In case you're staring from a 2015 toyota highlander serpentine belt diagram plus wondering where to even start, don't worry—it looks course of action more confusing as opposed to the way it actually is usually once you make your hands dirty.

Most 2015 Highlanders on the highway are rocking the 3. 5L V6 engine. It's a workhorse, yet the engine bay is pretty loaded, which makes viewing the belt routing a bit of a challenge. When you've ever attempted to "eye-ball" the belt replacement with no a map, you know how quickly issues can go south. One wrong convert around a pulley and suddenly the belt is 3 inches a long time or even spinning the water pump the wrong way. That's why having a solid visual of the routing may be the first thing a person should grab before you even touch a wrench.
Why You Need This Diagram Quick
You may think you'll remember how the belt goes on, but 10 minutes into the job, when you're elbow-deep within the steering wheel well, your memory might get a little fuzzy. The serpentine belt on the 2015 Highlander comes after a certain path throughout the crankshaft pulley, the alternator, the particular power steering pump, the A/C air compressor, and a couple of idler pulleys.
The most important part of the 2015 toyota highlander serpentine belt diagram is identifying the tensioner. On this specific model, the particular tensioner is exactly what keeps the belt tight therefore it doesn't slip. If you don't know which pulley is the tensioner, you're going in order to have trouble getting the old belt off, let alone getting the new one upon.
It's also worth observing that while several cars have a convenient little sticker under the hood showing the belt course-plotting, those stickers tend to peel off or get covered within road grime over the years. Having a digital version or perhaps a printout is the lifesaver when you're trying to figure out if the particular belt explains or under that center idler pulley.
Tools You'll Actually Need
Before you decide to dive in, let's talk about what you need. A person don't need the whole professional shop setup, but the few specific things will make your life a lot easier.
- A 14mm long-handle wrench or a breaker bar: The tensioner bolt on the Highlander is a 14mm. Given that space is tight, a longer wrench gives you the power you need to compress the spring without breaking a sweat.
- A serpentine belt tool (optional yet nice): If you can't fit a regular socket and ratchet in there, these types of flat, skinny pubs are designed exactly for this purpose.
- A flashlight: Even within broad daylight, it's dark down within the side of the engine block.
- Your cell phone: Seriously, have a photo associated with the belt before you consider it off. Make use of the diagram because your primary guide, but an actual photo of your own specific engine helps a lot.
Step by step: Changing the Belt Yourself
In case you've got the bit of DIY spirit, changing this belt is a totally doable Weekend morning project. You'll avoid a good chunk of change on labor expenses, and it's a great way in order to get to understand your Highlander the bit better.
Getting Access
On the 2015 Highlander, you'll still find it much easier to work in case you go through the traveler side wheel well. Raise the entrance right side, consider the tire off, and remove the plastic splash shield. This provides you a direct line of view to the crankshaft and the tensioner. Wanting to do the whole job through the top is really a recipe for scraped knuckles and the lot of discouraged sighing.
Relieving the Tension
Locate the tensioner pulley. Using your 14mm wrench, you're going to rotate the tensioner bolt. On this Toyota V6, you usually rotate it counter-clockwise to produce the particular pressure. When the pressure is off, simply slip the belt off among the top pulleys. Next, the particular tensioner will golf swing back, and you will pull the old belt out.
Redirecting the New Belt
This is usually where the 2015 toyota highlander serpentine belt diagram becomes your best friend. Start through the bottom and work your way up. Loop this throughout the crankshaft first, then snake it around the A/C compressor as well as the other pulleys. The "trick" is to leave the particular most accessible pulley (usually an idler pulley or the alternator) for last.
As soon as the belt is positioned on almost everything except that final pulley, pull the tensioner back once again, slide the belt into place, plus slowly allow the tensioner go. Give the belt a good turn to make sure it's sitting perfectly within the grooves of every pulley. If it's even somewhat off-center, it'll shred itself the second you start the motor.
Signs Your Belt is About to Quit
If you aren't sure if a person actually need to change the belt yet, there are a few "tells" that will Toyota owners should look out with regard to.
- The Squeal: In case your car sounds like a distressed bird every time you start this on the cold early morning or when a person turn the steering wheel all the way, that's belt slip.
- Visible Breaks: Take a look with the ribbed aspect of the belt. If you observe "chunking" (where pieces of the steak are missing) or even lots of small cracks across the particular ribs, it's toast.
- Fraying Edges: If the edges of the belt appearance fuzzy or such as they're unraveling, it's likely misaligned or just old.
- Glazing: If the flat side of the belt appears shiny or "glassy, " it is often obtaining too hot from slipping, and it won't grip the pulleys properly anymore.
Helpful Tips for a Smoother Job
I've done this enough times to learn where the snags usually happen. Very first off, don't buy the cheapest belt you can discover. Choose a reputable brand like Bando (which is usually the particular OEM supplier for Toyota) or Ls. A cheap belt will stretch away faster and start squealing in just a few months, and no one wants to perform this job two times.
Another suggestion: check your idler pulleys while the particular belt is away from. Provide them with a rewrite along with your hand. They will should spin effortlessly and silently. If you hear a grinding noise or if the pulley wobbles, replace this now. It's way easier to do it while the belt is already away from in order to have in order to take everything apart again in two weeks because a showing seized up.
Lastly, make sure the engine is stone-cold. You're likely to be reaching deep into the motor bay, and all those metal parts stay hot for a long period. There's no sense within getting a "mechanic's tattoo" (a burn) because you had been in a hurry.
