Is the Halfords premix stuff ok, or does it have silicates (reputed to screw the water pump) in it?

If no good, what is? :O

Just keen to get it back together again :)

Silicates are basically bits of sand and slightly abrasive. They do some good but I don't remember what it is. The green stuff usually has a small amount of them in it (but not enough to hurt anything imho). The red/orange/yellow stuff usually doesn't.

I use Halfords stuff, there are 2 types............one more expensive than the other & you can't mix the two together, can't remember what the diff' is. I use it in our cars and the Tillis, still change it once a year tho'.

Never had to change any on any of my bikes but i do remember reading a while back that the coolant must be suitable for alloy engines or it can cause corrosion inside. I think thats right:O

I've just flushed my rad and used the expensive Halfords coolant. Mix 50/50 (max) with distilled water. It is suitable for aluminium heads. Best bit is that it is a lovely fluorescent pink.
