The water pump on a 1985 Delta 88 Royal is in the engine compartment. It is located next to the timing belt.

The 1975 Oldsmobile Delta 88 typically accommodates 6x9-inch speakers in the rear deck and 5x7-inch or 6.5-inch speakers in the front doors. However, the specific size may vary based on the vehicle's original audio system configuration. It's always a good idea to measure the existing speaker openings to ensure a proper fit for replacement speakers.
Depends on the engine
The 1985 Oldsmobile Delta 88 typically came with a ring gear size of 8.5 inches for the rear axle. This size is associated with the GM 10-bolt rear differential commonly found in many GM vehicles of that era. However, it's important to verify the specific axle type and gearing ratio for your particular vehicle, as variations may exist.

If a person loses the keys to a trunk of a 1985 Delta 88, the best way to get into the trunk is to remove the back part of the back seat. Some models came with an escape hatch in the trunk where a person could open part of the back seat to access the trunk. The back of the back seat can be removed by first removing the area behind the back seat where the speakers are.
You gotta use tools.
I'm trying to find out how to hook up the vacuum hoses to the carb in a 85 delta 88. I need to know how they go.
