Oldsmobile Cutlass Supreme - Recent Questions, Troubleshooting & Support

there are timing marks or notches on the head and a timing (dot) on the cam gear, and also on the crank gear and block.make shure these are all allined before tightning the belt tensioners.

What size is the fuel pump stud bolt

I answered this in great detail earlier. The answer is no. The inside is clean and doesn't need flushing. Some refrigeration gases are wonderful solvents and based on Carbon Tetrachloride! You only replace an evaporator if it fails. It is always a big job and usually the dash needs to come off. And I asked you not to use abbreviations and use long form. Question edited again and put in the make year model category.

Question edited for clarity, long form always, full names. Question moved to model category. Externally or Internally? Externally, blow with compressed air. Internally, why? It is full of refrigerant in gas and liquid form, with a little lubricating oil. Not sure what you think you can flush it with, but if you tried any 'wet' way, you will end up with moisture problems that the air dryer cartridge can't handle. Some type of solvent spirit and compressed air, maybe. If you do empty the system, this is what it involves, but again why? https://www.fixya.com/cars/r29878326-recharging_vehicle_air_conditioner ..

which motor 3.1 or 3.4 give me email address send diagram

Try having the ignition module checked. The ignition module is located underneath of the coil packs. Usually Auto Zone or Advance Auto Parts can test them. Another possibility is low fuel pressure. There is a schrader valve on the fuel inlet line that you can hook up a fuel pressure tester to. The pressure should be around 38 PSI.

My 3.4 liter 91 Cutlass Supreme has similar problem when warm the engine misses (car jerks). But its fine at idle and without any accelerator pressure. The SERVICE ENGINE light also comes on intermittantly. I am going to test the ignition coils.

You can go to a nearby parts store and purchase a Haynes automotive reference guide and it contains all the different diagrams that would need. On the front of the book it would say 1990-94 lumina cutlass etc.

broken --as in damaged or just not unlocking if the latter can have a service slim doors ---as to removing upper rear seat to enter compartment no easy but can be done need to release the support bar from the retaining clips by pushing down

If not reachable from underneath the engine tips forward to change they make a holding tool. Loosen the dog bone engine mounts and lean on the car you'll see the engine move pull it forward with a bar then find something to hold it there. I hope this helps. Take Care.

Sounds like you have either a bad fan connection or you need to replace the fan motor itself.

Check all the wiring leading to the fan, and the fan controller. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Hello! Have you recently disconnected the battery? If so the radio is locked. If you do not have the unlocking code, take the vehicle to an authorized Oldsmobile dealer, give them the VIN# plus proof of ownership and they will give you the code...

THEY WEAR OUT JUST LIKE EVERY THING DOES

I REPLACED THE BATTERY, STARTER CYLINOID ETC. FINALLY WE TOOK OUT THE SECURITY SYSTEM FROM UNDER THE DASH. STARTS EVERY SINSE

I'm afraid I can't send you a diagram but I see nobody else has sent you one either. So here goes. Your odd numbered cylinders, 1-3-5-7 are on the driver's side front to back. Your even numbered cylinders, 2-4-6-8 are on the pasenger side front to back.
Your distributor cap should have 4 hold down screws placed at 2 o'clock, 5 o'clock, 8 o'clock and 11 o'clock. Your number 1 cylinder is the first plug tower toward the firewall (or behind) the 2 o'clock hold down screw.The distributor runs counter clockwise or backwards and the firing order is 1-8-4-3-6-5-7-2.
Your timing depends on which model you have. All models except Tornado are timed at 16 degrees before TDC. The Tornado is timed at 12 degrees. The timing also is set with the engine running at 1100 RPM not the traditional idle speed. Hope this helps.
