How to Use an Oil Filter Wrench

Engine oil is one of the most important car fluids. Keeping it at optimal levels and changing it regularly ensures that your car’s engine runs smoothly. Occasionally, you’ll also have to change the oil filter as well, which isn’t so hard to do, even though it can seem that way at first. 

Sometimes, filters can become a bit stuck over time due to heat, residual oil, and pressure. That’s when you should use an oil filter wrench, because removing the filter by hand might be impossible.

What You Need Before You Start

To use an oil filter wrench, you’ll also need some other things, including safety equipment, the correct oil filter wrench type, and ensure that your car is parked on a flat surface. 

  • Safety Equipment (gloves and eye protection): Since there will be a lot of old oil pouring out, you’ll need a pan or similar vessel to catch all that oil. Don’t forget to get some old rags or paper towels, as you’ll need them to clean up a bit.  
  • Check the Correct Oil Filter Wrench Type: You can choose between options such as strap wrenches, cap-style wrenches, pliers-style wrenches, and chain wrenches. Each option has its specific applications, so make sure to research them before making your choice.
  • Pack Your Car on a Flat Surface: Your car should be parked on a flat and even surface. The engine should be warm but not hot. Warm oil will pour out more easily, but if the engine is too hot, the oil will be hot as well, which could lead to serious burns.

How to Use an Oil Filter Wrench: Step-by-Step

Now that you have gathered everything, you are ready to use your oil filter wrench. Follow these steps:

  1. Find the oil filter. Most oil filters are cylindrical and mounted either vertically or horizontally on the engine block.
  2. Once you have found the filter, position the pan right below so that it can catch all the oil that will soon start to come out.
  3. Attach the wrench to the filter and ensure that it fits snugly. If you are using a cap-style wrench, align it with the end of the filter and attach it to a ratchet. For strap or chain wrenches, wrap the strap or chain around the filter and ensure it grips firmly.
  4. Turn the wrench counterclockwise to loosen the filter. Apply steady pressure instead of jerking the tool. 
  5. Once the filter breaks free, you can continue unscrewing it by hand. 
  6. As the filter comes off, tilt it slightly upward to reduce spills, then lower it into the drain pan.
  7. Clean the mounting surface with a rag to remove any leftover debris that could prevent a proper seal once you install a new filter.
  8. When installing the new filter, lightly coat the rubber gasket with fresh oil and tighten it by hand.

Tips for Using Different Types of Oil Filter Wrenches 

We already mentioned that there are several types of oil filter wrenches, and we have briefly explained how to use them. However, if you need more information on how to use a cap-style vs a pliers-style wrench, here are some useful things to know:

1. Strap Wrenches

  • Strap oil filter wrenches work on a wide range of filter sizes, but the strap must be wrapped so it tightens as you turn counterclockwise.
  • Keep the strap clean and dry. Also, make sure there is enough clearance around the filter for proper grip.

2. Cap–Style Wrenches

  • Cap-style oil filter wrenches provide a snug, secure fit. They are ideal for filters that are difficult to reach.
  • However, before using them, always verify the cap matches the filter size, and then use a ratchet to apply steady, controlled pressure.

3. Pliers–Style Wrenches

  • Pliers-style oil filter wrenches offer a strong gripping force. They are the best choice for stubborn filters.
  • Position the wrench jaws near the base of the filter and apply steady pressure to avoid crushing or tearing the filter body.

4. Chain Wrenches

  • Chain oil filter wrenches are perfect for working with extremely tight filters, especially if they are made of metal.
  • Align the chain evenly around the filter and apply a slow but controlled force to prevent slipping or damage.

Common Mistakes to Avoid When Using an Oil Filter Wrench

  • Using the wrong type/ size of wrench: One of the most common mistakes that people make when using an oil filter wrench is using the wrong type or size. As a result, they can’t get a proper grip on the filter and can’t remove it. 
  • Over-tightening with the wrench: Another common mistake is over-tightening with a wrench when installing a new filter, as it can cause leaks or make the next oil change more difficult.
  • Many people also forget to check whether the old gasket came off with the old filter. Leaving it behind can cause serious leaks when the new filter is installed. 
  • Using too much force: Another mistake is applying too much force too quickly. Sudden movements increase the risk of injury and can strip threads or tear the filter.

What if the Oil Filter is Really Stuck? 

If the filter isn’t moving no matter what you do, try to reposition the wrench and start over. Sometimes, it is just an unfortunate angle that prevents you from getting a good grip. If that doesn’t solve your issue, try a different type of filter wrench. If you have it, try a pliers-style wrench. 

Some people use extreme measures, such as driving a screwdriver through the filter or tapping the filter with a rubber mallet to break the seal. 

However, keep in mind that doing this could lead to more mess and even some damage, so we don’t recommend it. Instead, take your car to the mechanic and let the professional deal with it.
