I'm looking at purchasing the new Hyundai Veloster. My brothe informed me that Hyundai timing belts have to be hcanged every 60,00 miles. what about the Veloster? It has a timing chain. Does that make a difference?

There appears to be no strip down or servicing information. You just replace then at $700 a go!

I was thinking there is probably a shear pin between the exhaust fan and the intake fan. Nothing on my theory.

Well the car is older now it sounds like something in the timing. When's the last time the timing belt was changed? Research is needed is it a timing chain or a timing belt? Belts should be changed every 60,00 miles or you risk a break and that permanently damages some engines.
Other things that effect timing are the ignition system, spark plugs, wire set, and also the fuel injectors could effect the RPMs. Ask YouTube and see if there are answers there too.

First let me tell you that the canister purge valve is covered under warranty for 5years 60,000 miles ! Anyway it is located to the rear of the cylinder head above the block/trans mounting area

Well since you never say engine not sure it even has a timing belt, but if it does 100,000 miles would be the interval and 60,00 on the engine accessory drive belts.

pull the timing belt cover and have a look. get a manual or hope u-tube has it.

I know for a lot a vehicle you put your key on all light came on then press three time the accelerator after start your engine and check it out this procedure work's for a lot of manufacturing.

The engine dies when the belt breaks.
Can also do major damage to the engine.
Most car brands recommend replacing at 60,00 to 80,000 miles.

You should find another dealer. Hyundai recommends replacing the belt every 60,000 miles and this dealer knows this. No reason at all to replace it at 42,093 miles. Remember that this is an interference engine so if the belt breaks serious engine damage will occur. Do not neglect this service at 60,000 miles.

look at mileage. the replacement of the timing belt needs to be done at 60,000 miles. you risk severe damage if this is not done. these belts costs around $300-400 to do.

timing belt and most drive belts are good for 70,000miles, i think the mechanic trying to take you for a ride, as for the drive belts inspect them if there is any cracking ware marks etc replace them but seriously if they look like new which they should with only that many miles would not need replacing.
