Timing belt question

[jhun35]

I was reading on here that the GS has a timing and driveline/balancing belt or something like that. I was wanting to replace my timing belt and get a new underdrive pulley (2006+ Mitshubishi Eclipse (2.4 MIVEC) RRE Underdrive Pulley Kit Sport Compact Auto & Import Performance Superstore) is this pulley for the timing belt or the other one? And if it is not for the timing belt where would be the best place to get a new one? Sorry, I'm the most intelligent when it comes to mechanics of a vehicle. Not something I took a lot of time to learn yet. But thanks for any help!

[Chris05]

Are you trying to replace it or upgrade it? The one you found is the upgrade

[jhun35]

I wanna upgrade the pulley definitely. I'm slowly modding the car. I just didn't know if the pulley and belt I found was the timing belt or the other belt the GS has.

Timing belt doesn't have a pulley my dude. It has sprockets and tensioners.

[jhun35]

Okay, so the pulley is for the other belt then. Where would be a good place to find the replacement timing belt?

[jhun35]

2006 Mitsubishi Eclipse Timing Belt - Gates W0133-1767123 <---would this be all i need?

[dsm2mivec]

There are two timing belts on a gs and they only send you the front belt! Im a little worried when you say your not that familiar with mechanics bc you probably are gonna have to pull the motor and our timing belts are sorta crazy

Good luck though

[jhun35]

I'm not gonna be the one putting it on lol I would probably mess something up pretty bad. I'll be doing it with my dad and uncle more than likely. But if they only send the front belt where would I get the other one?

[b1gkishan]

There is only one timing belt. The other one is for a balance shaft.

[dsm2mivec]

If I'm not mistaken can't you use the balance shaft eliminator kit out of the evo x

[mrgibs121]

the belt can be replaced with the engine in the car, its just a hugeeee pain in the ass. you can do the underdrive pulley yourself. took me only about an hour. i would definitely have the belt done at a shop tho. be expecting a 600+ dollar bill for the job

[jhun35]

Okay I see now. My fiance's step dad owns a shop so I may be able to get him to let us do it there. Because $600 is ridiculous for maintanence. So the pulley i seen with the belt that comes with it would be for the balance shaft, which shouldn't be hard to do from reading other people talk about it online. Just the timing belt is going to be the annoying part.

[dsm2mivec]

Haha no that pulley is for your serp belt the balance shaft belt is behind the timing belt

[jhun35]

Damn, okay, got it haha. Do I need to replace the balance shaft belt also? One of my belts squeel's really awfully when it's really rainy or cold and just started this about two months ago.

[nokiauser]

Squealing is usually caused by a worn out serpentine belt.

[jhun35]

Oh wow, you're right. lol I don't know what I'm talking about. I know my car could use a replacement timing belt (115,000 miles :/) and I want the lighter and smaller underdrive pulley as a mod. But I can get a new serpentine belt right now and put that on. I for some reason just assumed it was my timing belt because I knew I needed to reaplce it lol. Thanks for all the help tho guys.

[b1gkishan]

You better replace the timing belt ASAP with those miles. They get dry rotted and get cracks. You don't want a timing belt to pop ...they don't make noises to let you know they are going bad lol. If it pops you looking at cpl grand worth of damage vs 500$ timing belt job and water pump job.

[Scottishsamurai]

when do you usaully replace the timing belt? about how many miles give or take?

[roman lujan]

100,000 miles

I'm going to this month. I'm going to get the underdrive pulley, a new timing belt, waterpump and serpentine belt and do it all at once.

[mwaterous]

Do the UDP yourself for the experience, it's a ridiculously easy install and a great way to get wet behind the ears (showering is another great way to get wet behind the ears, but that only gives you two extra torques).

The only thing I'd recommend is getting into the habit immediately of either taping the screws you pull out (of the splash guards, etc) to the hole they go back in, or placing them in an area that will remain untouched in a pattern you would remember a week later. Otherwise you will put them back in wrong, or lose one which is almost as bad.

Also the UDP comes with the new belt you need, don't buy that separately unless you need a spare. Keep the little cardboard shell that comes with it so you know what model number to get if you ever do need a replacement.

I had a timing belt go out on a Ford Escort, on the Las Vegas strip of all places... thankfully the Escort 2.0l sohc is a non-interference engine, but at the time my knowledge of diagnosing was pretty limited and I tried turning it over a few times before we figured it out.

Try that on an Eclipse and you might as well write it off and get a new one.

^this is my biggest worry. I know they can cause a ton of damage. :/ that still sucks though man.

All these people helping you out and not a single erep doled out to answer your questions? Kids these days.

stripped the T-belt on my 4G69 lancer at around 4k rpm...no damage...of course i didn't know until i removed the head. but i skipped the compression test and just pulled it cause i assumed being an interference engine that i was going to find holes in my pistons, or smashed valves, or something terrible, but the pistons actually made very little contact with the exhaust valves only...

HOWEVER! it did cost me around $900 to repair, and i did all the work myself, except for machining the head, reseated and lapped valves etc. was done professionally, and cost around $300...the rest was shipping and parts...the gaskets and timing belts kit was very pricey...

I was all repped out yesterday and the day before from the e-rape thread. I got you today though.

[FeaRlezZ]

im not looking forward to doing a timing belt on this car. . . luckily i should still have a long time before that day comes

[chad_a_alex]

Hey guys. I'm coming up on 60k and going to be doing the timing and balance shaft belts myself. I'm not questioning my ability to do the work, but I'm curious to know if I should buy any of the special tools? If I should, any recommended sites to buy them from would be greatly appreciated. Thanks in advance for any advice.

If you're seriously considering replacing your timing belt go here: http://tearstone.com/eclipsefsm/2006...000500-11A.pdf
Section 11A-50 has the drawings, component names, and torque specs you need to know. At 115 k miles In addition to both timing belts I would also recommend replacing (or at least closely inspecting) the tensioner and idler pulleys.

[akley88]

i have to do mine soon. im just gonna replace everything while im in there

[CrAnSwIcK]

good call...there's actually a really sweet video on youtube someone did for a 4G69 timing belt job...pretty sure it's an eclipse, but same engine as us Lancer RA...

anyways great visual how-to, should use the manual as well, but it helps to actually see it

[Jonrod]

Not something that is simple by any means. I had one strip 12 teeth on me, luckily I had no valve damage.

[CrAnSwIcK]

same here, my belt was stripped in two spots opposite eachother on the belt, so they were competing on which side would fail first...but no valve damage...

inspect your timing belt often!

[B-bo4]

be sure to change out your timing belt man! at 60k miles bc my car is now in the shop and i may have done some major dammage....

How many miles were you at when your timing belt gave out?

Just hit 100,000 luckly I had no valve damage! But it was about 500$ to get the belt replaced but to get the valves replaced would have been anywhere from 1500-2500 according to the people at my shop.. So if you have more than 60k def a good idea to start thinking about getting a new belt

Yeah, I guess it could have been worse, it costs about $550 to get the timing belt and water pump replaced.

This thread is an excellent example of how a $1-200 set of tools can pay for themselves quite quickly. Putting the cost of quality parts and nice tools against a mechanics shop on just the timing belt alone and you're still coming out $100 ahead at the least.
