal temperature drain again, then add you coolant.

Fill it up to the base of the filler cap, squeeze the hoses (too and from radiators) tilt the bike a bit to will help. Then run the bike with the cap off, let it warm up and give it a few tugs on the throttle (up to 5k) to help clear out any trapped air. Top up the radiator if needs be and the expansion tank to the upper limit. Replace the Radiator cap and you're good to go!

Go for a short ride and check levels when you get back

AFAIK you can buy premix , it should be good enough for most modern bikes.

Pre-mix is a con, it's cheaper to get de-ionized water and concentrate, then mix it yourself. At least it was a con last year.

I just used to use what came oot me tap and never had any problems, depends if you live in a hard water area though.

I got some Silkolene pro cool not long ago - you just pour it in!!!!

I would rather buy the mix yourself stuff but i liked the look of the pro cool.
