Hi there,

I'm coming up on 60k and calling around for some estimates on a timing belt replacement for my 04 Outlander LS AWD.

Should I automatically replace the water pump as well, even if there's nothing apparently wrong with it once they get the belts off? Has anyone had it go bad on them?

Is there any reason to avoid a non-Mitsu shop for this job if I have them do the water pump?

Thanks for your advice.

I presume you are at 60000 miles and not Kms. I have 163000Kms on my Outlander and I had my belt changed at 105000Kms. The water pump was not changed at this point because the mechanic said he had never seen one go bad before the 200000km mark. But what you should make sure they have in stock before they start the job is an idler pulley assembly which you should change at the same time as the timing belt. They showed me mine and beleive me it was wore out. A little water pump leak can waite until your next belt change but if the idler goes your up the creek and so is your timing belt and maybe a few valves.
On your second timing belt change then you replace the water pump and idler again.

Thanks, Outy. I'm a U.S. American, so yeah, it's miles.

I'll hold off on the water pump for now then. Appreciate the tip on the idler pulley. I'll ask about it before I schedule an appointment.

Just curious - how many of us changed the T-belt at 60K per Mitsu's schedule? I got both the T-belt and water pump done at 80K because 60K was just way too soon in my cheap opinion. I had the work done at an independent shop, but they used Mitsu parts. The dealership hours just aren't convienent for me. I certainly applaud anyone who has/will do it at 60K though. BTW, my pulleys were fine and didn't need to be changed, but I've got the non MIVEC model. Mitsu made a host of technical changes on the 04 MIVEC powered Outlander. I've got a list of the differences between the 2.4L and MIVEC 2.4L; if anyone is interested, let me know and I'll post them or email them directly to you.

Mike

I had the timing belt changed before 100000kms just so powertrain warranty would be continued. I agree that this timing belt agenda is premature because I inspected the belts and they showed no obvious signs to be changed at this time. But the idler was a different story the bearing was definitely showing signs of fatigue. It was loose and greaseless. So was the serpentine idler that had started to scream every cold morning. Mine is the MIVEC and as 2 belts in the timing mechanism one for timing and one for the balance shaft.

So I went ahead and got an estimate at an independent shop, and I have a couple follow up questions, one of which Outy may have already answered:

1. The estimate includes a balance shaft belt in addition to the timing belt. But based on Outy's last post, that sounds right since I have an 04 with the 2.4 MIVEC.

2. The part cost for the timing belt (MD336149) is quoted at $82.78, which seems high to me. Does that include additional components? Or is that just a really "high end" belt?

Thanks.

That seems about right. Wait until you price the serpentine belt.

Last time I purchased this kit:433$

One of the bearings was wrong but they have since rectified this problem so I'm told. I'm due for a new kit and will get the same one.

I would recommend the belt be changed every 100,000Kms.

My lil 00UTY is almost at 400,000Kms now (reading 399,605) and I have religiously had the timing belt changed every 100K - and the engine is fine with no problems thus far.

With regard to the water pump - It finally gave up (the reason I know is that the poor 00UTY built up enough pressure in the coolant to split the top of my radiator!) at just before I had the 300,000K service done.
The guys at Mitsi found that the water pump was wearing out (see above sentence!) and all the timing belt guide rollers needed replacing too as they had worn.

Bear in mind that this 'extra' work was only required at 300,000Kms, so unless your Outty has gone that far everything should be fine.

As long as you are using a mechanic who knows his job, the water pump, pulley rollers, etc should all be inspected anyway whilst he has the front of the engine open for the timing belt change.

Hope this info helps!

Cheers,
00UTY
