Yeah, people too often say things like "there's no gaskets" or "there's no gears or oil". There are gaskets, there are usually gears, there is usually a lubricant oil in the gearbox. But the temps and pressures on the cooling systems are much lower, the gearboxes are fixed gear ratios, and there's no waste carbons in the oil dirtying it. So the service intervals of all of these are much longer than any regular ICE vehicle.
