Evo 8/9 Timing Belt Replacement

A near step by step instruction on how to replace the timing belt and waterpump on your evo 8 and possibly even the evo 9 CT9A chassis.
Where I got my timing parts, and what tools I needed to complete this job. Parts are from STM
I recommend going slow if you have never done this job before. I am not a professional mechanic but I was able to complete this fairly easily. It does take quite a bit of time however
I used Boosted Films as my reference material on how to complete this project.

Just noticed youtube added commercials to my video. I am not a part of any youtube ad sharing. It seems youtube is doing it themselves. Jerks

Thanks for taking the time to post this video!! I'll be tackling this in the next few months!

[@robinzahnd7325]

Thanks man! I would highly recommand for others to mark the crankshaft-pulley before you loose the belt

[@erik_caves]

Sir thanks for making this vid, I’m about to tackle this on my Evo soon.

[@gbob1980]

Big thanks to u sir. Great video.

Thanks! Timing belt Best video!

[@ohmars310]

Great video! I might attack my evos timing belt

Be careful removing the crank pulley. Spinning it can bend valves. Typically best to bolt something to it to stop it from moving, wedging something in the teeth if replacing, or some other diy method

Thanks for the video. It’s a good addition to the DIY library for Evo owners. One thing you didn’t talk about was making sure the balance shafts are not out of phase. You didn’t mention doing the thing with inserting a screwdriver into the block to check the orientation. How did you know those were okay?

[@d-evolution1309]

Yes I did not cover the part about the balance shafts. I did not for a couple of reasons. 1. I mentioned referencing boosted films youtube channel. He does cover the balance shaft orientation. 2. I did not rotate or spin the crank over or even move the balance shafts while performing this job. Since nothing was moved/rotated I knew everything was right where it should be. The screwdriver into the block trick I am unaware of. Not sure what that is about. Either way I did not have to do that in order to complete this job. On an engine rebuild or near full tear down it would be necessary to verify balance shaft orientation but in my case like I said, I was constantly reverifying that nothing had rotated while doing this job. Thanks for the feedback

You turn the engine over 4 or 5 times by hand and check the tension .

[@martinpreciado3585]

Hey dude when you set the timing belt tension, did your balance shaft marks get out of timing? I saw boosted's video on how that happened to him so he ended up not running it. I want to run it, my question is, did you set the balance shaft mark a tooth back so when you you set the tension it would align accordingly?

[@d-evolution1309]

No I dont believe I did. As far as I remember I kept the balance shaft alignment as is, and just tightened the belt. I dont remember setting anything back to bring into alignment when tightened

[@martinpreciado3585]

@@d-evolution1309 thank you dude!

[@mrsukwoo8257]

When you started the car at the end, did you have the engine supported by the oil pan and also the motor mount off? No problem doing that?

[@d-evolution1309]

Don't remember. It would not hurt anything to do that though

[@airwreck1585]

im assuming that if im not changing the smaller belt. then i dont have to take off the sensor, the second pully and the crank pully socket correct ?

[@d-evolution1309]

Correct. As far as I remember I had to remove all those parts to get the smaller belt off

[@airwreck1585]

@@d-evolution1309 sounds good! i just need to replace my pump. so taking the other things off didnt make sense. Thanks for the help !

[@airwreck1585]

another question. do i have to replace the auto tensioner ? or can i reuse the old one ?

[@d-evolution1309]

@@airwreck1585 you could probably use the old one but the way I see it you are already in there. Might be good to replace it unless you know the mileage on it

[@cornfedevo87]

Hey bud what Ignition system are you running on your Evo?

[@d-evolution1309]

Still on stock ignition. Plugs are gapped around 23 thou. I thought of getting a cop setup but I have no spark blowout so I am going to stick with factory parts

[@cornfedevo87]

@@d-evolution1309 COP kits are not just for spark blowout. With our Innovation-USA Coil-On-Plug kit gains about 8-20 HP and no need for a retune. You will get a smoother idle and yes of course run smaller plug gaps and more boost with any issues.

[@d-evolution1309]

@@cornfedevo87 I was unaware of that. Thanks for the heads up. I'll do some research on it.

[@Ryan_1997]

Crank bolt is a bitch to remove. Note: don’t EVER use an air/electric impact to tighten the bolt. IT MAY BREAK THE BOLT IN THE CRANK. You’ll be RAISING HELL

[@d-evolution1309]

Correct

[@villkar1373]

How much time did you use in total?

Maybe 8 hours?
