In a truck equipped with hydraulic power steering, is it necessary to check the steering fluid level?

Question

DentroTest · Accepted Answer

In heavy vehicles with hydraulic power steering, the hydraulic fluid transmits to the steering mechanism the assisting force generated by the pump. For this reason, as part of preventive maintenance, the fluid reservoir must be checked periodically and the level must be kept between the minimum and maximum marks on the reservoir itself or on its dipstick. You must not wait until the steering wheel becomes hard to check it, because driving with an insufficient level can damage the pump and compromise safety. Nor should you fill it until the fluid overflows: the level must stay between the marks, since the fluid expands as it heats up.
