On a 1990 Chevy Lumina, the oil pump is located inside the engine's oil pan, which is at the bottom of the engine. To access the oil pump, you'll typically need to remove the oil pan and the pickup tube. The oil pump is driven by the crankshaft and is responsible for circulating oil throughout the engine to ensure proper lubrication.
The oil pressure switch on a 90 Chevy Camaro is located on the bottom of the engine near the oil filter. It constantly monitors the function and output of the oil pump.
The '90 through '96 Luminas weighed approximately 3,600 lbs.
there is a second oil pressure switch that shuts off the fuel pump if theres not enough oil pressure
3.4 litre cylinder head torque is 37 ft lbs +90 degrees
