1994 Oldsmobile Cutlass Supreme - Answered Questions & Fixed issues

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.

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 ..

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

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

Usually there is a problem with the IAC (idle air control motor) or the TPS (throttle position sensor).

I would check to see if you are getting power to the small wire on the starter solenoid when you turn the key to the starting position. If so, you may have a bad starter or solenoid.

youve got a bad mastercylinder

Sounds like you are not getting enough current from the battery to the starter. If your battery is fully charged, make sure the the battery cables are tight and corrosion free (baking soda & vinegar will clean the terminals, rinsed with clear water afterwards) and make surw connections on the starter are tight. There is also a starter relay in the circuit that could be bad. You could use booster cables to connect battery direct to the starter to see if it turns the engine over, but make sure polarity is correct. Put one end of the booster cable on the the plus side of the battery, then take the other end and touch the plus (+) side of the starter. If engine turns over (it will not start) then problem is either cables, connections, or starter relay. If it doesn't turn over, I suspect the battery itself or the starter.

Also adjust the passenger wiper, similar to the way you adjusted the driver side.

Number 4 at the top is rod for release. I couldn't get everything in one picture. It appears to me, you need to remove door panel and then check everything.

007 Idle Speed Problems Scan Data for Idle Hooking up a scan tool that can view engine sensor data is the way to find these type problems .

These are called belt weather or sealing strips. I think the parts you are looking for are 12503936 and 37, but they are discontinued parts. Good luck finding them - try auto wreckers (online search).

Has the ECM been scanned? Read the live readings from the sensors to see if u have any direction of the problem. Maybe even diagnostic codes. Coolant sensors are known for this issue too. Take an emissions reading & read the emissions. Good Luck

Go to any auto zone or parts store and you can borrow a puller to remove the harmonic balancer. Try to get a repair manual to assist you in the removal procedure.

3 on each side of the block(under to car to see them) and 2 between the engine and transmission.

It's mounted in the right rear notch of the air intake by the fire wall or on the fire wall in that general location. with a vacuum line attached. That is standing in front of the car at the rear top edge of the manifold. Look it up on parts geek you can look at the enlarged picture to see what yo are looking for.

hi.you elimanated all the firing problems i would say try the feul side it can be a dirty feul filter or a faulty injector it can be injector wires or air mass meter or a leak in the intake manifold I will say start with the feul filter.hope this helps
