Those episodes of rough idling this morning were classic symptoms of a leaking vacuum hose, so check your vacuum line for problems. As you know, computers installed in modern vehicles largely depend on vacuum to know exactly what's going on with the engine and other parts. If your car is leaking vacuum because of a punctured or torn hose, your vehicle's computer may be forced to operate in a fuel-rich mode to avoid a lean mixture of air and fuel that could result in catastrophic engine damage. Of course, that doesn't mean your car is ok, either. When you were roughly idling this morning, your engine's speed was actually fluctuating because your computer was finding it hard to achieve equilibrium. Continue driving with a busted hose and your fuel mileage will significantly drop and other parts of your vehicle may sustain damage, including your engine. So if you hate paying big bucks at the auto repair shop, replace your old stock now with a new, heavy-duty vacuum hose, which you can get here at Auto Parts Warehouse. Our massive collection of over 550,000 top-quality auto parts and accessories ensures that you'll get an affordable hose regardless of your make or model. Go ahead and add a new vacuum hose to your cart today to feel the best performance from your car and avoid huge repair bills looming on the horizon.

Engine Repair Basics: Replacing a Leaking Vacuum Hose

Your vehicle's vacuum hoses basically control a lot of its emissions components, engine response, and even environmental controls. Once a vacuum hose has been damaged, your engine may experience performance problems which may lead to a non-starting engine. To avoid headaches and expensive repair bills, replace the vacuum hoses before it's too late.

Here are the steps, tips, and tools we prepared to help you find and replace the leaky vacuum hose.

Difficulty Level: Easy

Tools that You'll Need:

  • Old rags
  • A pair of pliers
  • A can of carburetor cleaner
  • Flat-head and Phillips screwdrivers
  • Brand new vacuum hose

Tips and Reminders:

  • Let your vehicle's engine cool first before working on the engine's vacuum hoses.
  • Make sure that your vehicle's parking brake is engaged before starting the engine.
  • Check your replacement parts and make sure that they are compatible to your vehicle's make and model.
  • Always wear recommended safety equipment like closed-toe shoes, an industrial-grade dust mask, safety goggles and gloves.
  • Step 1: Open your vehicle's hood and check the vacuum hoses in the engine compartment.

    Step 2: Inspect all the vacuum hoses for cracks and other signs of damage.

    Step 3: Turn the engine on and spray carburetor cleaner on each of the vacuum hoses. Listen for any changes in the engine's idle noise.

    Step 4: If you hear a change in the engine's idling noise or a hissing sound, locate the damaged hose and turn the engine off.

    Step 5: Use a pair of pliers to slowly pull the leaking vacuum hose off its plastic or metal connectors. Be careful not to damage any of the connectors.

    Step 6: Use an old rag to carefully clean the vacuum hose's connectors. Make sure that these are free from dirt, dust, and oil before installing the new vacuum hose.

    Step 7: Remove the new hoses from their packaging, and inspect them for any cracks or damage.

    Step 8: Apply the right amount of pressure when inserting the new hoses into its plastic or metal connectors to avoid damaging the connectors.

    Step 9: Start the engine and spray carburetor cleaner on the new hoses to verify if the repairs were done properly. Listen for any changes in the engine's idling sound.

    Replacing the damaged vacuum hose will take about 30 minutes for an expert DIYer and around 40 minutes for a beginner. It's a relatively easy project, so have fun with it!
