My power steering has never been quite right, on full lock the steering wheel would pulse quite heavily and the pump drive bel t would slip a little bit. Now the belt is really slipping and i have left it that way because i think there must be a pressure relief valve or something that is stuck? This being the case i would rather have a slipping belt then something else letting go....

am i right in my assumption about a pressure relief valve? if so where is it and how can i unstick it?

Thanks as always

Mine used to pulse on full lock with the belt slipping. I changed the belt and now everything is as it should be. Bit of a pig to do though.

Ahh, so you are saying that the steering is pulsing because the belt is slack? it seemed really heavy though

Also, if the belt is gripping enough to make the steering pulse at full lock doesn’t that meen that it should be releasing the pressure somewhere?

If your belt is slipping its for two reasons, firstly and most likely, your belt is knackered and secondly your pulley is knackered. There isnt a relief valve in the power steering circuit.

Pulsing isn't a pressure build up, its a pressure loss as the belt slips. Full lock is the point of highest pressure so that's where it will occur first

The belt is a serviceable part, like oil and filters after every few thousand miles or so.
