It is in the engine compartment. When you open the hatch it will be on the right hand side. It has a red cap and should have red fluid inside. Fill to the max mark with ATF Dextron.
From what I've read about changing the clutch master cylinder the resivor is behind the instrument cluster (spedo) ;) you can follow the hose from the master cylinder above the clutch pedal.
It's next to the Steering Wheel when you open the door.
I recently used STP in my 84 MB and it worked fine.
at the 15 side of the coil. 15 is ignition on voltage
Where do I add power steering fluid at for a 84 Park Avenue
Remove the cover of the speedo and you will see there. Good luck. The cover over the speedometer and tachometer removes by pulling from the back to the front, and lifting up. You will find the brake fluid reservoir in the middle on top of the master cylinder. This also serves the clutch slave unit if you have a manual transmission. In addition, you will find two screw-in switches in the sides of the master cylinder, these are pressure activated and control the brake lights (a common failure item, and cheap to replace. Be sure to use Dot 3 or Dot 4 brake fluid, but NEVER Dot 5. Bleed the brakes at least once every two years. Don't forget to Bleed the clutch slave too. Be sure to place an old towel or rag around the reservoir when filling, to avoid splashing of brake fluid on wires in area.
Yes. It's on the positive side of the coil.
It actually uses ATF in the power steering system. I believe Dextron IID was the spec for '84, but fortunately the newer Dexron formulations are backwards compatible.
check and adjust belts
depending on the motor, in all likeliness it is gong to be on the front of the engine to your right, just under the motors left valve cover.
There are 10.5 pints in 84 ounces.
7 fluid ounces times 12 equals 84 fluid ounces. 84 fluid ounces is equal to 10 and 1/2 cups.
