My Junk Car Is Leaking: What to Do Before Pickup

Blog · By Free Junk Car Hauling · Updated · 4 min read

There’s a dark puddle under the car and it’s getting bigger. It’s on your driveway, or maybe worse, it’s running toward the street. You’re going to sell the car anyway, but you can’t leave this to spread until the truck arrives.

You don’t have to fix the leak. Your job is to keep it contained and keep people, pets and storm drains away from it. Here is how, with official contacts for anything bigger than a drip.

Short answer

Do not start the car. If you smell strong fuel, keep people and flames away, and call 911 if it seems dangerous. For a slow drip, put a drip pan under the leak, and keep the fluid away from storm drains and pets. Tell the buyer what’s leaking. Report a spill to 1-800-OILS-911. Do not drain the car yourself or hose it away.

The first five minutes

  1. Notice any fuel smell

    A strong gasoline smell is a fire danger. Keep everyone back, do not smoke or use flames or start anything nearby, and don’t try to fix it. If it seems dangerous, call 911.

  2. Keep kids and pets away

    Antifreeze is poisonous, and it can attract animals. Keep them clear until it’s cleaned up.

  3. Look for where it’s going

    Check the slope. If it’s flowing toward a storm drain, ditch or stream, it’s more urgent. See the table below for who to call.

  4. Put something under it

    Slide a drip pan or an old baking tray under the drip without getting beneath the car. Change it before it fills up.

  5. Leave the car off

    Starting it can make a leak worse and could be a fire risk.

Work out what is leaking

These are common signs, not a diagnosis. Tell the buyer what you see, and don’t taste or sniff anything closely.

What Washington sources say

Most of what we found is aimed at businesses, so we’ll say so where that’s the case.

  • Used oil. Ecology’s used oil page says used oil includes motor oil, brake fluid, hydraulic oil and power steering fluid. Antifreeze is not used oil. Households can call 1-800-RECYCLE.
  • Don’t mix it. Ecology says “Used oil mixed with any solid or dangerous wastes cannot be managed as used oil.” Keep your fluids separate, and ask 1-800-RECYCLE where to take them.
  • Antifreeze. WAC 173-303-522 says “Any discharge of spent antifreeze to the environment constitutes disposal” and is subject to full regulation. That rule is written with waste managers in mind, but the message is plain: don’t let it run onto the ground.
  • Drip pans. Ecology’s Vehicle Recycling Manual tells recyclers to place drip pans under leaks. It’s guidance for businesses, not a rule for you, but the same idea works at home.

Cleaning up a small mess

  • Wear gloves, and keep fluids off your skin.
  • Soak up small amounts with an absorbent such as cat litter.
  • Scoop it into a sealed container and label it with what it is.
  • Call 1-800-RECYCLE and ask where to take it. Don’t put liquid in the trash. Our guide to old oil and antifreeze goes further.
  • Do not hose it down the driveway or into a storm drain.
  • Do not pour it on the ground or burn it.
  • Put a tarp or cardboard under the drip pan if it could overflow, to protect your driveway.

A spill you can’t containEcology says to report spills at 1-800-OILS-911, 24 hours a day

What not to do

  • Don’t drain the car yourself to “fix” the leak. You would then have gallons of fluid to deal with. Vehicles we buy go to auto steel recyclers, where fluids are drained.
  • Don’t drive it to a shop or yard. A brake fluid or fuel leak can make it unsafe.
  • Don’t crawl under it to find the source.
  • Don’t pay for a repair just to stop a drip on a car you’re selling. A drip pan is cheaper.

Tell the buyer

Say so when you call: “It’s leaking what looks like oil, from the front, slowly.” The driver can then plan for it. Take your drip pans out of the way when the truck comes, and stand clear during loading. Our pickup checklist covers the rest of the day.

Common questions

The vehicle doesn’t need to run, but tell us what’s leaking and how much when you call, and we will tell you what we can do. If you smell strong fuel, keep clear and deal with the safety problem first.
