How many 1-way brake vacuum valves are there on a 1999 Saab 9-5

4 cylinder. There was one about 5" on the line going to the vacuum pump pointing to the vacuum pump, and another one on the same line about 24" away towards the engine. The one by the vacuum pump had the word "motor" and an arrow pointed towards the v.p., and the one closer to the engine had the word "motor" on it and an arrow pointing toward the engine. Are they both supposed to be on there, and are they supposed to be pointing in the direction I listed? Thanks

SOURCE: Refitting Saab 9-5 Turbo

The turbo is located on the front cylinder bank, under the engine cover and heat shield. The exhaust turbine housing is integrated into the exhaust manifold so this entire piece must be removed. Contact me via email and I will provide information on where to get your turbo rebuilt.

For a regular oil and filter change, 4 liters or 4.5 quarts.

SOURCE: front wheel noise whilst driving

Yes it sounds like a wheel bearing.I would jack the suspected wheel off the ground and then grab it from the top and bottom and then try to move it with a push and pull movement.If the wheel moves that is most likely the bad one.I would also try the other wheel just to be sure.The bearing isn't to bad a price but the bearing needs to be pressed in and out to be replaced.

SOURCE: I have a Saab 9-3 TDi 2001. The engine warning

Hi
If your engine warning light has come on this is indicating there in a serious problem and the limp mode has been switched on to safe guard the engine. It could be a number things, but I'll give you some basic things to look at which may help you.

  1. Check all fluids are are the correct levels - engine oil, radiator water level in overflow tank usual beside the radiator.
  2. Also check transmission fluid level if it is an automatic, from the dipstick.
If all these are ok then check these areas:
  1. Air Filter and housing has no blockage.
  2. Fuel filter may need replacing or water separator is filled with water, loosen valve at the bottom of fuel filter and drain the excess water. Fuel should not come out just water if there is any.
If all these are ok then there is a problem regarding sensor faults, fuel pump timing, and further in depth diagnosis will be needed. Hope this is helpful, let me know how you get on.

My 1997 saab 900s brakes need to be pumped sometimes in order to get the car to stop any suggestions?

You need to bleed the air out of the 4 brake lines.

Bleed valves are attached to the caliper housings at each wheel - 10mm wrench should do it!

Be sure to attach clear tubing to the bleed valves and put other end into a clear container with some brake fluid already in it. this is so the brake lines don't suck air back before you close off the valves.

Close the valves when no more air bubbles come out.

You will need someone else pumping the brakes for you.

Before you start, open brake master cylinder and have a can of new brake fluid handy to refill reservoir as you go.

Start with wheel farthest from the master cylinder and work forward.

Oil in brake booster

The vacuum is created via a mechanical pump driven from the cam, Or a separate, electrical pump.

The only liquid I have ever found in any servo (booster) is brake fluid from a leaking master cylinder.
If the vacuum is low/absent, due to a faulty cam driven vacuum pump, and crankcase pressure rises, along with a faulty one-way valve in the vacuum plumbing, it's possible the oil could be forced into the servo housing, and operating the brakes would help it happen as the servo could act as a pump itself and draw oil from the engine.

Found some diagrams:

Excessive force needed to apply brakes. Master cylinder full. Power has gone out of the power brakes.

Look under the hood and on the driver's side at the booster behind the master cylinder. Check to make sure that the vacuum hose is still in tact and not damaged. If this is fine, replace the booster. What this item does is amplify your push by using vacuum to pull a diaphragm and push the rod into the master cylinder. If the diaphragm is damaged internally(no vacuum), you will need to push on the brakes like an old world war 2 duece and a half to stop. Let me know if you need anything else.

Press brake peddle almost to the floor and it does not stop.The mechanic says it is the master cylinder. Possible or not likely?

If the pedal has sunk further than usual or gradually sinks then usually a Master cylinder gone bad, but also can be a ruptured barke hose or line. It can also be leaking brake caliper or wheel cylinder (will show a fluid level loss in Master Cylinder)

2000 Saab 9-5 wagen - engine stops

Sounds like your CPS (crankshaft position sensor) is defective. It is a cheap sensor $75ish and only takes 30min max to R&R. Both the 4 cylinder turbo and 6 cylinder turbo have this sensor (different sensor, same concept) You can also check the function of your FPR (fuel pressure regulator) by sucking on the vacuum line attached to the intake manifold. It should hold vacuum without leaking down.
