Assuming that it has a 4.3L engine, it would be the distributor.
Assuming this is a 4.3L engine, it is located under the hood, in back of the engine, on top, close to the distributor.
On a 4 cylinder (no distributor) engine it is located on the engine block, passenger side, directly over right engine mount, between the upper coil pack and oil pressure sensor. It is accessed through the wheel well. On a 6 cylinder with the distributor, it is located in the base of the distributor.
On the 4.3L V6 the distributor is located in the back of the engine, in the middle. Just follow the spark plug wires and they will lead you to it.
The distributor is located on the rear of the engine next to the firewall on a 2.0 4 cylinder.
Assuming this is the 4.3L engine, the distributor cap would be found in the back of the engine on top. All the spark plug wires lead to it.
Number one in the distributor cap is the one closest to the front of the engine on the passenger side of the car. The number one cylinder on the engine is also in the front of the engine on the passenger side.
On the six cylinder it is on the passenger side of the engine. On the eight cylinder it is behind the intake manifold on the back of the engine.
Assuming it has a 4.3 engine, the oil sending unit is located under the hood, in back of engine, drivers side, next to the distributor. It is difficult to see and get to. Removing the distributor makes it accessible.
If the engine is the 4.3, it is located under the hood, on top of engine, way in back, on the drivers side under the distributor.
If it has a V-8 engine, it is most likely at the back of the engine next to the distributor. IT screws directly into the engine block.
Yes it does. If it is a 4-Cylinder, it is on the transmission side of the engine cylinder head. If it is a V6, it is located on the transmission side of the front cylinder head.
