Transition from ICE to EV


Topic starter

EV’s are on the horizon. No one knows how long ICE will be around. Or how soon EV’s will take over. But it is inevitable. 

What wrenching skills are transferable from dealing with ICE vehicles to dealing with EV’s?

What are the parts and components from ICE that will be common on EV’s?

What parts or systems from ICE will no longer be needed on EV’s?

There will be a fair amount of items in ICE that will transfer over to EV:

  • suspension (i.e. springs, struts, shock absorbers, control arms, bars, linkages, bushings, joints, etc.)
  • alignment will still be needed
  • brake system (brake pads, rotors, calipers, including bleeding) - although you won’t wear these items out as much since EVs will rely on one pedal driving to slow down, so you will hardly need to use your brakes.
  • brake fluid and bleeding brakes
  • wheels (and wheel hubs)
  • tires (and rotating them every so often) including TPMS;  knowing how to change a tire, fix a flat still applies
  • EPS (steering) 
  • ADAS (driver assistant - lane change, adaptive cruise control, cross-traffic alert, blind spot detection, etc.)
  • wipers and windshield wiper fluid
  • cabin air filter (still need to change that)
  • cooling systems (to keep batteries from getting too hot) - you will need to change the coolant from time to time
  • battery
  • windshield and glass (and how to replace if cracked/broken)
  • infotainment 
  • electronics 
  • horn
  • E-brake
  • Headlight and lights (blinker, turn signal, fog, rear, etc.)
  • body work (if get into accident body shops will still be able to work on them)
  • seatbelts
  • electrical gremlins (will see more of them esp. from automakers that already are not known for reliable electronics and electrical systems)

Most importantly being able to use existing knowledge and logic to troubleshoot car problems will still be relevant, but now an even greater emphasis will be on troubleshooting electrical systems. Mechanics will already be able to address many of the items above but in addition will need the skills of an electrician to more effectively work on EVs as well as safely working with high voltages.  Those that know how to already work on hybrids will be better able to make the transition to EVs.

What will be different (not meant to be comprehensive):  no more complicated engines and transmissions (replaced by motors and batteries along with battery management systems to keep them in nominal temp range), no more exhaust systems (and therefore no need for smog checks in states that require them), no more gasoline (trade for electricity), no more leaks (oil, ATF, coolant), no more blown head gaskets, no more exhaust note (part of the experience in owning certain ICE).

Thanks for the detailed analysis. Seems like a ton!!

Would like say great detail's! But would like to say coolant systems are still necessary and will probably still leak and instead of oil and atf you are gonna have to put up with electrical goop lol great nonetheless!


It is highly unlikely that this "transition" will get to the point where gasoline cars are gone in my lifetime. (All this by the way is not being driven by customer demand. Car buyers are not demanding electric cars en masse. If this change is "inevitable" it is only  because it is being forced by politicians for no good reason.) I personally have no plans to ever purchase an electric car so I don't really have a pony in this race. The young guys and gals out there will have to deal with it.

Getting back to your questions, the most transferable skill from today's vehicles will be working with electronics. However dealing with them will likely be beyond the ability of the shade-tree mechanic, much as complex electronic systems are on today's ICE vehicles. If you do want to service them you'll need electrician training so you don't electrocute yourself. You won't find fuel systems, exhaust systems, cooling systems (at least not the type in ICE vehicles), starters, filters (except maybe for cabin air), or emission control systems on electric cars. You still will have body and chassis issues to deal with as they age.

My assumption for this question was the 2035 deadline imposed by government.

Yes, that's what I meant by the transition not being driven by market demand, it is being forced by the politicians. Just a simple statement of fact since obviously this is not the place to argue about the politics of it all. However that deadline is only for the sale of new vehicles, not to remove existing ones from the road, plus a lot can happen in the intervening years so we'll see how it actually goes. (Scotty has talked a fair amount in his videos about the problems with electric cars as they exist today. Perhaps by 2035 we'll have Mister Fusion?)


From my perspective since I'm about Scotty's age by the time that there are actually no more gasoline-powered cars on the road I'll either be gone or so old that driving will be the least of my problems!



All the stuff related to engine and transmission , basically all the powertrain stuff, will be gone. The AC/heat system will be completely changed. All the fluids, but the windshield washer and brake fluid, will be gone too. 

Some EVs, like Tesla and GM still having liquid cooling systems.

Yes. Although it is sort of an internal motor part and I’m not sure if you can change it yourself or you need to take it to a dealer.

The Bolt EV actually has 3 separate glycol circuits. Motor+electronics, batteries, and cabin. People will eventually figure out how to do it themselves.


I'd say the average shade tree won't be able to fool with them. I have a Cadillac ELR and other than changing the oil I won't touch anything else, it's WAY beyond my limited skills. Touch the wrong thing and that battery will send you off to the next life.

doesn't the power source have a main breaker?


Not really a specific answer to your questions but the transfer is pretty soon in some places. Some cities in California are shooting ban new gasoline car sales in 6 years, 2027, and in the whole state by 2035.

So I'll be in Nissan Leaf taxis in college!

Toyota plans to have ALL of its line up offer Hybrid/EV/PHEV by 2025 and have around half of its profit from those.
