Hey guys,

just recently purchased a 2001 V35 250GT sedan with around 70k on it Automatic Trans.

The car recently started making a high pitched whirling noise and if Ipop the hood on start up it sounds like a giant fan!

If I rev the engine the fan noise and the high pitched whirling noise gets louder, it's quite loud I can just hear it from inside the car with all the windows up.

Help guys!

check belts ! as they might need changing or might be rubing on something. i had a stick that managed to get in and was making weird sounds when touching the belts

Thanks man I checked them and it seems fine, if I pop the hood and just stand in front of the engine the fan wilkl literally start moving my hair, it's very noisy and very loud! Is that normal?

get a hose and spray the passenger belt and listen if the noise goes away.. If it goes away your passenger belt is slipping replace it or retention.

Im betting its the passenger side belt.

The factory belt size imo is to loose on the passenger side to get a decent tension on it.... some belt brands seem better than others aswell. Find the factory belt size and get the next size down. Should be a 4pk925 or something like that for the sedan.

+1 for belts, mine would make a squealy noise on and off during the winter for the first 10 minutes or so, not always on cold days either. Replaced all the belts and the problem immediately went away. It wasn't too big a cost, a good mechanic who knows V35's should be able to do it in an hour.

    • Food for thought, the stock oil filter thread is a 3/4-16 UNF, which has an ID of about 10 to 12mm (according to ChatGPT lol). Now compare than to an 10AN, which has an ID of about 14mm (Raceworks is 14.2mm, Speed flow is 14.27mm).  
    • Yep, totally get that. However hooking in for Generator back up is only a few hundred bucks for the wiring. You could put a couple of those in (for different circuits explicitly) and run a couple of baby generators. Bonus, you can balance them across different circuits, and now have backups in your backup. I'm looking at buying places that won't even have water etc, and I don't mind the idea of getting off the electric grid either, even with everything you've said. This country already has enough power outages that even the mains grid isn't that reliable anymore. I do agree though on spending a bit more to get better gear, and to add some extra redundancy in to the system too.
    • You can set hard reserves on your battery system, and it can't be discharged past that.  
    • That sounds like an excellent idea. But total self-sufficiency means exactly that. You have no-one else to blame when your system faults out and you have no power for a week or two while it gets fixed. You'd have to go the whole hog and get a diesel genny and all the switchover gear, to get you through such times. And, despite the fact that over 20 years, my system has been pretty reliable**, I have seen so many inverter explosions (or less dramatic deaths), panel and roof JB fires, and so on, over that time, to know that the stuff is the same as any other bulk Chinese manufactured stuff. The failure rate is well above zero - both on the equipment and on behalf of the meth addled installation labour force. And then..... warranty and means of redress against the supplier you bought the gear from. Best I can tell is that only a handful of solar companies are still around within 5 years of starting their advertising pitch. They disappear and phoenix like crazy. So, as per 1st paragraph, I suspect the only way to is go balls deep and spend maybe 2-3 times as much as you might think, so that you have every base covered. Plus, know and understand your gear intimately, so you can diagnose problems, sort them out yourself, etc, etc. Plus, probably have to consider upgrading various parts as the years pass, to maintain compatibility with newer stuff, performance and reliability, etc, etc. Whereas, remaining attached to the grid has an ongoing cost that keeps going up even if you use bugger all power from it. But it does provide the fallback in case of the worst case with your own gear. You either pay up front or as you go, I suspect.
    • Add more solar panels to the array. Call the electricity company and tell them you're moving out... Live off grid electric wise
