I have a 2002 honda civic with 85k miles the dealer says the timing belt should be replaced. But with the water pump timing belt tensioner also have to be replaced???
It relies upon on the vehicle, in diverse fashions, like maximum mitsubishis, you could desire to take the timing belt off to alter the water pump. So then that is an included operation and there is not any extra suitable value linked with the exertions to do the timing belt, it merely makes it a handy, value saving time to do it. there is not any rule approximately changing water pumps and timing belts at the same time. If that is not an included operation there is not any element to do them on a similar time. The timing belt is physically powerful preventative upkeep yet there is not any might desire to alter the water pump previously that is showing signs and indicators, and there are a brilliant style of them, that that is going to die.
Just did this myself. You should replace the belt and water pump at the same time. The water pump is not a durable device, the pump seal will eventually start to leak. Getting your timing belt wet is a sure way to lead to a catastrophic engine failure. I replaced the belt tensioner as well. It's good insurance and since you're already in the engine, the added cost is small and the potential for failure moderate. This is not a job for an average DIY'r, I have a full shop and many years of experience and still had a hard time doing the job. I suggest you get it done by a pro. Astrobuf
The timing belt drives the water pump in your car. To replace the water pump, you have to remove the timing belt. When you are having the timing belt replaced, it makes sense to also replace the water pump. There is very little additional labor to do so, as the timing belt is already removed. You do not have to do so, but if you do not, and the water pump subsequently fails, you will be paying the full labor charge to replace it rather than just the cost of the part. As to the belt tensioner, I would replace that because it is a wear item, and if it fails it can cause a timing belt failure. If you are going to risk the timing belt failing (and causing major damage to the engine) you might as well not have the belt replaced. I would never replace a timing belt without also replacing the water pump and tensioner. It is false economy to do so.
The engine in your car makes the difference the 1.7 has a water pump driven by the timing belt and the 2.0 has an external water pump driven by the serpentine belt so find out what you have but if it is the 1.7 just do it.
I agree with the dealer.It may sound like he is trying to jack up the job but in fact it will save you money and grief in the long run. Getting to those parts is so labor intensive that if you have to go back in later to change the pump or tensioner pulleys it will cost you the same as it did to have the belt changed. The other thing if the pump starts leaking on a new belt you will have to have it replaced again. Whenever I do a timing belt I change everything that is in there. Then I don't have to worry about it.
