Hi, I have a 2000 Saab 93 SE convertible and the driver side 5th bow cylinder is leaking badly. I have already replaced it with one i purchased from a savage yard. When I got the one from the salvage yard I check to see if there where any fluid leaks in the trunk, under the back seat and the drain cover but there was none.
1) Is there a way to see the leaking while the motor is operating? I would like to check if the hose itself is leaking. 2) Should i risk buying the $500 new cylinder, I affraid that it may fail too. I thinking maybe something is causing them to fail. 3) Is the any other fluid I can use the oil is $35 a bottle!
Well, you can check the cylinder when the motor is running and the 5th bow and tonneau cover is in the opened position. Sweating of the cylinder is normal, that means that there is film of oil on the piston. Drops are however not normal and means the cylinder is leaking.
A new cylinder would possibly help your situation, since there was a change done to the cylinders to eliminate leaking. This was done in 2001-2002.
Check also the kinematics and the axles of the cylinder and check that the cylinder and hoses have enough freedom of motion. Most of the leak cases occur because of transversal forces acting on the cylinder and piston.
The hoses very seldom leaks when propoerly assembled.
Its recommended to use the same oil. You can get it from another store, for instance Ferrari is using the same oil and I think in some cases it is cheaper than at the Saab dealer!
Hope it helps.
I used your advice, I had my son sit in the drivers seat and raise and lower the 5th bow. I immediatly saw the leak. It was a pin hole in the hose. the fluid was leaking down and under the car forming a pool of liquid near the front. (how odd). I later deteremined why because my driveway is on a sharp incline. I could not find a way to replace the hose so cut it, placed a small metal breakline connector then clamp both ends to it.
I check and check and the leaking has stopped.
Thanks for the info on the oil but I don't live near any Ferrari dealers. So I purchased from GM it is the same oil for the SSR $29 still cheaper than SAAB.
Also, if anyone is interested I have 4 remaining hydraulic cylinders remaining and I will gladly sell them cheap.
