Its a fairly easy DIY and the cambelt kits including water pump are relatively cheap say about £100.Thanks guys for the input & advice
Why-oh-why can't they put chains on the diesels like they do on the petrols ?....rubber belts make the engine a couple of lbs lighter, but they increase the customer servicing costs !
Chains arent foolproof..on the 9-5 petrols they wear and can need changing before 100K depending on your luck and its usually an engine out job to do it thoroughly changing guides and such.The engine are all interference diesel or petrol.
Anyway, I much prefer the last Saab to any Merc E-class....it's got so much more class, looks & leg room. Considering it's the same engine as the Vauxhall Insignia, then a cam belt change every 75K miles may not be so hard on the wallet.....just as long as the cambelt is strong enough to last the distance that Saab state.
A chain or belt can fail at anytime its just less likely the more often you change. I think Saab originally specified 100K but that came down to I think officially 72K for the belt.
cjapeterborough....I'm assuming that this engine is an interference engine (most are nowadays), so having the belt snap will most likely make the valves slap against the cylinders & cause major internal damage....right or wrong ?
The rockers above the hydraulic lifters are designed to fail (ie snap) if the engine suffers a belt failure so usually a rebuild is cheap ie say you break 50% then 8 lifters at say £40 pus labour and cambelt kit etc
Just out of interest, does anyone know how much it costs for a cambelt/water pump change ?
The engines don't regularly snap cambelts before they hit 80k miles. The problem is, that for many folk, basic essential maintenance just goes out of the window, so belts that should be changed at say the 5 year point, it gets missed or forgotten, or the owner sells the car on before they have to spend the money changing the belt/tensioners and waterpump. And of course then there's no record of the job being done, or you have car resellers claiming the belt has been changed when it hasn't. For lots of owners, even changing the oil and filter is just too much hassle!A friend of mine has a Vauxhall Insignia 2.0 diesel & is having the cambelt done next week at 95K miles....dealer recommends change at 100K miles.....So why does the Saab 9-5 with the same engine have to have a new cambelt at anywhere between 40K & 75K miles ?
I think some people on this site are being a little over cautious.....treating the car like a fragile puppy ?
To be honest, who would be fool enough buy a diesel car that was renowned to regularly snap a belt before it hit 80K miles
