Help! D5 non start
I have a Volvo XC90 2008 D5. Yesterday I drove the car quite a bit. I noticed a new intermittent noice that would last for about 10 seconds, it almost sounded like a air leak or wind blowing into a plastic bag and when I revved it would get louder and then stop and the car would still run perfect.
This morning I tried to turn the car on and nothing. It has a very weak slow crank although the battery is at 12.7v. Starter has also been tested and is perfectly fine. There is a loud squeal coming from aux belt pulleys but they do turn slowly when cranking the engine. Tomorrow I am going to try turn the engine over by hand and hope it turns. I was wondering if anyone else has had a similar problem and can tell me the best way to approach this and possibly lead me to the problem. Thanks Last edited by Darrenw; Dec 28th, 2021 at 23:31. |

Have you observed what the voltage drops to when attempting to crank/start?

Ac compressor
I took the belt off today and the ac pulley wouldn’t move by hand but the clutch would move freely. I also noticed that the 6 ribbed belt is now a 5 ribbed belt so it shredded. Luckily it didn’t hit the timing belt or get caught under the pulleys. I am assuming it shredded because of a seized ac compressor pulley. I have ordered a refurbished compressor (with warranty) from a seller on eBay. I was just going to buy a replacement pulley kit but looks like a fiddly headache and requires tools that I do not have, so I believe that buying a refurbed compressor is best.
Will keep everyone updated if you are interested. Thanks for the help. |

I found most of the rib I think the rest has just snapped and on a random road somewhere. I checked all pulleys and tensioners and there was no damage or lodged belt ribs. I started it and let it run for a couple minutes and it ran fine. When I tried to start it again it didn’t start but I believe the battery just doesn’t have enough power now because I cranked it so much when it was struggling to start to try find the problem.
