Timing chains do not need changed until they break or get so loose that they jump a tooth on the chain. But if you have a timing belt instead of a timing chain, it does need to be changed before it breaks. Replace the timing belt every 60,000 miles. Severe engine damage will occur if you do not replace the timing belt every 60,000 miles.
You should replace the timing chain every 60-80,000, but if you are like me, I have 300,000 and never changed it. It is all about preventive maintenance. If I had a double overhead cam or something I would have changed it.I have seen timing chains go at 20,000. That's a choice that only you can make. Timing chains break without warning, so a new one is always nice , but personally, I think they just scare you into buying a chain every so many miles, so that you buy another one.Money grab. Good luck
i recommend that anyone have the timing chain or belt changed at 100,000 miles on any car just as a precaution/ preventative maintenance. you dont want to wait til it breaks or gets loose and jumps timing
It has a timing belt. Recommended to be replace every 105,000 miles, timing belt also run's your water pump good idea to also replace, your engine is also an INTERFERENCE ENGINE which will damage your cylinder head valve's if timing belt goes bad. Hope this was very helpful.
WELL BUICK LACROSSE HAVE TIMING CHAIN.THE SERVICE SCHEDULES MAINTENANCE DONT GIVE NO TIME CHANGE.I SEEN TIMING CHAINS LAST OVER 100000 MILES OR MORE.IF YOU NOT A HARD DRIVER.TIMING STILL GOOD.CHAIN OKAY IF YOU HEAR CHAIN NOISES OR YOU NEED TO REPAIR FRONT TIMING COVER SEAL THEN REPLACE TIMING CHAIN.YOU BE THE JUDGE.IM NOT GOING TO TELL YOU NO OR YES.IF YOU GOT THE MONEY.WOULDNT HURT NOTHING.JUST THE COST AND LABOR..
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.
It will not damage the motor (bend the valves) if it breaks or jumps time
Finally, if you do change the belt, make sure that the water pump is inspected very close for any evidence of coolant seepage at the impeller shaft weep hole. If there is ANY evidence of wetness or leakage, replace the pump then. Easier to change the pump when the belt is off, than to have to do the whole job if the leak gets worse, and, if it leaks down the road, coolant on the timing belt will damage the belt, and you will have to buy a new belt, too. Change the plugs at 90 K miles, too.
Until 2002 Toyota's had a timing belt. After 2002, Toyota's have a timing chain. Manufacturer/dealers recommend replacement of the timing chain at about 90,000 miles. I've talked to several mechanics - including the dealer - about the cost of changing out the chain. The lowest price I found from a very reputable mechanic is $260-270. He told me that if I brought in the part, he'd reduce the cost. The dealership was almost double!
Re: water pump: I haven't found anything that stated it must be changed at 70K miles. Hope this was helpful.
