- rpcope1 1y agoSounds like the Colorado. It's a reason they'll pry my S10s, GMT400 and GMT800s from my cold dead hands as they're more reliable, cheaper to service and easier to service.
- trashb 1y agoDon't forget one of the latest automotive mistakes, the "wet timing belt". This is a rubber timing belt (not a chain) that runs through your engine oil disintegrating and clogging up your oil filters. If anyone here owns a car with that system I recommend taking it to your trusted mechanic and discussing with them to do additional preventive maintenance on it.

- warmwaffles 1y agoA lot of 4 cylinders and the Duramax 3.0L engine. The claim is that these belts reduce noise because chains are "loud".
- CamperBob2 1y agoWow, yeah, it looks like the Duramax engine has a 15-year belt replacement interval that costs $10K at today's rates. They aren't even trying to hide the whole planned-obsolescence thing at this point. Average age of cars on the road is approaching 13 years now, so someone who buys a Duramax-based vehicle will end up with a metal and plastic brick that costs more to maintain than it's worth, just because of the timing belt alone.

- supportengineer 1y agoThat is the worst idea in the history of ideas
- warmwaffles 1y agoIt's 180k miles. It's the 3.0L Duramax because the oil pump is on the backside of the engine using an oil submersed belt rather than a chain or set of gears. So you have to drop the transmission, exhaust, oil pan, and take the back side of the engine cover to replace a belt that should have been a chain. It _may_ be faster, to simply disconnect everything and pull the motor. Source: I own one of these engines and I dread having to pay ~3k for this maintenance in 3 years. I like the engine, just not this maintenance ticket item.
- hadlock 1y agoIn the 1955 Citroen, standard French family car of the era, the timing chain sits behind a cover about 1/2" from the firewall, the whole engine has to come out to change it.
