Chain. It doesn't need replaced unless it has a problem. Chains don't have a service replacement interval.

How often should timing belts be replaced


Trick question. The 2.7L has a timing chain and not belt. 3.0L needs a new belt every 60,000 but some companies sell a kevlar/nitrile replacement that's supposed to be good for 100K. Do the water pump at the same time. 2.4L needs a belt at 60K.

2006 pontiac vibe getting close to 100K and feel the need to change the timing chain. Someone advised that is this breaks it destroys the whole engine Trying to divert trouble later.


It is personal taste. Some places recommend that timing CHAINS be replaced every 90K-100K, but others drive until there is some change in their engine performance that would indicate the timing chain and then change it. Since you have the timing chain and not the timing belt it is up to you.

Generally, I will replace timing chains IF I have to pull my engine out of the car for any reason, but won't change it at set intervals.

Timing chain on 2003 Suzuki XLT when do you change it? I am at 137,00 miles right now.


Most manufactures recommend changing a timing belt at 100k but I've seen them go several hundred thousand miles and no problem. I've also seen them break under 100k. The best maintenance is preventative maintenance or fixing things before they become a problem. I would recommend replacing it if you have the means to do so as you will also be replacing the water pump which is driven off the timing belt (do them together)..

Does the 1996 Honda Passport have a timing belt or timing chain. If it is a chain, does it need to be replaced at 100K?


It has a timing belt that MUST be changed every 100,000kms..........if it had a chain, then it only needs to be replced when it becomes noisy...

I would suggest also replcing the water pump whilst the belt is off......save time/labour later on down the track....

How many miles for a tune up 2005 chevy trailblazer


Most of the car dealers recommend to perform Maintenance services scheduled at 30K, 50K, 90K and so on.
At 30K they mostly inspect all the systems, and replace fuel filter.
At 60K they inspect systems and flush must of the fluids, transmission oil and filter, coolant, brake fluid, differential and transfer case fluid, and replace the air filter. Some replace the spark plus at 60K some at 100K.
At 90K all timing belts are replaced, and the status of the timing chain checked. A deviation of more than 5 degree means, there it is the time ayes on the timing chain.
At the Owners manual for 2005 Chevrolet Trailblazer recommend:
Inspect all the systems at 25K, and replace fuel filter.
Replace engine air cleaner filter, automatic transmission fluid, automatic transfer case fluid every 50K.
Replace spark plugs every 100K.
Maintenance Services for your car are scheduled at 25K, 50K, 75K,100K and so on. All are tune ups but they are not the same.
The only concern for GM is the GM Dex-Cool antifreeze. There are some complaints regarding this product. I recommend to flush the cooling system every 50K to 60K.

When should the timing belt be changed on a saab vector 1.9 Tid


Standard Answer for Timing Belts/Chains: 100,000 to 120,000 miles is when the Timing Belts/Chains start malfunctioning or failing. Some people want to go ahead and change them before malfunctions/failures happen.
I just replaced mine on 2002 Dodge Grand Caravan which just turned 100K. Most Timing Belt/Chain failures will cause more costly engine damage when these fail, including a need to replace/rebuild an entire engine.

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

2005 Pontiac Vibe: when does the timing belt need to be replaced/checkied


There is no timing belt on this vehicle. Vehicle was produced with a timing chain which generally does not need service through the normal lifespan of the vehicle.

Belt or Chain


Yes those vehicles have timing belts instead of chains. I have yet to see a timing belt that doesnt need to be changed at some point. Maybe the tech meant you didnt need to change them now. Each manufacturer has their own mileage interval, but generally speaking, anywhere between 60,000 and 90,000 miles they are due to be replaced.

Does not require this service, as the motor has no timing belt, it is a maintenance free timing chain.
