How to Change Your Chevy HHR's Oil Filter

Getting Started With Your Oil Filter Change

Changing your Chevy HHR's oil filter is a maintenance task you can do at home with basic tools and some preparation. This guide walks you through each step so you understand what's involved in this routine maintenance job. Many HHR owners find this is a straightforward project that saves time and money compared to taking the vehicle to a shop.

Regular oil filter changes are an important part of keeping your HHR running smoothly. The oil filter removes dirt and debris from your engine oil, and over time it becomes clogged and less effective. Learning how to do this yourself means you can stay on top of your vehicle's maintenance schedule whenever it's convenient for you.

What You'll Need

Before you begin, gather these items so everything is within reach:

• A new oil filter (the right size for your HHR model year)
• An oil filter wrench
• A drain pan or container
• Jack and jack stands (or ramps)
• A socket set and wrench
• Safety glasses
• Work gloves
• Clean rags or paper towels

Having everything ready before you start makes the job go faster and smoother. You can find oil filter wrenches at any auto parts store, and they're inexpensive. Make sure you have the correct filter size for your specific HHR year—check your owner's manual or ask at an auto parts store if you're unsure.

Step 1: Prepare Your Vehicle

Park your HHR on a level, flat surface. Engage the parking brake firmly. If you need to reach underneath the vehicle, use a jack and jack stands to lift it safely. Never rely only on a jack—always use stands as a backup for your safety. Place the stands on solid frame points, not on plastic trim or other weak areas.

Let the engine cool for a few minutes if you've been driving recently, but a warm engine is actually better for this job because the oil flows more easily. Cold, thick oil takes longer to drain out. Wait until the engine is warm but cool enough to touch safely—you don't want to burn yourself on hot metal.

Step 2: Locate the Oil Filter

On most HHR models, the oil filter sits on the side of the engine block. The exact location can vary depending on your model year, so check your owner's manual if you're not certain where yours is positioned. You may need to remove a plastic splash guard or undercarriage panel beneath the engine to reach the filter easily.

Take a moment to look around the filter area and understand how it's positioned. This helps you figure out the best angle to approach it with your wrench and where to position your drain pan to catch the oil that will spill out.

Step 3: Remove the Old Filter

Position your drain pan directly underneath the filter to catch the oil. Use your oil filter wrench to grip the filter firmly and turn it counterclockwise until it comes loose. Once it's loose enough to move by hand, finish unscrewing it carefully. Be cautious because there will be oil inside the filter, and it may still be warm from the engine.

Once the filter is completely free, let it drain into the pan for a minute or two. This allows more of the old oil to drip out rather than spilling onto your engine or floor. After it stops dripping, you can set the old filter aside in a safe place where it won't tip over.

Step 4: Clean the Filter Housing

Use a clean rag to wipe the filter housing area where the old filter was attached. This is the threaded metal surface on the engine where the new filter will screw on. Look carefully for an old rubber gasket or seal that might still be stuck on the housing—this must be removed or the new filter won't seal properly.

Remove any debris, old oil residue, or dirt from the housing. A clean surface ensures that your new filter will seat correctly and won't leak. Take your time with this step, as it's one of the most important parts of the job.

Step 5: Install the New Filter

Take your new filter and apply a thin layer of fresh oil to the rubber gasket on the top of the filter. This rubber ring helps create a watertight seal when the filter is screwed on. The oil helps it compress evenly and prevents leaks. You only need a light coating—not a thick layer.

Screw the new filter onto the housing by hand until you feel the rubber gasket make contact with the metal surface. At that point, turn the filter an additional three-quarter turn to tighten it. Don't over-tighten it—hand-tight plus three-quarter turn is the right amount. Over-tightening can damage the filter or make it hard to remove next time.

Step 6: Check Your Work

Start your engine and let it run for a few seconds. This allows oil to flow through the new filter and fill it up. Watch the area around the new filter carefully for any leaks or drips. If you see oil dripping, turn off the engine and allow it to cool slightly, then tighten the filter a bit more with your wrench.

Turn off the engine and wait about a minute for the oil to settle. Then check your oil level using the dipstick. Pull the dipstick out, wipe it clean with a rag, reinsert it fully, and pull it out again to see the level. Add fresh oil if needed to reach the proper level marked on the dipstick. Your owner's manual tells you what type of oil your HHR needs.

Step 7: Dispose of the Old Filter

Take your old filter to an auto parts store, recycling center, or local service station. Many of these places accept used oil filters for free or for a small fee. Some stores will even take them if you purchase a new filter from them. Never throw an old filter in the regular trash because the oil inside is an environmental hazard.

You should also dispose of the old oil properly. If you drained oil during this job, take it to the same places that accept filters. Never pour old oil down a drain or into the ground.

Key Takeaways

Changing your HHR's oil filter involves removing the old filter, cleaning the housing, and installing a new filter with proper sealing. The entire process usually takes 15 to 30 minutes once you've gathered your tools and prepared your workspace. With practice, you may find it takes even less time.

This is a routine maintenance task that many HHR owners handle themselves. If you run into problems, feel unsure about any step, or prefer to have someone else do the work, a mechanic at a service shop can handle this job for you quickly and professionally.

Frequently Asked Questions

How often should I change my HHR's oil filter?

Most manufacturers recommend changing your oil filter every time you change your engine oil. Depending on your HHR model year and driving habits, this is typically every 3,000 to 10,000 miles. Check your owner's manual for the specific interval recommended for your vehicle. Some newer models can go longer between changes, while older ones may need more frequent service.

What should I do if oil leaks from the new filter?

A small amount of oil may drip immediately after installation, but it should stop quickly. If oil continues to leak, turn off the engine and let it cool. Check that the rubber gasket wasn't stuck to the old housing—if it is, remove it. Then ensure the new filter is screwed on correctly. The gasket should be touching the housing, and the filter should be turned an additional three-quarter turn. If leaking continues after you've checked these things, the filter may be defective or the wrong size for your vehicle.

Can I reuse my old oil filter?

No, oil filters should never be reused. Once a filter has been used, it becomes clogged with dirt and debris that cannot be cleaned out. A clogged filter cannot protect your engine effectively. Always install a fresh, new filter each time you perform this maintenance. Using a new filter ensures your engine oil stays clean and your engine runs properly.
