The oil drain plug allows you to remove old engine oil from the oil pan so fresh oil can be added, ensuring proper lubrication and engine longevity.
This guide explains where to find the oil drain plug, how it varies by vehicle type, and tips for safely accessing it.
Where Is the Oil Drain Plug Located
The oil drain plug is located at the lowest point of your vehicle’s engine oil pan, typically underneath the front of the engine. It is a hex-head bolt that allows old engine oil to be drained during an oil change.
While most cars, SUVs, and trucks have the drain plug directly on the oil pan, its exact position can vary depending on the vehicle’s drivetrain, engine design, or presence of protective splash shields.
Motorcycles and heavy-duty trucks may have different or multiple drain plugs, so it’s always best to consult the owner’s manual to identify the correct location.
| Vehicle Type | Typical Drain Plug Location | Notes / Tips |
|---|---|---|
| Passenger Cars (Sedans, Hatchbacks, Coupes) | Underneath the engine, on the lowest part of the oil pan | May require lifting the car; often at the rear of the oil pan |
| SUVs and Pickup Trucks | Bottom of the oil pan beneath the engine | Higher ground clearance; sometimes protected by skid plates or splash shields |
| Front-Wheel Drive Vehicles | Rear portion of the oil pan | Positioned to avoid drivetrain components |
| Rear-Wheel Drive Vehicles | Center or side of the oil pan | Check for access around the crossmember |
| All-Wheel Drive Vehicles | Angled on the oil pan for clearance | Sometimes partially hidden behind protective covers |
| Motorcycles | Crankcase bottom; some models have separate plugs for engine and transmission oil | Always refer to the owner’s manual; some require removing side covers |
| Heavy-Duty Trucks & Diesel Engines | Large oil pan under engine block, sometimes dual plugs | Dual plugs allow faster oil draining; protective shields may cover the pan |
| Hybrid & Electric Vehicles (with combustion engines) | Oil pan drain plug beneath the engine, often behind protective shields | Shields may need removal; EV-only models do not have engine oil |

Key characteristics:
- Usually made of steel or aluminum
- Hex-head bolt design
- Sealed with a crush washer or gasket
- Positioned at the bottom of the oil pan for complete drainage
Where Is the Oil Drain Plug Located on Most Vehicles?
Standard Location
On most cars, trucks, and SUVs, the oil drain plug is located:
Under the engine, attached to the oil pan at the lowest point.
How to identify it:

Visual Identification Tips
Look for:
- A bolt facing downward
- Positioned on the lowest part of the oil pan
- Often near the rear of the engine
- Surrounded by oily residue (common sign)
Avoid confusing it with:
- Transmission drain plugs
- Differential plugs
- Coolant drain bolts
Safety Tips When Accessing the Drain Plug
- Always use jack stands — never rely solely on a jack.
- Wear gloves to avoid burns from hot oil.
- Allow the engine to cool before starting.
- Use the correct socket or wrench size to prevent stripping.
Why the Location Matters
Knowing where the drain plug is located helps you:
- Perform oil changes safely
- Prevent draining the wrong fluid
- Avoid damage to engine components
- Save time and maintenance costs
Common Mistakes to Avoid
1. Removing the wrong plug
Some people accidentally remove the transmission drain plug.
Tip: Engine oil pans are directly under the engine, while transmission pans sit further back.
2. Stripping the plug
Using the wrong tool can damage the bolt.
Tip: Always use the correct socket size.
3. Overlooking splash shields
Many modern cars hide the oil pan.
Tip: Inspect for protective panels before searching further.
FAQs
Where to locate the oil drain plug?
The oil drain plug is located at the lowest point of the engine oil pan, typically underneath the front of the vehicle. It is a hex-head bolt that allows engine oil to drain during maintenance. The exact location may vary depending on the vehicle type, drivetrain, or protective shields covering the oil pan. Always consult your owner’s manual for the precise location.
How do I drain the oil from my car?
To drain oil, park your car on level ground and let the engine cool. Lift the vehicle safely using ramps or a jack with jack stands. Place an oil catch pan under the oil pan, remove the drain plug using the correct wrench or socket, and allow the oil to completely drain. Afterward, replace the drain plug and tighten to the manufacturer’s torque specification, then refill the engine with fresh oil.
How to get an oil drain plug off?
Use the correct size wrench or socket to turn the oil drain plug counterclockwise. If the plug is stuck due to corrosion or overtightening, a breaker bar or penetrating oil can help loosen it. Always avoid stripping the bolt by using the proper tool and applying steady, controlled force.
How much does it cost to fix an oil plug leak?
Repairing a leaking oil drain plug typically costs between $20 and $100 depending on the cause. If the leak is due to a worn washer or gasket, replacement is inexpensive. If the oil pan or threads are damaged, the cost may be higher due to part replacement and labor.
Can I drain my engine oil myself?
Yes, draining engine oil is a common DIY maintenance task if you have the proper tools, safety equipment, and knowledge. Ensure the car is on a level surface, the engine is cool, and you have a suitable catch pan. Always follow manufacturer recommendations for oil type, quantity, and torque specifications when reinstalling the drain plug.
Do you need a new drain plug every oil change?
Not always. Many drain plugs are reusable, but it is recommended to replace the crush washer or gasket with every oil change to prevent leaks. If the plug is damaged, corroded, or stripped, replacing the entire plug is necessary.
Final Thoughts
The oil drain plug is a small but critical component located at the lowest point of your engine’s oil pan. While its general placement is consistent across most vehicles, variations exist based on drivetrain, vehicle type, and protective covers.
Understanding its location ensures safe, efficient oil changes and helps prevent costly mistakes. Whether you drive a compact sedan, rugged SUV, motorcycle, or diesel truck, taking a few minutes to identify the correct drain plug will make routine maintenance much easier.
