How do you remove the check engine alert on your saab 900se 97?
Support the engine, remove cam belt covers and top engine mount. Remove serpentine belt then crankshaft pulley to expose cambelt. Lock the engine flywheel, fuel pump sprocket and cam sprocket. Loosen tensioner and remove belt. Fit new belt, set tension, remove locking tools then rotate engine twice by hand to check the timing holes align. If good, refit everything. If not, reset timing and check again.
Your service engine light keeps coming on and no matter what you do it wont stay off how can you fix this?
A check engine light comes on for a reason. The engine computer has detected something wrong somewhere in the engine management system and your car's computer needs to be scanned for fault codes to determine the source of the problem. If you have done all that then your cars check engine light needs to be reset, how this is done I am unsure. Get the engine serviced! The dealership can provide the service and cancel…
The check engine or service engine soon light comes on to alert you that there is or was a problem with the emissions system on your vehicle. If the light comes on steady and stays on, it means that there is a problem and you should have it checked out soon. If it comes on and flashes, it means you will cause damage if you continue driving.

I don't know about the 2000 year model directly but the 1996 is similar I am sure. To reset the "check engine" light, find the EFI fuse (probably under the hood in the fusebox on the driver's side) and with the engine off, remove it for one minute minimum. Replace the fuse and the "check engine" light should be reset.
