As an aside, I find it best to check the coolant level at night, a dark garage would do, if I had one!

If you remove the coolant bottle cap and shine a light into the orifice, the level shows up much better than trying to do it in daylight.

Now we seem to have got into coolant issues, can anyone tell me if there is a ( relatively easy ) method of changing the coolant without special equipment to refill, so that you can be sure there are no air locks - I assume this is why BMW use special equipment- or say they do in the manual.

It needs to be vacuum filled, kits are available on Ebay.

You don't say in your profile what bike you have and it (maybe) makes a difference.

The VERY early K12's had a bleed nipple on the top right hand side of the head. With the bike on the side stand it was 'possible' to fill the bike and bleed the air out using the nipple.

I say 'possible' because although mine had it, when I needed a new radiator I chickened out and paid £50 for the vacuum kit. I already had a compressor!

I guarantee that every BMW dealer uses the vac kit! I can't guarantee that they use it properly.

The problem with not using the vacuum method is you get air pockets in the head which cause hot-spots in the head and this can lead to cracking. Lots of cases on t'internet of DIY folks complaining about it back when it first became common automotive practice. I doubt any of them were BM owners  8)

It is an early k1200s and does have the bleed nipple. For safety it is a vacuum kit then I guess.

Now would be a good time to include your Model and year in your profile Graham, this demonstrates why  ;D ;)

Very neat kit, being designed 'flat'. Mine is a clumsy three dimensional thing which is in a 'huge' box.

If you haven't hit the 'buy' button yet, one caution is that you need a small (conical?) adaptor for the radiator cap orifice.

A lot of car kits don't have the small adaptor!

I'm not buying one just yet, I still need to get my radiator dirty and then time to fall apart before replacement and then refill
