    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    It's all relative I guess! We had cell service; I have a quality coat and waterproof pants packed; no footwear though! I also have blankets and towels!... Having kids was the hardest part.

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    Absolutely agree, unfortunately I don't know the complete history so I'm working my way through everything as I can. I was planning to do the water pump as part of the bigger overhaul (timing chains, crossovers, water pipes, anything else I can figure while I'm in there). So my plan is to...

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    Should know more later, I wasn't able to get to it last night. The passenger side idler runs very smoothly... It has me thinking that these bearings could have been in there for a while. As soon as I know more I'll post back. Thank you.

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    Yep will do, won't get to disassembly probably until tomorrow evening. So far the passenger side idler feels OK, as does the alternator, I didn't get to test the other ones yet... Will report back. Thanks.

    No idea! It's the passenger side of the crank pulley, will know more when I start pulling things apart!

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    Belt is mostly gone, there are bits of rubber all over the place and a few remnants of longer strands! There was no belt squeal, there never has been... It's always run very nicely until Saturday; it could be that the belt was old, my line of thought has been to get in there this fall and...

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    The noise was more like the broken belt wrapped around something and rotating/slapping something else or potentially knocking on the fan. There was no warning, or any weird noises prior to the failure. I did read about AC compressor locking up; I'm hoping it's not this! I've yet to get in...

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    Thank you, keeping my fingers crossed! Luckily we weren't on a highway going fast so I'm hoping it's OK. The model is a 2012 LR4 with the 5.0L V8 and 102,000 miles. On my radar (as mentioned in previous posts) are the timing chains and crossover pipes... I will double check the pulleys and...

    Serpentine/Accessory belt failure on a very wet, dark MI road in the middle of nowhere...

    We had an interesting night last night, having just gotten the truck back on the road after replacing the transmission fluid! I decided to take two of the kids and a friend out for dinner; I like to explore new places and so we ventured out. During dinner we got hit by a huge thunder and...

    Transmission taking too long to shift

    The next step is the refill procedure, for this I followed the ZF procedure (which I condensed in to a document I can share if needed). In essence: Fill with ZF Lifeguard 6 fluid until it comes out the fill hole; initially this was about 1.5L (which I knew was not enough) so I installed the...

    The job is done! Here's the next part of the puzzle... To change the mechatronic valve sleeve I started a new post; details on this job and how I did it can be found here...

    Is this a sensor or an existing dash cam?

    I'm sure Haynes make a good manual; there are also some workshop manuals floating around on the web. It's good to be corrected by the experts :-).

    Transmission - Mechatronic Valve Body Sleeve (TZV500010) replacement - help!

    This is exactly what I was worrying about, I felt like I needed the reassurance before trying to pull it apart! Doing the rear suspension valve is also on the list of awkward!...

    Is this a sensor or an existing dash cam?

    Or AEB (Automatic Emergency Braking), or adaptive cruise control???

    Transmission - Mechatronic Valve Body Sleeve (TZV500010) replacement - help!

    Hey team - it's done. I want to say a huge thank you to everyone for the help. Having faith certainly helped a lot CPalacay... OK, so here are some details for those that follow. I reckon it took me about an hour, this includes getting up and down and trying different approaches at the four...

    Transmission - Mechatronic Valve Body Sleeve (TZV500010) replacement - help!

    Thank you also, I assume you mean this metal tab? If I recall this looks to be the wire for the O2 sensor: I was also wondering if this this one buys me some room: What I'm hearing is this looks worse then it is; how many pints of blood should I expect to lose ;)... My 9 year old has...

    Transmission - Mechatronic Valve Body Sleeve (TZV500010) replacement - help!

    Thank you so much, my confidence has gone up :-). I didn't do any more this weekend and decided to work on other things instead! When you ran the transmission through the gears I'm assuming the wheels were off the ground? I found as posted in my other thread that I can only select 1st and 2nd...

    Transmission taking too long to shift

    Updates from today... I posted a new thread as I'm stuck trying to replace the mechatronic wiring harness sleeve. Other progress: I used a combination of a kitchen sponge and other mildly abrasive materials (including something like a 1000 grit sandpaper - for honing engine bores) to clean the...

    Transmission - Mechatronic Valve Body Sleeve (TZV500010) replacement - help!

    Hi Team, per my other thread I'm in the middle of replacing the transmission fluid on the 6HP28 unit (2012 LR4 - 102K miles). I purchased a new mechatronic valve body sleeve but now I'm seriously questioning if I should replace the existing sleeve (it's not leaking (currently))? I'm really...

    Transmission taking too long to shift

    I started working on the transmission last night! I can now see why it takes so long, esp. as I tend to go quite methodically (read slow)! In many respects I feel I got very lucky as some of it went very smoothly. Here are some notes and tips... I put the suspension in extended mode to give...
