2.5 pound or at least that's what my 1990 Chevrolet k1500 says it takes you might can look on the sticker on top of the silverish cylinder at the top left under the hood.
It only has one. It is located in the exaust manifold in front of the engine. Four cylinder that is. If by chance you have a V6, then it would have two, both located in the exhaust maifolds, on the front, and back of the engine.
One for each cylinder, six in a six cylinder, four in a four cylinder.
