Coolant is life of the car.

What you don't know about coolant is that in EV's - the system is sealed and the coolant doesn't get hot. They also use the AC to keep temps under control. Unlike in a ICE car the coolant doesn't go through a very hot engine. As far as I know, in normal operation typically it sits at barely above room temperature (typically 20-40). I was amazed when I touched a cooling pipe on a friends EV after they had driven some way to meet me. It was room temperature and the hose was soft because the system wasn't under pressure (although I'm told they are sealed and will pressurize).

From what I've read if you are hot lapping the nurburgring they can get hot. Fast charging the AC system controlls the temp.

Corrosion is massively accelerated in an ICE car by the temps. So I guess in an EV they seem to last.

So coolant lasts virdtually indefintely. It's a new world..

I posted the below chart a few days back in here. It's been a bit of an eye opener to me.

We've managed 10% of EV's for a couple of years now - and emissions are still rising. Our vehicle fleet is big, and a few hundred thousand EV's combined with our absolute insistence on diesel dual cab utes and possibly population growth mean we're going backwards!

I tender this article on the NVES. It shows it's going to be bad for manufacturers. Some of them might want to increase prices. Perhaps a ranger could have a bill of 3700 per car. It sounds a lot - but will that be enough to discourage people from buying a dual cab ute?

I actually don't think it will. In the scheme of an 70-100k I don't think it will be deal breaker.

In reality it's more likely ford will buy credits and sell a few EV's so that will reduce it a bit. So will the NVES make a difference to that chart below. I don't think it's going to be enough.

So there are only two ways we fix transport emissions. We persuade people to drive EV's or to just not drive (ideally!). IMHO we are going to have to do a lot more to encourage people to make better choices. And the longer we put it off the harder we are going to have to go.

PS If you don't like the two options above you should be encouraging everyone else to consider their transport choices.
