Not the A/C cooling system. In The Ford Lightning forum they have said there will be two coolant systems. They have been very quiet about: checking the level, frequencies, how that’s done ie where’s the dipstick, special equipment required, what is “the fluid” ie ethylene glycol… Only real info so far is to replace “the fluid” at 200k miles. Is there any information on the Silverado EV coolant systems at this time?
