How long/many miles should v belts last? Much noise makes mine need replacing after 11,000 miles/11 years. Seems a bit early. What is your experience? Much advance thanks for your response.

I think the years are more of an issue than the miles. I'd replace belts every 5-6 years on these cars.

What kind of noise does it make? Never heard of a noisy belt, other than one that's too loose and squeals. But in that case you don't need a new belt, you just need to remove a shim.

A properly adjusted v-belt will last a very long time.

Oh absolutely this! One can try and squeeze out as much life as possible for v-belts, but I don’t roll those dice on any car I or my family has owned!

In my mind, there is always some kind of maintenance that a car needs where adding in a belt replacement simply makes sense from a preventative maintenance standpoint. This on any car, let alone a 993 where it’s so easy to do. Getting stranded with a broken belt is just one of those things that really should never happen …and given how cheap and easy it is to replace periodically it’s just not worth trying to get more life out of an $8 part.

Manufacturers recommend 3-4 years or 30-40k miles whichever comes first….I have gone longer with 5 years with adjustments being good….

I've owned my 993 for 8 years and have yet to do my belts. I"m going to do them over winter because Rennlist put the fear in me.

I would replace them due to age. By chance is the noise possibly coming from the belt sensor which is notorious for making such noises as the device ages?

Hi Ronnie,
If the correct belts are used, the factory pulley update has been applied and a tensioning gauge is used to install them, I replace them about 15k miles due to use on my daily driver 993, not sure about how many years a belt should be kept on an example of a low mile where the belt simply dries out from age. If the tensioning is adjusted during routine maintenance the belts can last a good bit longer. Something that few if anyone does as adjusting the belts is over half the work of just replacing them/

Further belt stuff is discussed at the bottom of this page:

The alternative is to install an aftermarket ribbed belt system discussed on this page:

I keep an extra set of belts in my car's frunk along with the tools to replace them for use if I get stranded in the middle of nowhere, something one may encounter in certain parts here in Texas.

How about fan belt? I usually replace all my belts every 5-6 years regardless… just for a piece of mind.

Is the nice looking woman in your profile picture just adjusting or is she replacing one of her belts?

Thanks guys. It was the original sensor that made the noise but belts were replaced as well. Apparently, they're susceptible to degradation over time and heat cycles similar to tires. Sensor and 2 belts were cheap at $244 Northern Pesos but 3 hours labour due to intercooler removal really added up. Gbos1, I must upgrade my avatar. Very tasty.

Hi Ronnie,
For the future, if you touch the side of the sensors roller wheel with a tiny dab of white lithium grease, or for that matter most any grease, including Crisco, on your fingertip, at each oil change one extends the life of the sensor pretty much indefinitely.

ROFL….one of her “belts” let loose when she got out of the car

Great tip Andy.
