    The SC called and replaced all three coolant pumps. MS P85 was running fine. I had version B pumps and now have version C.

    The Ranger was great!

    Why did they change them for you?

    The Ranger told me the pumps work fine, but the hardware (version B) does not play well with the software like the new version C pumps.

    Hmn, when did you take delivery? I got mine May 2013. Just trying to figure out who got version b and who got c.

    I wonder how widespread this is and what sort if issues it would cause?
    My two front pumps PNs end in B (third pump is hard to see) and I'm VIN 07822.

    Lordy, I hate revelations like this. No, not directed at montgom626, good to know, glad he posted. What I don't like is the 'who has what' speculation that begins, and the uncertainty that follows.

    That is the compressor for the active air suspension you are hearing.

    I posted this B to C for information only. MS runs the same before as after the coolant pump replacement. I waited weeks to get it done so that my favorite Ranger would be available to do it. There was no urgency, no hurry and no worry.

    I have VIN 16186 and I received a call last week from the local service center to replace all three of my coolant pumps. My car is being swapped for a loaner this Friday. I am in the Phoenix area.

    So, we can assume the TM is just being proactive.

    Just got my vehicle back from having the same pump upgrades. I noticed a new "fireman" tag was placed in the joint/crack on the passenger side. I tried to pull it out, but it seems rather secure. Almost like, pull in case of emergency. I'm at work, so I'll take a look later.

    With the recent things going on, I wonder if these pumps are able to keep a fire under control or prevent a fire due to puncture. In all accounts I've read, there was a few to several minutes after the puncture before the fire started. Perhaps the new pumps can spring into action once a puncture is detected, rapidly cool the battery, and hopefully prevent a fire. Needing to have these installed in all cars with active air suspension would also time out with the next release of software. You may have to have these installed in order to upgrade to version 6.

    All speculation of course.

    Wow that's a lot of speculation....

    My car, a Nov 2012, has had a fireman tag on the passenger side since it was new. It connects to a loop wire that the firemen can cut which disables the HV system.

    The tag has always been there. My Ranger just repositioned it when he replaced the coolant pumps to allow it to be more visible.

    Lol, I was thinking outside the box a little. I asked a couple people why these needed to be changed and still haven't got a straight answer. Just that the new ones are better. Not complaining, but its odd for a company to simply upgrade you because "the new one is better".

    I have never seen the fireman tag on mine before. It must have been tucked under and they pulled it out during this service.

    @phatboyslim, yes, mine was not visible after delivery but every other service they either pull it out or push it back in, depending on how they reassemble the plastic cover.

    Now as for speculation: have you done any 120kW supercharging recently? In other threads this has been linked to extra load on the battery conditioning system with data being sent back to Tesla (via NSA), triggering a coolant pump upgrade ...

    I have not yet had the privilege to use a supercharger yet. I hope to soon though.

    A lot more complex with all the hoses and pipes than I was imagining for the supposed simplicity of this car. Curious where was the picture taken? Under the fronk?

    Yes, the Ranger removed the frunk stuff to expose all the pipes and pumps and wires. The Ranger was a joy to watch.
