Timing Belt Replacement Cost Estimate

How is a timing belt replaced?

Replacement involves removal of the timing belt cover and tensioner, the timing belt itself, and, finally the timing belt pulley. It may also be necessary for the motor mounts, engine cooling fans, radiator and other engine accessories to be removed. Installation requires that the proper amount of tension is applied to the timing belt and its related components. Once all the timing parts are back in place, the engine will be tested to make sure it's working right.

Can I replace the timing belt myself?

Because timing belt replacement requires so much deconstruction and putting the right amount of tension on the belt, this repair should be left to a professional mechanic.

What does the average water pump/timing belt cost?

I'm looking at a car and the owner said the car currently has 56k miles but the timing belt/water pump have not been done yet.

Do you guys think at this mileage it's something I should be concerned about? Any other areas I should look at given the mileage? The car is a and about ready to hand over the check.

Here's a good thread regarding all things timing belt/water pump including why it shouldn't be postponed and why the WP is also replaced.

Looks like you're two years overdue at least on your for 90K mile service and TB/WP replacement. Mileage when the time interval is reached is immaterial.
Thanks for the wealth of info guys!

So is it fair to ask the seller to account for the cost of replacement timing belt/water pump if it's overdue? His asking price was $45k and he's thinking the car is a killer deal if he sells to me for $41k ( nsx with just under 56k miles).

I know two things I'll need right away is rear tires and doing the water pump and timing belt which will run me roughly $.....also he just told me the car is on the original clutch as well.

When I bought my 97 with 23K miles I specifically used the overdue TB service as a negotiation issue. I compared to other cars for sale that didn't need the TB.

That said - I'm going against what many here say. My 97 has about 30K miles on it and I am in no hurry to do the TB service. The NSX mechanic at Flatirons Acura in Colorado told me not to worry much. He said the belt is extremely durable, and he has never seen one fail nor have any that he replaced (hundreds) been in poor condition. My car was a cool weather car and not subject to high temperatures routinely.

I'm sorry, but this is very bad advice. I don't know who the mechanic is at Flatirons Acura is but Mark Basch, arguably the most experienced NSX mechanic in the country, as well as other highly respected NSX techs, have confirmed on numerous occasions it is impossible to tell how much life is left on a NSX timing belt just by looking at it. The internal construction of the belt may very well be deteriorating without any obvious outside signs. When TB failure does occur rarely does the belt actually break. The teeth usually just strip off. The elasticity/integrity of the TB is essential to it's effective operation and that simply cannot be determined by visual inspection.

Honda recommends replacing the timing belt at 7 years on a + NSX under all conditions--cold, hot, wet--anything. If the conditions are particularly harsh I would consider changing the TB before the scheduled interval, if anything. I would not risk it. This has been discussed at length here.

Even if the timing belt is fine the water pump might not be. The reason you don't hear about many water pump failures is because almost everyone replaces them with the timing belt. Just one more thing that could break and destroy your engine if you extend your TB service...
