Re: [MBZ] OT: Volvo fun
Lesson learned if I ever need to take that manifold off again, I need to pull it back just far enough to unplug that connector, before lifting it up and out. Probably would have been described in the shop manual if I had one, though sometimes they just say something like "unbolt and remove the manifold" On Thu, Feb 15, 2024, at 13:37, Craig via Mercedes wrote: > On Thu, 15 Feb 2024 13:17:17 -0500 Allan Streib via Mercedes > wrote: > >> Well finally got this done.

Re: [MBZ] OT: Volvo fun
Well finally got this done. Waited for a warm(er) day, soldered up all the connectors, which was more tedious than I had expected. Really glad I was able to get the wiring up to the top of the engine bay it would have been a real bear otherwise. That connection is totally hidden behind the manifold when it's in place, it took me about 5 minutes of blind work with my fingertips to get the plug inserted. Got everything back in place, started up, runs smoothly, no codes. Only issue is the MAP sensor connection, the locking tab has snapped off and it doesn't want to stay plugged in. I have a zip tie around it hopefully that will keep it together. On Sun, Feb 11, 2024, at 17:58, Allan Streib wrote: > 2009 XC90.

Re: [MBZ] OT: Volvo fun
2009 XC90. Bought it only because I knew the seller and he had cared for it meticulously. It needed rear wheel bearings, he didn't want to spend the money, and he gave me a good deal. It's been a good car overall. Comfortable, well made, pretty easy to work on overall. It's a two wheel drive model, which in this car is front-wheel drive. The engine is a 3.2 liter inline 6, basically a Ford engine I think, Ford owned Volvo until 2010. Transmission is by Aisin. It tows our little pop-up camper fine. It's probably comparable to an ML320, though I've never owned one of those. Just under 200k on it now. I've owned it since 2018. I was able to unclip the wiring harness in a few other places and raise it up enough so that I can work on it in a neutral standing position. That is going to help a lot. Now I can't find my solder, may have to buy some. Going to finish this up tomorrow.

When you are bent over working on this, just keep thinking about the hourly rate the shop would be charging you, probably including to repair this, even if they, like you, had inadvertently created the problem.

Re: [MBZ] OT: Volvo fun
Guess it's possible. I had the battery ground post disconnected the whole time I was working though, because I knew I would be unplugging stuff and removing the alternator. The plug for the MAP sensor had the locking tab snap off. I used a zip-tie to secure it when I put it back but maybe it's not making good contact.

Didn't end up being too bad. Took maybe an hour to get the intake manifold out, could do it faster a second time. Once that was out removing the alternator was easy.

If it is quite a pain, I would seriously think about replacing it.

[MBZ] OT: Volvo fun
Son was on his way to work this morning in the '09 XC90. He called to state that he had "broken down" and there was a message "POWER SYSTEM SERVICE URGENT" on the dash. I drove to his location and scanned the codes. P062001 Generator control circuit, General electrical fault and P062074 Generator control circuit, Mechanical faults, Actuator slipping. Battery was reading about 8.5V, car would not start. Drove home and got the battery out of my '79 300SD (conveniently it's the same size), went back to the Volvo and changed it out. Car started and ran fine, no fault messages. I drove it home and on the way there was a sudden screeching noise under the hood and the same fault message appeared. That continued for about 20 seconds and then stopped. The message stayed on. The alternator control module (ACM) sends the engine control module (ECM) information on a mechanical fault in the alternator (engine speed exceeds a certain value but the alternator is not operating). Turns out the alternator on this car is not directly belt driven, it's driven by a coupling off the back of a pulley on the serpentine belt path. From what I've read online[1], there is a bolt in that coupling that can back out and then it will slip. So this sounds like what is happening. To get at the alternator and coupling, the intake manifold has to come off. So I'm going to look into that job. Sounds like it might be a bit of a PITA. Suppose I should just go ahead and replace the alternator prememptively while I'm in there? The car has 194k miles and I have all the maintenance history from prior owner and no record of the alternator being replaced.
