How To Install Mechanical Oil Pressure Gauge


A mechanical oil pressure gauge is a valuable tool for monitoring the health and performance of your vehicle’s engine. Installing one can provide you with real-time oil pressure readings, allowing you to detect any potential issues early on. In this article, we will walk you through the step-by-step process of installing a mechanical oil pressure gauge in your vehicle.

Tools and Materials Required

Before you begin the installation process, make sure you have the following tools and materials:

  • Mechanical oil pressure gauge
  • Oil pressure sender unit
  • Wrench set
  • Socket set
  • Drill and drill bits
  • Electrical wire
  • Wire connectors
  • Electrical tape
  • Thread sealant

Step 1: Choose a Suitable Location

The first step in the installation process is to choose a suitable location for your oil pressure gauge. You want to select a spot that is easily visible from the driver’s seat but does not obstruct your view of the road. A common location is the A-pillar or dashboard. Make sure there is enough space to mount the gauge without interfering with any other components.

Step 2: Prepare the Mounting Area

Once you have chosen a suitable location, you need to prepare the mounting area. Use a drill and the appropriate drill bit to create a hole for the gauge. Make sure the hole is slightly smaller than the diameter of the gauge so that it fits snugly. Clean any debris or sharp edges around the hole to ensure a secure fit.

Step 3: Install the Gauge

Now it’s time to install the oil pressure gauge. Start by inserting the gauge into the hole you drilled in the previous step. Make sure it fits securely. If the gauge comes with a mounting bracket, use a wrench or socket set to securely fasten it. If not, you may need to use a custom mounting solution such as adhesive tape or brackets.

Step 4: Install the Oil Pressure Sender Unit

The oil pressure sender unit is responsible for reading the oil pressure and sending the signal to the gauge. Locate the original oil pressure sender unit in your vehicle’s engine. It is usually located near the oil filter or on the side of the engine block. Use a wrench or socket set to remove the original sender unit.

Step 5: Connect the Oil Pressure Gauge to the Sender Unit

Once the original sender unit is removed, attach the new oil pressure sender unit that came with your gauge. Use a suitable wrench to tighten it securely. Next, connect one end of an electrical wire to the oil pressure sender unit and the other end to the back of the oil pressure gauge. Use wire connectors and electrical tape to ensure a secure connection.

Step 6: Secure the Wires

After connecting the wires, secure them away from any moving parts or hot surfaces. Use zip ties or wire clips to hold the wires in place. Make sure they are not pinched or exposed to excessive heat.

Step 7: Check for Leaks

Before you start your engine, apply thread sealant to the threads of the oil pressure sender unit to prevent any oil leaks. Tighten it securely but be careful not to overtighten. Once everything is in place, visually inspect for any signs of oil leakage.

Step 8: Test the Gauge

Start your engine and let it warm up. Observe the oil pressure gauge to ensure that it is reading accurately. The gauge should display the normal operating oil pressure for your vehicle. If the gauge does not move or displays an incorrect reading, double-check all connections and consult the gauge’s instruction manual.

Step 9: Reassemble and Clean Up

If the oil pressure gauge is working properly, reassemble any components you removed during the installation process. This may include reattaching the dashboard, A-pillar cover, or any other parts you had to remove to access the oil pressure sender unit. Clean up the workspace, removing any leftover debris or tools.


Installing a mechanical oil pressure gauge in your vehicle is a relatively straightforward process. By following these step-by-step instructions, you can have a reliable tool to monitor your engine’s oil pressure. Remember to be cautious during the installation process and always consult your vehicle’s manual or a professional if you encounter any difficulties or have any questions.
