and also what is a good price for this service? should i replace the water pump etc when i do this? my car has 70,000 mi btw. i know honda suggests (i think) between 60,000 and 80,000 mi or every 8yrs if my memory serves me correctly.

I do beleive its 7 years or 105,000 miles. When you change it out i would recommend changing the water pump, drive belts and seals..If you pay to have it done its probly going to cost $400 to $700 bucks depending on where you get it done, you can also tackle the project yourself for the price of parts and your time..

Some Sis have timing chain not a belt; the chain can last longer than the belt and won't need replacement as frequent. also, for the timing belt job it's good idea to replace the cam and crank seals and check the tensioners and pulleys. i did my timing belt at 110k and it cost me around $325. if you do it yourself, you need to be very careful, i know a friend whose car broke down on the highway after a timing belt job

04 SI has a chain, not a belt.
Engine is on the passengers (right) side.
2.0 K motor.
No replacement interval as long as the right oil has been used and changed regularly.
The chains don't put up with neglect.

FYI- This is especially important on DOHC engines.

so does anyone know which the 2004 si has? a chain or a belt? and if it is a chain should i still replace the water pump, seals and etc soon with my car having 70,000 miles on it?

All civic Si from 02 to present use Chain..(correct me if i am wrong)

If your car is running fine then i wouldn't mess with it yet.. When it comes time to for it to be done unless you are familiar with changing them i would pay to get it done right, if you mess it up it will cost thousands to repair instead of hundreds...

so it has a chain? ok thanks.

does anyone know signs that its going bad? i was just told that you wouldnt know when it was going but when it did it would be bad :/ so i igured i would just follow hondas maintenance recomendations and replace it. not myself mind you.

What does your owners manual say about replacing the timing chain as a maintenance item? Look in the maintenance section where it lists when to change fluids and filters and stuff. (I didn't look.)




I have seen one SI engine that jumped time. I have no idea if it made any noises or gave any warning though.

The engine was "low maintenance", neglected the oil changes and/or didn't use the correct oil.
He*l, the entire car was "low maintenance" for that matter.
