Question type: Maintenance & Repair

I have a 2005 Toyota Highlander with 130,000 miles. Is it possible to drive another
10,000 miles before getting the timing belt replaced?

It should of been done at 90k all so change the water pump and the hoses as well the belts.

Timing belts should be replaced each 60,000 miles. So you're already 10,000 miles overdue. You may be able to go another 10,000 miles or it may break tomorrow. If the timing belt does break serious engine damage can result costing thousands of dollars to fix! I'd replace it now. HTH. -Jim

That's unlike a regular belt that shows wear. It will break with no warning and when it does your engine will stop within 1 second. Possibly with a valve embedded in the cylinder .... that's the definition of "Boat Anchor"

Yesterday we test drove at a dealer a 2005 Highlander with about 125,000 miles, the dealer just replaced the timing belt. Extensive CarFax maintenance report, one owner.. I will of course have the car checked by a mechanic. I am trying to forecast cost of ownership of this car over the next 5 years, driving about 7,000 miles a year primarily local. Need advice whether these Highlander models with so many miles are values, (price is ballpark $10K). I don't want the larger models post-2008, and we also drove a used Venza ($ 20K) and a used RAV4 V6 (21K) last week.

I have about 200,000 miles on my 05 highlander. Only had to replace the alternator

Is it 4 cylinder engine or a 6? The 2005 4 cyl Highlander has a timing chain, not a timing belt. Timing chains are rated for much longer life than the belt, which is on the 6 cyl engines. 4's are rare. You probably have a 6, but you know which you have.

Just to be safe I like to change mine at every oil change. I drive mostly highway and use fully synthetic Royal Purple engine oil with a K&N filter so I only change my oil about every 5,000 miles.

Yaris_10885 above must be referring to a serpentine/fan belt....not a timing belt!

Either way, Darren, that's excessive. Serpentine belts are good for 50,000 to 60,000 miles. The serpentine belt should be inspected for wear at each oil change and replaced if the tensioner is near the end of it's travel, the belt is "chunking" (losing chunks of the ribbed rubber), or fraying. Otherwise you'll be wasting money. HTH. - Jim


I had my timing belt replaced on my 2007 Highlander when it had 94,000 miles. The replacement timing belt just broke yesterday at 154,000 miles so it obviously did not make it another 90,000 on this second timing belt. I wonder if it common for the timing belt to break sooner with older cars?

Please consider that an engine with 150k probably has more internal friction than a new engine .. so the belt works harder. .. Just my thoughts but to me it makes sense

140k and will be my first timing belt replacement for 2002 Highlander.


you're at least 40,000 mi on borrowed time

Manual on V6 calls for timing belt to be replaced at 90K. I did mine at 100K along with water pump (which is a bear to get to). Subsequent timing belt changes should occur every 100K thereafter, because of age and possible degradation of the Kevlar belt. Realistically, anybody who brags they've only changed oil or alternator on a vehicle with 200K miles is lucky and not wise.

Getting mine done at 135k. While at it I am getting the water pump taken care of it too. Why pay the same labor for both the belt and pump as they are around the same location and will cost me the same labor if I had to replace the pump separately.

205,000 miles on a 2003 V6. The timing belt has never been replaced.


is it necessary to replace pulleys and tensioner when the timing belt and water pump are replaced. Some mechanics say yes and other say no, confused.


Do the tensioner and the idler wheels! If they fail the whole thing fails!


The mechanic said he could check them when he replaces the timing belt and tell if they need to be replaced or not and if they look fine he say they will not need to be done at this timing belt change. 100,000 miles 2006 Toyota Highlander 6 cylinder gas


Saving a couple of dollars on an idler wheel is going to seem really stupid if your $5,000 engine fails!

Should the camshaft seals be replaced when changing timing belt or just checked, some say to replace some say no. Still trying to come up with money for waterpump/timing belt lit but in the Aisin kit I think the seals are included

The Toyota dealership says my water pump and timing belt on a 2008 Toyota Hylander Hybrid with 75,000 miles need to both be replaced. I am seeking another opinion from another shop. There is nothing leaking on the floor of my garage. What do you think?

1 of 1 people found this helpful.

Replace the water pump with the timing belt if the water pump is driven by the timing belt. The water pump may last another 75,000 miles or it may not. If not you have to pay for the labor to replace it all over again. In the long run you'll be saving money. HTH. -Jim
