8 Simple Steps on How to Check Oil Pressure Without Gauge

When you’re going through this, trust me it’s really easy and beginner friendly. So, read the steps properly, don’t have any confusion and I believe you will be able to pull it off.

Step-1: Learning how the oil pressure works

First things first, we gotta understand how oil pressure works. 

So, the oil pump in every vehicle does the job. When your engine is running, the oil pump sends oil to all the important parts to keep ’em greased up and prevent overheating. Proper lubrication and cooling is done here.

Now you usually have a gauge or a little light on your car’s dashboard. What does that do? It helps to measure the oil pressure of your favorite vehicle. 

If that pressure gets too low, it’s bad news for your engine. It can mess things up and cause some serious damage. 

So, it’s crucial to keep an eye on that oil pressure.

Step-2: Watch Out for Warning Signs

Let’s move on to the second step. 

Have a glance at your oil pressure gauge. If it’s giving you the lowdown, then you’ve got yourself an oil pressure issue. Yes, it is unfortunate and I hope you don’t find it like that.

Also, that’s just not it. Try to check the oil pressure light on your dashboard too.Why?

 If it’s flashing or showing lights, it’s a clear sign of oil issues. What to do? 

Feed it more. Give your car some more oil.

Wondering what can be the reason? Well, this problem can happen for a few reasons. 

  • It could be because your oil level is running empty
  • Or your oil filter is all clogged up like a traffic jam

So, be on the lookout for these warning signs, and if you spot them, it’s time to take action.

Step 3: Time to Have a Look at the Oil-Level

Now, when it comes to low oil pressure, the first thing you gotta do is check your car’s oil level. 

It puts extra strain on the oil pump when the level is low. This is when the oil pump starts to cause low oil pressure.

What to do? 

Remove that dipstick and give it a nice clean up. Clean it up as much as you can.

Then, slide it back into the engine and pull it out again. Take a good look between those two marks on the dipstick, that’s where the magic happens.

Can you see the oil level in the correct spot? Hope so. 

But, If you don’t see the oil level in the right spot, it’s time to pour in some more oil until you hit the right level. 

Step 4: Monitor the Oil Pressure Gauge

If your vehicle is equipped with an oil pressure gauge, you’re in luck. 

This helpful gadget allows you to directly assess the oil pressure situation. 

Here’s what you need to do. Start the engine and let it idle for a few minutes. Why? Just allow it to settle into its rhythm. 

Then, divert your attention to the gauge and take note of the reading it displays.

Now, it’s crucial to keep in mind that oil pressure can exhibit fluctuations while the engine is in operation. 

Therefore, for a more precise evaluation, try to check the gauge multiple times. 

By doing this, you can ensure an accurate reading and better understand if the oil pressure is lower than the normal. 

Step 5: Keep an eye on the Oil Pressure Light

I have some good news if your vehicle is equipped with an oil pressure light on the dashboard. You’ve got yourself an extra tool to check the oil pressure. 

So at first, start the engine and allow it to idle for a few minutes. Now, it’s time to keep your eye on that pressure light and see if it decides to turn on.

When that light turns on, it’s an unmistakable sign that there’s an oil pressure problem in your car. 

However, it’s crucial to bear in mind that sometimes the light can also come on due to a glitch in the sensor responsible for detecting the oil pressure. 

So, while the light serves as a helpful warning, it’s wise to consider further investigation to determine the exact cause of the issue.

Step 6: Can you find Warning Signals

Now, if you’re not quite certain about the state of your car’s oil pressure, do not worry! I will have some other clear signs you can check out. 

The first thing is to keep your ears open for any unusual noises coming from the engine. I got to experience this couple of times and trust me, it does not feel good to hear that kind of sound. Always, always brings some kind of bad news.

These peculiar sounds could definitely be a red flag that the oil pressure is running low.

On top of that, pay attention if your car starts vibrating more than usual. This abnormal behavior could also serve as an indicator of low oil pressure.

 If you happen to notice any of these warning signals, it’s crucial to take immediate action. So, try to get it checked by a mechanic. 

Remember, timely intervention can help prevent any potential damage and ensure the smooth operation of your vehicle.

Step 7: Driving the Car Carefully

Always keep in mind, Safety first!

If you are still not sure about the oil pressure. If it’s alright or not, then it’s time to take it out for a ride. 

But hey, not so fast. Keep driving it carefully until you can address the issue.

Also don’t forget to take frequent breaks during your journey. Give yourself and your trusty ride a chance to cool down and prevent any overheating issues from rising up

Remember, it’s better to play it safe and be a bit more cautious until you can solve the oil pressure matter properly. 

Step 8: Seek Professional Inspection

Last but not the least, you can always take help from a mechanic.

If you take your car to a good mechanic they know how to put your worries to rest.

So take your car to a reputable mechanic and let them work their magic. They’ll dig deep into the issue, determine if there’s a problem with the oil pressure, and provide you with expert advice on the next steps to take.

Yes, I know what you are thinking. It might take a dig into your pocket. But still, their experience and expertise will guide you towards the best course of action.

How Can You Use the Homemade Oil Pressure Tester : 9 Easy Steps

There are a couple of ways to check the oil pressure without the gauge. Do you know the most common way?

It’s by using a homemade oil pressure tester. But how can you use the homemade oil pressure tester? Well, in this part, I will share 9 easy steps to use the Oil Pressure Test Kit tool.

1. You will need to start your engine. But before that you need to do some things. Make sure it’s cool down, apply the handbrake, turn the wheels, and put the transmission in park.

2. Alright, the next step is to locate the oil pressure or temperature sender. You can usually find it on the engine block, often near the sump.

3. Time to take out that switch!

Just make sure you’ve got an oil drip tray handy to catch any spills. The Oil Pressure Test Kit comes with different adapters to fit different thread patterns.

4. The next thing you need to do is track down the right match for your engine. Then you must attach it to the block where the old oil pressure center was removed.

5. Now the oil tester needs to be connected with the adapter. Remember to give your oil level a quick check before firing up the car.

6. You need to consult your service manual. Why? To determine the recommended RPM for performing the test. And allow the engine to reach its operating temperature accordingly.

7. The next step is a bit critical. 

Maintain the engine at the specified RPM while you take the reading. If the reading is low, it could indicate a worn oil pump or a clogged oil filter that might require replacement with a thicker oil viscosity. 

Conversely, a high reading might suggest a faulty pressure relief valve that needs attention ASAP.

8. After you’ve obtained the reading, it’s important to shut down the engine. Wait, the job isn’t done yet. Allow it to cool down before removing the oil pressure tool.

9. Lastly, once the oil top-up and any necessary work are completed, make sure to reinstall the test gauge and oil pressure sensor.
