What would happen if you tried to drive without coolant?

I would guess hybrid service will be available almost anywhere in more like 5 years. The same thing happened when fuel injection and computer controls came in. Shops that can't work on a fuel injected cars are pretty much gone at this point.

 

Even doing a lot of things myself, I'd be inclined to get the coolant change done by the dealership. Sounds like they screwed up, should make it right.

 

I exchanged the coolants a month or so ago. The inverter circuit was trivial, while the engine circuit WITH A LISLE FUNNEL is annoying but not a big deal.
