Indeed. And I never had my old BB Chevy spin the p/s belt off. Nope. Never. Didn't happen.
Alternator belts are the ones that cause all the problems. A well maintained car will never spit a waterpump or P steer belt unless it has failed through old age,,, or is also driving the alternator. Many engines share the waterpump and alternator on one belt. The alternator is what causes them to do silly things. Disconnect the charging system from the alternator and use it as a belt tensioner and most of the problems go away.
I have sold and serviced cars and commercials for a long time and the alternator belt and alternator is what cause the problems.As well as poor eaths which sometimes fool the alt to charge flat out, or not charge at all. On most brands of cars. They cause more problems than AC belts and drives. The humble PS belt and pulleys seldom cause any grief in comparison. On road cars not beyond annoying usually with squealing belts upon start up and sometimes belt noise too. Though broken brackets are not uncommon at all on many breeds of vehicle. Every belt failure I have experienced in 20 years has been alternator. Though sometimes they will take the others too. The modern serpentine systems which drive everything are a worry sometimes. I have watched them on dyno runs whipping and literally smoking around the alternator but not the other drives.
As for the EPAS not consuming power think again, all cars are constantly weaving driving down the road, worse roads do it more. Think about what you are doing when driving, constantly correcting against road camber, bumps, around other traffic. Try letting go the wheel for more than a few sec and see where you end up. HPAS is hydraulic power, EPAS is electric power which has to be replaced to the every increasing battery size by the alternator. Which will need to be larger [consuming more power] to run another accesorie. Some off roaders are already fitting two alternators of slightly smaller size to make life easier for drives and too have a back up charging system. Especially with two batteries.
Plus the increasing reliance on the electrical system is hardly ideal as a limp home out in the sticks.
Scarey moment for myself,, out in the Queensland channel country a 150 miles [and about 4 hours] from anywhere, do a creek crossing which are about every 4 km and the alternator stops charging,,,,,,oooh shit. Turn everything unnessential off and we are not stopping. Luckily about 1/2 hour later it started to charge again. So while it was a bit tense back to normal. IF the Landcruiser had EPAS that would have been another heavy current draw. The ignition actually draws very little. Even with 2 big batteries the ign, EPAS, brake lights, wipers, 4wd functions would be making the batteries very sick. Two days later on that trip, a1000km on, it actually spat the alternator belt off. And that was new the week before. Put the spare on and continued again with reservation though by then we were in civilisation,, no more than about 40 miles between homesteads. And regular traffic every hour or so.
So do we really need to put all our eggs in one basket just for park assist? I dont think so!
As a matter of interest too. Quite a few racers and hotrodders have gone to electric waterpumps. Most only pump at one speed, usually too fast so are another cause of overheating. A speedway sedan I was associated with fitted one and did not finish a feature race. And the fresh engine was decidedly lazy well before it should have been through being overheated too often. AND it kept flipping the alternator belt. On one occasion taking the PS belt with it. Standard Ford brackets [which have been known to break also] just with a bigger pulley on the alt to slow it down.. In the end after my harping he put the std waterpump back on, suitably slowed for racing and no more overheating! And when the alternator belt turned itself upside down three races on one night we put the simple belt back on between crank and pump and no more grief . For about the remaining 4 shows for the season.
