Tesla Maintenance

[Torrid]

Then there is this..


Other things of concern are flow erosion and electrolysis which in an EV or hybrid may be the greater concern as the vehicle ages.

This is not about ev it is about coolant/antifreeze. posters have stated it is all about pressure and because the ICE may produce more heat and more pressure (I don't really buy into this theory) the Tesla does not need as much if any servicing of its cooling system.
How much heat does the EV electric motor generate under operating load, how much heat is at the main battery that the cooling system has to absorb to keep it at a lower temp? I find this interesting but also don't buy it 100% either.

I would agree with you on that last point. It may be true that less heat and pressure may extend coolant life, but I would still always preemptively replace coolant as cheap insurance. In other words regardless if it was true or not, I'm not going to have to find out. I've always refreshed coolant and brake fluid regularly while the average consumer does none of that.

I learned that formula in HS Chem, perhaps 1969. For the life of me, I don't remember learning it applied only to gasses. I learned something today!

That's pretty advanced for HS Chem. I think I only learned about the universal gas law (and its derivatives) in undergraduate engineering.

It applies when everything is a gas and stays a gas. That's why you want dry air (or Nitrogen) in your tires.

I change brake fluid when caliper(s) fail. In New England our VW Tiguan rears lasted 8 years/210k and started leaking fluid .

Our Math and Science departments were stellar. Chemistry was probably the toughest, Physics was more of a survey.
Nowadays some students are studying Calculus in their 2nd year. Crazy.
