Can you change the oil pump without pulling the motor on a c10?

It depends on the year and engine of the C10.

In some cases, it may be possible to change the oil pump without pulling the motor. However, it can be a difficult and time-consuming task as it involves removing the oil pan and possibly the timing cover.

If the engine has sufficient clearance and there is enough space to work around the pump, it may be possible to replace it without removing the motor.

It’s important to note that if the oil pump has failed, there may be serious underlying issues with the engine, such as damage to the bearings or worn-out seals. These issues should be addressed in addition to replacing the oil pump to ensure the longevity and reliability of the engine.

It is recommended to consult a certified mechanic or service manual for specific guidance on this procedure.
