I'd like to know too, how you can tell if it's due. Mine makes a funny crackling/squeaky noise when running so I'm worried it might be on its last legs. Being on 135,000 km its way overdue too, just need to save up for the parts and do it pronto.

KIA, More dirt for ya dollar! 99 Sportage, Pod filter, Bosch Super4 plugs, electric thermo fan, racing pedals, Narva 100W driving lights, Yokhama 235/75R15 Super Diggers....getting to the rest bit by bit.
