2009 Acura MDX Serpentine Belt Diagram: A DIY Fix
Taking a look at a 2009 acura mdx serpentine belt diagram can be quite much mandatory when you're trying in order to swap out a good old, squeaky belt without losing your own mind. If you've ever tried in order to guess the redirecting on a Honda-made V6, you know it's not exactly intuitive. One particular wrong turn around a pulley plus you're left with a belt that's either three ins too long or even way too short.
The 2009 MDX is a beast associated with a luxury SUV, but your best engines require a little TLC once they strike that 100, 000-mile mark. That single rubber belt—often known as a drive belt or accessory belt—is responsible for running your alternator, your power steering, as well as your air conditioning. If it snaps, you're not just stuck without AC; you're stuck on the particular side from the road with an useless battery and simply no way to steer.

The 3. 7L V6 engine within this year's MDX is a little bit cramped. When a person open the engine and look over the passenger side, presently there isn't an entire lot of "elbow room. " Most of the time, there should become a small sticker under the hood displaying the belt's route, but those activities peel off off or obtain covered in dust after a decade on the highway.
Without a visual reference, it's simple to neglect if the belt goes over or under the tensioner. Since the belt provides both a ribbed side along with an easy side, it offers in order to touch the pulleys in a specific way. Ribbed components of the belt touch the ribbed pulleys; the smooth back of the belt touches the smooth idler pulleys. In the event that you flip that will logic, you'll burn through a new belt in regarding a few minutes flat.
Getting Ready for the Swap
Before you even contact a wrench, make sure the engine is great. You're going in order to be jamming your own hands into some tight spaces near the engine block out, and those components hold heat for the long time.
You'll need a few basic tools: * A 14mm wrench (preferably a long-handled a single or a dedicated serpentine belt tool). * A brand-new high-quality serpentine belt. * A torch (it gets darkish down with the crankshaft). * A telephone to take a "before" picture—seriously, do that even if you have a diagram.
It's the good idea in order to inspect the pulleys while the belt is off. If you see a pulley has a lot of play or makes the grinding sound when you spin this by hand, the particular belt wasn't your own only problem.
Learning the Tensioner
The very center of this job is the automatic belt tensioner. It's a spring-loaded arm designed to keep your belt tight because it stretches over period. On the 2009 MDX, the tensioner will be located roughly in the middle of the accessory commute.
To produce the tension, you'll place your 14mm wrench on the bolt head in the particular center of the tensioner pulley. You're likely to rotate this counter-clockwise . This pushes the arm apart from the belt, giving you more than enough slack to slip the belt off the topmost pulley (usually the power steerage pump).
Don't be surprised if it takes a bit of muscle tissue. Those springs are usually stiff for a reason. If you're utilizing a standard brief wrench, you may struggle. This is where the long-handled tool or even even a "cheater bar" (an item of pipe more than your wrench) arrives in handy to obtain that extra power.
The Redirecting Path Explained
When you're looking at your 2009 acura mdx serpentine belt diagram , you'll see the belt makes a sort of "S" curve with the middle. Here is usually the general flow from the best down:
- Power Steering Water pump: This is right at the particular top. It's generally the easiest place to start or finish the particular installation.
- Alternator: The belt goes from the power steering pump more than to the alternator, which sits towards the front of the car.
- Idler Pulley: From the particular alternator, the belt falls and wraps round the smooth idler pulley.
- A/C Compressor: It after that heads down to the particular very bottom front side of the motor to operate a vehicle the AC.
- Crankshaft Pulley: This is actually the big man at the bottom. This pulley offers the power to everything else.
- Tensioner Pulley: Finally, the belt loops back up, going around the tensioner before returning to the power steering water pump.
It sounds simple enough when you write it away, but when you're leaning over the fender and can't view the bottom pulleys, it feels like a puzzle. The most typical mistake is skipping the idler pulley or trying to route the belt on the wrong side from the tensioner.
Placing the New Belt On
The particular trick for you to get the particular new belt upon without getting disappointed is to begin at the bottom. Twine the belt close to the crankshaft pulley first, then the particular AC compressor. These types of are the toughest to reach, which means you want them seated properly before a person start considering the particular top.
Make use of one hand in order to keep tension on the belt so it doesn't slip off the bottom ribs. Loop it around the particular alternator and the idler pulley. With this point, you should have the loop of slack near the energy steering pump plus the tensioner.
Now, grab your wrench and rotate the tensioner counter-clockwise again. While holding the tensioner open with one hand, make use of your other hands to slide the particular belt over the power steering water pump pulley. Once it's on, slowly allow the tensioner proceed.
The particular Final Check
Don't just close the hood and call it the day. You need to double-check that the belt is perfectly concentrated on every single pulley. When the belt is hanging away the edge of the pulley by even one rib, it is going to shred the time you start the car.
Run your fingers along the pulleys (with the engine off, obviously) in order to feel if the belt is seated within the grooves. In the event that everything looks directly, go ahead plus start the engine. Let it idle for a minute and listen. You're searching for a smooth, silent hum. If a person hear chirping or a loud punch, shut it down immediately and examine the alignment again.
When to Replace the Belt
Many people wait till they hear that annoying "morning squeal" to check their belt. That high-pitched sound usually happens since the belt offers lost its grip or the plastic has hardened.
However, contemporary EPDM belts (like the one upon your 2009 MDX) don't always break like the aged ones did. Rather, the grooves simply wear down heavy, sort of like the tread on the wheel. You can buy a cheap plastic gauge to check the depth, but a good rule of thumb is to just change it every a hundred, 000 miles or in case you see any fraying on the particular edges.
The Few Pro Guidelines
If you're having a tough time having the belt to stay within the bottom pulleys as you work on the particular top, you may use the small piece of cardboard or even a zip tie up to lightly support the belt against the crank pulley. Simply remember to get rid of it before you tighten everything up!
Also, if you find that the tensioner doesn't move very easily or feels "gritty, " it's most likely time to replace the whole tensioner assembly. It's a bit more work, but it's much cheaper than having a frozen tensioner snap your brand-new belt fourteen days from now.
Working on an Acura may be a little intimidating because almost everything is packed in so tightly, but a serpentine belt change is one associated with those jobs that really saves you a chunk of transformation in the mechanic. Simply keep that 2009 acura mdx serpentine belt diagram visible on your own phone or printed out nearby, and you'll be simply fine. It's a squeeze, and a person might lose a little skin on your knuckles, however the satisfaction of a quiet engine is usually totally worth it.
