The firing order for a 1986 Oldsmobile Cutlass Ciera 2.8 V6 is 1, 2, 3, 4, 5, 6. The number one cylinder is on the front left as you face the engine compartment.
On a 1986 Cutlass Ciera, the motor mounts are located on either side of the engine block, securing the engine to the frame of the vehicle. Typically, there are two main mounts: one on the driver's side and one on the passenger's side. Additionally, there may be a rear mount supporting the engine at the back. These mounts help absorb vibrations and maintain engine alignment.
On the turn indicator. Pull the turn indicator toward you until you hear it "click", about 1/4", then release.
In a 1986 Cutlass Ciera, the cooling fan is typically controlled by a temperature sensor located in the engine coolant passage or near the thermostat housing. This sensor monitors the engine temperature and signals the fan to activate when the temperature exceeds a certain threshold. Additionally, there may be a relay in the electrical system that controls the power to the fan based on the sensor's input.

To install a water pump on a 1986 Oldsmobile Cutlass Ciera, first, disconnect the battery and drain the coolant. Remove the serpentine belt, then detach any components that obstruct access to the water pump, such as the alternator or power steering pump. Unscrew the old water pump from the engine block, clean the mounting surface, and install the new pump with a fresh gasket. Finally, reassemble everything, refill the coolant, and reconnect the battery.
