why does my Ford F-150 12th Generation (2009-2014) have low oil pressure

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues during repairs.

2. Change Engine Oil and Filter

1. Drain Old Oil

   • Place a drain pan under the oil pan.
   • Remove the oil drain plug using a socket wrench and allow oil to fully drain.
   • Reinstall the drain plug and torque to manufacturer specifications (typically around 20-25 ft-lbs).

2. Replace Oil Filter

   • Locate the oil filter and use an oil filter wrench to remove it.
   • Apply a thin layer of fresh oil on the rubber gasket of the new filter.
   • Install the new oil filter, tightening it by hand until snug (do not over-tighten).

3. Add New Oil

   • Remove the oil filler cap and pour in the manufacturer-recommended oil (typically 5W-20 or 5W-30).
   • Replace the oil filler cap securely.

3. Inspect Oil Pump

1. Remove Oil Pan

   • Drain oil if not already done.
   • Unbolt the oil pan from the engine block and carefully remove it.
   • Inspect the oil pump for visible damage or wear.

2. Replace Oil Pump (if necessary)

   • Remove the bolts securing the oil pump.
   • Install a new oil pump, ensuring to align it properly.
   • Torque bolts to manufacturer specifications.

4. Replace Oil Pressure Sending Unit

1. Locate Sending Unit

   • Identify the oil pressure sending unit near the oil filter or engine block.

2. Remove and Replace

   • Disconnect the electrical connector.
   • Use a socket to remove the sending unit.
   • Install the new sending unit, tightening it securely.
