1994 Saab 900s How to tell if I may have a cracked radiator

Radiator, water pump seal, overflow bottle? How much fluid left in the rad? If it's a rad or water pump, cheaper replacements should be possible. The other thing that will cause it to overheat is the thermostat... if you can get heat inside the car when running, it's probably okay. A bad pump seal will leak pretty quickly, and should be easy to see when the car is running. Get a rebuilt one!

When i first start my car theres a high pitched whining/whirring noise on saab 900s, what is that? starter problem or a belt or pulley?

The accessory belt idler pulley bearing is on the way out. Get it replaced. You will not be able to drive the car if it fails, since that belt drives the power steering, water pump, and the alternator.

I replaced the water pump of my 1995 Saab 900 SE. Since I was there already, I replaced the spark plugs as well. After that I noticed the engine runs rough especially going up hill. All vaccum lines...

It sounds like you may have a vacuum leak at the throttle body, inlet manifold or associated hoses. If there is no leak, recheck the spark plugs to ensure you set the correct gap on the new spark plugs.

My 92 Saab 900 blows cold air constantly and the temp gauge stays on low. I replaced the thermostat but still no change. When the heat switch is off for a period of time while driving I can turn the switch...

Unless you have symptoms of over-heating, I rather doubt that your water pump is a problem. I recall that my water pump had a metal impeller (1992 C900); I haven't heard of a plastic impeller on a Saab pump before. (Most pump failures are the bearing seal, and the pump leaks coolant) If your temp gauge is slightly low (and was OK before) I'd rule out water pump issues.

You might have one or more of the following issues:
  1. did you use a Saab thermostat? The Saab stat has three stages (no flow to rad - cold; flow to rad and heater core - normal operation; and no flow to heater core, full flow to rad - overheating) that most after market stats don't.
  2. did you use a low temp stat? this opens at about 82 deg (rather than 89 deg), and will run cooler during the winter, hence you gauge will show lower than the mid point. The big benefit is that your engine won't overheat during the summer (a very good thing!) with the low temp stat.
  3. has your rad and heater core been flushed recently? If the heater core is obstructed flow will be reduced and the heater will run cool. Feel the rad and heater hoses when your engine is warm; if heater hose is much cooler than rad hose with heater temp set to max, then core flow is likely restricted, or valve is not moving much from the shut position.
  4. is you vacuum tank properly connected and are there no leaks in the vacuum piping? The tank is in the driver side rear wheel well below the trunk deck on a convertible, and in the passenger side front fender area on the other cars. It's a white bottle with one or two hoses connected to it. If not properly on, your vacuum operated heater flaps won't move. Does the air distribution knob make sucking or hissing noises when you set it to different positions? If not, check the tank connections, look for vacuum line leaks, then suspect the vacuum valve behind the distribution knob.
  5. Lastly, the shaft connecting the temp control knob to the valve behind it may not be properly in place. This can be inspected, and adjusted if necessary, from the speaker/vent cutout on top of the dash. Make sure you re-connect the black flex hose to the air vent tube, or you'll get no defrosting afterwards!
  6. remember, the centre vents always blow cold air; a brilliant idea from Saab so the driver (and passenger) can get fresh air in the face and stay awake while the rest of the driver, passenger and car is toasty!
  7. see for flushing and stat replacement info

I need an engine diagram for a 1995 saab 900 se V6

A SAAB dealer should be able to print one out for you. BTW that engine is practically identical to the V6 used in a caddy Catera, and Saturn Ion. Those diagrams would be the same, so you might want to search that also.

2.3 900 se fan belt

The Saab fan is electrically controlled directly via the ECU and has no belt. I will therefore assume you are referring to the accessory belt that drives the power steering pump, the alternator, AC, etc. Pictures and step by step instructions are here and here. Both of these sites are also demonstrating the use of a shorter belt to bypass a center idler pulley that fails frequently (and that was eliminated altogether by Saab in the transition from new generation 900s to the first iteration of the 9-3 model).

I need help with my water pump in my saab900-sport.

The water pump is located at the firewall end of the engine. If your car has A/C. it makes it a little more difficult, as you'll find the compressor is in the way and difficult to work around. ONLY if your A/C system is empty, could you disconnect the hose to the A/C compressor. Otherwise you might consider disconnecting the entire compressor from the engine (but not opening theA/C sytem so you don;t loose the gas) and moving it out of the way if you can't work around it.

There are four bolts holding the pulley to the case; loosen these then remove the drive belt(s). The belts hold the pulley steady while you loosen the bolts.

Remove the pulley completely.

Then remove the bolts holding the pump to the case; NOTE the position of the longer bolts - you'll need to reinstall these in the same locations!

Install the new pump in reverse order; make sure you use new gaskets.

Penetrating oil liberally sprayed on all bolts before removal eases the work.

Good luck!

1995 saab 900 runs fine and then all of a sudden shuts down completely. I can pull off the road and restart and it will run fine. It may run fine for 100-150 miles before it does it again. There are no...

Try this simple solution,
Buy some fuel conditioner additive from auto parts supplier, to clean out any water contamination in fuel, run through a full tank and then replace fuel filter.
The fuel pump on the model has been known to stop when it comes in contact with water, so it may fix your problem.
All the best..
