Do they really need to > be replaced every 15K miles? 3 things: 1) an 85 C900 is a different animal from a NG900. Did any C900 2) I would replace the belts every 30k miles and check it every 15k per the SAAB recomendations / schedule. 3) I would replace the idler and tensioner pulleys at every second belt change since the wheel well liner is already off. -- -Fred W
