    Leaking 3-way valve

    I just purchased a used 2015 85D and after driving with the heat on, found a small puddle of coolant under the front of the car on the passenger side. It only appears when I run the heater (which is why I suspect the previous owner never noticed it as he was in a warmer part of the country)...

    Hey, I collected my M3P on Monday and today I got in the car to see a "coolant low - contact tesla services" warning. There is also what looks like a leak under the car.

    Battery coolant does not need to be replaced for the life of your vehicle

    This was posted in the Model 3 forum (and I mistakenly replied to it), so I thought I'd post it here for Model S owners to see. The new MODEL S OWNER'S MANUAL (2019.16.1.1 dated May 16, 2019) states that "Your Battery coolant does not need to be replaced for the life of your vehicle under most...

    Vehicle Coolant is Low - Contact Tesla Service

    So my S (Dec 2017) has its first service yesterday as it was coming up to 12,500 miles. Apparently they don’t do drive unit fluid changes at the first service anymore even though their website states they do but I digress. It was fine driving home after collecting the car (8 miles) and a round...

    So I would like to explain everything I understand about Model S (very likely Model X is similar) thermal management system. Number in yellow is slightly to the left of the object it refers to.
