I have a 1987 Olds Delta 88 Brougham> It has a plastic drain plug that is on the drivers side of the radiator. The knob is broken and can be pulled from the radiator. Can you replace this part or does it require a new radiator?

There is a sensor in the belt buckle that wears out over time and also gets dirty. Try cleaning the buckle if that does not work replace the sensor. Does the drivers window not roll down and that is what makes you think it has no power? Take the door pannel off and have someone push the window button while you test to see if it gets power from a volt meter. If it does then the motor is bad.

YOU NEED BRAKE ROTORS FOR FRONT WHEEL DRIVE VECHICLE. THE 1987 OLDS DELTA 88 AND 1987 BUICK LESABRE FRONT WHEEL DRIVE SHOULD BE THE SAME.BUT GO TO AUTO PARTS STORES THEY CAN LOOK IT UP IF.BOTH HAD SAME TYPE FRONT WHEEL DRIVE SAME TRANSMISSION AND SAME WHEEL BASE AND DIAMTER EVERY THING SHOULD WORK OUT.

Hard to say on a older car such as this. If running well and healthly it should receive around 16 to 18 highway miles per gallon

1987 olds 88 6 cyl 3.8Liter fuel injected OHV is front wheel drive,1987 olds 88 Custom Cruiser 5.0L V8 4BBL is rear wheel drive.

there is a box under the hood on the right side near the windshield when facing the car, there are two plastic screws to undo to open the cover, on the inside of the cover are the placement of the fuse schematics

There are two possible things to check.The first being the ignition control module,and the other being the crankshaft position sensor.

On Type II coil packs, the coils can be replaced separately and the ignition wires are all on the same side of the coil pack.

With Type II Ignition

there should be a drain petcock on the bottom left or right of the radiator.
