Curvy coolant
 

Ok had a look at the coolant bottle and i carnt see anything in it!!!!!!!!

so im sticking some more in tonight but i need to know what spec coolant it is. OAT or glycol?


Any ideas?

Its the same as all coolants you get at bike shops... Though make sure you fill it from the reserve under the tank. Also as it can get a bit dirty sometimes its a bit hard to see what coolant you have, so I added some blue food colouring to mine to make it easier.

but if im getting it from halfords which would it be.

ok blue or orange?

:)

Re: Curvy coolant
 

Any modern coolant suitable for aluminium engine blocks should be fine. Almost all of these are glycol based. The question is what did the person before you put in there?

I've generally used the standard Halfords blue coolant, mixed 50-50 with water.

thinking ill get the oat stuff then as its 5 years between changes and should be compatable.

Its nice and easy to do, I had to do mine when the rad sprang a leak and the bike overheated in December.

If it hasn't been changed recently why not take the opportunity, it's very easy on the SV, no issues with airlocks etc. Just drain at the water pump bolt, and take the make-up pipe off at the rad cap end and drop it down to drain the bottle.

I use a silicate free variety due to the generally improved seal durability, I use Toyota Red coolant (not the latest ultra long-life pink stuff which costs an arm+leg), it comes ready to use, somewhere round £4/litre but good for 5yrs so fairly cost effective and in my experience a good coolant (based on my Toyota, changed the coolant in that at 7yrs and it was nice and clean and didn't smell like some do). Their Red is definitely slicate free, specified for Japan built engines.

Most long-life varieties are OAT based now I think (may be wrong :-?).

just don't overfill or your SV will overheat and have a blue wee all over your patio:-(
