Instructions needed to be Followed

  1. Drain the oil from the engine.
  2. Remove the oil pan.
  3. Remove the oil pump.
  4. Install the new oil pump.
  5. Install the new oil pan gasket.
  6. Fill the engine with oil.
  7. Bleed the cooling system.
  8. Start the engine and check for leaks.

Step 1: Drain the oil from the engine

To drain the oil from the engine, all you need to do is place a drain pan underneath the oil pan drain plug. After removing the drain cap with a wrench, let the oil flow into the pan. Change the drain plug and tighten it using the spanner you previously used after the oil has finished draining.

Step 2: Remove the oil pan

To remove the oil pan, use a spanner to loosen the oil pan bolts to remove the oil pan. You have to be careful not to drop the bolts into the oil pan. Once the bolts are loose, remove the oil pan, set it aside, and follow the next procedure.

Step 3: Remove the oil pump

To remove the oil pump:

  1. Use a spanner that matches the size to loosen the oil pump bolts.
  2. Be careful not to drop the bolts into the oil pan.
  3. Once the bolts are loose, remove the oil pump and set it aside.

Step 4: Install the new oil pump

To install the new oil pump, apply a thin coat of gasket sealant to the gasket surface of the oil pump. Then, carefully position the oil pump in place and secure it with the oil pump bolts. Tighten the bolts with a wrench.

Step 5: Install the new oil pan gasket

To install the new oil pan gasket;

  •  apply a thin coat of gasket sealant to the gasket surface of the oil pan. 
  • Carefully position the oil pan in place 
  •  and secure it with the oil pan bolts. 
  • Tighten the bolts with a spanner that matches its size.

Step 6: Fill the engine with oil

To fill the engine with oil:

  1. Remove the oil filler cap and pour oil into the filler neck.
  2. Consult your owner’s manual for the correct kind and amount of oil to use.
  3. Once the engine is filled with oil, replace the oil filler cap and tighten it.

Step 7: Bleed the cooling system.

To bleed the cooling system:

  1. Locate the bleeder valve on the top of the radiator.
  2. Open the bleeder valve and allow air to escape until a steady coolant stream flows out.
  3. Once the coolant flows freely, close the bleeder valve.

Step 8: Start the engine and subsequently look for leaks.

Start the engine and let it run for a few minutes. Check for leaks around the oil pan and oil pump. If you see any leaks, tighten the bolts or apply additional gasket sealant.

Once you have checked for leaks and are satisfied that there are none, you can turn off the engine and close the hood.

Here are some additional tips for replacing the oil pump on a Toyota Corolla:

  • Don’t let the oil pump bolts fall into the oil pan. Use a magnet to find the bolt if you drop it.
  • Apply a thin coat of gasket sealant to the gasket surfaces of the oil pump and oil pan before installing them. This will help to prevent leaks.
  • Tighten the oil pump and oil pan bolts to the specified torque. This will help ensure that the seals are correctly seated. 
  • After replacing the oil pump, be sure to start the engine and check for leaks. If you see any leaks, tighten the bolts or apply additional gasket sealant.

Replacing the oil pump on a Toyota Corolla is a relatively complex task, but it is possible to do it yourself with the right tools and knowledge. By following the steps in this guide, you can successfully replace the oil pump on your Toyota Corolla and avoid costly repairs at a dealership.

How to Know It’s Time To Change My Oil Pump?

4 Signs Of A Bad Oil Pump

The engine parts cannot be lubricated if the oil pump is malfunctioning. Low oil pressure or levels could potentially be the outcome, which could seriously harm the engine. 

To help you spot a faulty oil pump, here are some crucial warning signs: 

1. Reduced Oil Pressure

Usually, it’s difficult to open the oil pump’s pressure relief valve. However, if it accidentally opens, the oil pressure will decrease.

The first indication of an oil pump failure is typically low oil pressure. If your oil pump is bad, your engine’s oil won’t be adequately circulated. 

2. Higher Engine Temp.

The engine temperature may suddenly rise as a result of inadequate oil flow.

This occurs when your engine doesn’t get adequate oil flow, which prevents essential engine parts like the hydraulic lifters and valve-train from getting lubricated. Inadequate lubrication of these moving parts causes friction, which raises engine temperature. 

Therefore, pull over and let the engine cool down the next time you notice the temperature gauge climbing toward the danger zone. Consult a mechanic next to see if the old pump has to be replaced.

3. A loud engine

Another sign of an oil pump failure is a noisy engine.

Friction between various engine parts is caused by the absence of lubrication in moving parts such as the piston, hydraulic lifters, valve train, chain tensioner, or cam bearing. Consequently, a loud whining or whirring sound is produced.

It is essential to have your engine checked out right away by a mechanic if you hear these noises coming from your engine. 

4. The vehicle won’t start

In most recent cars, the oil pressure switch (also known as the oil transmitting unit) is directly connected to the ignition. Your engine parts are intended to be protected against harm by this feature.

The switch stops the engine from starting when it notices a malfunctioning oil pump. 

Your best course of action is to have a mechanic examine the issue because a no-start can result from a variety of factors, not only an oil pump that is failing.
