Engine & DrivetrainDiscussions about the engine and drivetrain of your vehicle.
This is a discussion thread titled "Belt/Tensioner squeak", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
I know this was brought up in some earlier threads, but I was wondering how many members have had to have their serpentine belts or tensioners replaced. I have started to hear the sqeaking noise sometimes at start-up, and then after it's been running awhile, it seems to go away. The noise started at about 9,500 miles, comes and goes, and of course when I took it in to have it checked at the dealer, they could not duplicate it! They told me to bring it in as soon as it does it again, but it's a tricky devil to catch!
I'm finally getting mine replaced this Tues. After several tries I decided to leave the truck at the dealership over night which finally did the trick.
I'm not exactly sure, but judging by some earlier posts it sounds more like the belt. I started mine up this morning (damp weather), drove a half mile up to the Sheetz to get my paper and coffee before work, and when I got out, it sounded like a cricket was in the front of the engine. Not real loud, but a shrill chirping. When I went home from work, no noise. I think I might have to do like ra1nman, and leave it overnight at the dealer's so they can hear it.
Brought my truck by the dealership last Fri. to get my "chirping" checked out and was lucky because it was a hot day and once you start it up it doesn't last long. But with the hood open the guy barely heard and said he would replace the belt - no problem. He said it can't just be tightened up. Getting it done wednesday morning. I have 24,000 miles so I'm catching it just before the warranty runs out.
Mine started squeeking at around 50K. I let it go unitl 60K and replaced the belt. Nice and quiet now. Keep the old belt as a backup emergency belt (unless you already carry a new one).
It's really nice having a serpentine belt as it is much easier to change than the older trucks with 3 belts! But when the serp goes...you're stranded....unless you have another one with you.
I carry a new one, and it took my dealership 3 days to get it! So, maybe it's a good thing to order ahead of time and carry with you. They are simple to change in the field.
That's a good tip about the extra belt, leadsled. Even if you don't need it, the piece of mind knowing you won't be stranded and waiting for the dealer to get one is worth it. It looks like all you need to replace one is a pry bar or large screwdriver.
I stopped by my dealer today after work, and the chirping was still audible. The service writer got a technician out to my truck and he listened, and said it sounds like the tensioner. He also said the Corollas had some bad tensioners, too. So they are going to replace that and the belt. I can't complain about my dealer, they order and replace any warranty items promptly and with no hassles at all. Their regular service is good, too.
I was having a tensioner problem also. It actually sounds more like an exhaust leak. I can hear it most while accelerating with the windows down and driving by a building. It gives an echo that is easily heard. I brought the truck to the dealer on Monday of this week and they replaced the tensioner. Two days later the sound is louder than ever. Time to go back to the dealer again.

One interesting thing about the Tundra V8 is that although the radiator fan appears to be mounted to the front of the water pump like domestic V8s, the water pump is actually driven on the backside by the timing belt. The fan pulley only drives the fan (its mounted to a bracket directly over the water pump). So as long as you have sufficient speed to keep airflow up and enough battery charge to power the fuel pump & ignition you COULD continue to drive a Tundra V8 even if the serpentine belt breaks -- at least 10-15 miles, maybe more at highway speeds.
