Non nova but a PAS problem

[novalicous]

My astra van (mk3 low blow) keeps preasureising the power steering fluid up and spitting it back out of the tank

it still works but im not sure what the problem is any one got an idea?

[mowgli]

could be a blocked breather, or too much fluid.. even the fluid or filter could need changine

[General Baxter]

frozen fluid ?

[mowgli]

not thought of that nick, hydraulic fluid does attract water....

[General Baxter]

iv had it all week at BHS, rams completly frozen soild, the oil we use freezes at -25 lol

dont really help that there old and got water in with it lol

[novalicous]

the fluids not frozen andit has the right amount

the only thing i could think is that it has a blockage some where but it would hamper operation though right?

[mowgli]

the trouble is that ice crystals can just jam a joint or a valve up enough to cause problems like this..

Fixed the fault
It were the pump shat the bearings in the pump
