just servicing me rvf and looked in the coolant bottle. theres a tissue like gunk floating about in it.I know it shouldnt be there.
what is it?
what caused it, does it indicate anything major

it is more than likely a build up of shit,corrossion over time

when was the coolant changed last?

drain the coolant,and flush the system as it should be done.refill with 50/50 disstilled water and glycol ethylene anti-corrosion inhibitor(anti-freeze).......

if you have never had any issues with the cooling system or overheating problems then it is almost certainly a build up of crap over the life of the current cooling in the system.


william

dont have overheating problems, ill flush it out and refill it
thanks
