Thread: New Power Steering Pump Losing Fluid

Tweet

I think its coming from the hoses. they do not appear to be dry rotting and I want to say its from the fittings going in the gear box. Should I take them out and put some Teflon Tape around them and screw them back in?

Put the car on a clean garage floor leave overnight, check where the leak spots are in the morning, then look up tp coresponding part of car to find leak, then take action to fix it.

ps: did you prime the pump while the engine was running, and cycle the steering fromm lock to lock a few times to get the air out of the system ?

Steering fittings make their seal by the flare on the end. Teflon
tape or pipe dope will not help them to seal since the threads
on the fittings are NOT the sealing method.

so how would you seal them if it was leaking at the flare mating surface?

(I got the same problem)

I didn't install it, some Goodyear tire place did.

But I'll be sure to check it out this weekend and find out where it's leaking from. Btw.. how much are GM power steering hoses? >_>

Usually, you have to buy a new hose to seal a flare....although some boxes have removable fittings in the box. The flare fittings seal by an contact line just like your engine valves and your brake fittings. One side is cut with an angle...say 45 deg and the other side is made to perhaps 46 deg. When the two are mated, a line contact is established. At this line contact, the pressure is high (since it is a thin line) and the material is deformed slightly to make the seal. If you ever look closely at your brake fittings, you will see a ring or line around the cone on the fitting....this is the contact line. When the fitting is overtightened, the fitting is deformed and leaks since the material is permanently deformed.....this is why the fittings do not require excessive tightening.

Hoses are cheap. You can take your hoses to a hydraulic supply and they can make them for you if they have the particular fitting. Also, the auto supply carries replacement hoses.

Yeah i already have a new master cylinder and brake booster. thats all good.. would it just be a good idea to change those power steering hoses seeing how they're probably original equipment?

I love all my custom made Power Steering hoses. HP and LP. A good investment imho.
