Hey Guys, need some insight. My son recently purchased a 00 catera w/ 75000 miles on it, so we are new to the Catera family. I've been reading thru this forum and find it very helpful to those of us that enjoy messing with our own vehicles. I've seen where it is recommended to change timing belt and idler assy at around 60000 miles, and given that we don't have any maintenance records on the vehicle, I figure I better git r done! Given that we typically do our own maintenance and repairs (I try to take the mentoring role, but typically end up getting my hands dirtier than he does?!) I've found the kit at Rock Auto, but I'm wondering if I'm gonna need any special tools and how much time its gonna take? Any insight would be helful. Thanks

You can perform the replacement yourself but only if you have the V6 Locking Kit. Without it the cams or crank will move from the proper positions and the timing will be shot to hell. Read more courtesy of the Omega Owners Forum and the Catera/Yahoo Group (you may have to register). The VX Network instuctions are for a transverse V6 but once the belt and tensioner are uncovered the rest is the same.

I had mine replaced by a local garage. For just over $300 it was well worth it. There is no way I could have torn down the front of that engine and do it myself.

Great reply Elvin315, lots of great info there. Sounds like a nice little sunday afternoon project for me and my son. I'll be supervising of course?! Probably won't attempt for a week or 2, but when we (he) gets done I'll let you all know how it went.
Thanks aqain elvin315!

Those that can, do. Those that can't, give free internet advise.

I'm jealous. I wish I could do it myself but I don't have the tools, place, or confidence. I used to do this stuff years ago but now that I'm alone, and down to one car, I can't afford to make mistakes that will have it out of commission for very long.

In the UK they just had a cambelt weekend. A mass gathering of Omega owners to help each other maintain their cars. Wish we would do something like that. It would be worth driving a few hundred miles to me just to meet some of you and talk Cateras, eat some burgers, and fix our cars.

That sounds like a great idea, so IDK i am in CHICAGO - DETROIT area so any of the ones around here can probalby do something like that, mine is due for cambelt change in 7K miles and, we can maybe even do some brake swaps or even some other issues... but who has got the garage and tools to provide?
I will be willing to drive a few hundred miles to meet with some of you guys... LEts get a meeting just for a photoshoot and a cruise...

a word of advise......tell your son....do not, i repeat do not jump on the gas. this could cause the belt to jump and miss timing. which will bend minimum 8 valves. yes thats major engine teardown time. i speak from experience.
have fun, robert:thepan:

We are the guys that have the rental kits available. GM tool J-42069.

I just did my wifes 2003 Saturn VUE belt about 6 weeks ago. Not to bad, about a 4 hour job start to finish. Taking my time and pictures etc.

The only problem was my tensioner did not match the GM online service manual for Saturn 2003. Screwed with that for 30-40 minutes. When I looked up 2001 Catera there was the version I had.

The VUE had 120K on before I did the belt. I would cringe everytime she started it. Got into some warm weather so I went ahead and replaced the belt.

We have five J-42069 kits right now.

i love jumping on my cat now.....now that my timing belt, tensioner, heads and 12 bent valves have been replaced by my extended warranty company. at a cost of $4,600. $100 of which i had to pay, and also without a car for three weeks. its running like new now, but if i was suspect of the timing belt or tensioner. i'd be weary, especially with the restrictor engine in this german car.
a word to the wise is sufficiant.

btw. this occured 3 months ago

If you need the complete timing belt tool with instructions, I rent it out for $50.00 a week plus shipping. A few folks on this list have rented it with no problems. You can e mail me for further information at Mail@AutoTechUnlimited.com

I am getting ready to do my timing belt on my '97 that i bought a few weeks ago with 130,000 miles. I did check with the dealer and the mechanical water pump, all pulleys and the belt were changed at 60,000 miles, but as it is well documented, i need to get this changed ASAP. I was planning on buying the timing component kit (includes belt, tensioner, and 2 idlers), the mechanical water pump, and the serpentine belt while is was in there and had everything apart. I was looking at rockauto for all the parts. I have bought a few parts from them already and i have to say, there prices are unmatched by any of the GM wholesale sites and they ship quickly and even answer there phones when you call to ask about a part. I really liked dealing with them.

A few questions for anyone that may have already done this:
1. is there any difference between the GATES TCK285 kit and the ACDELCO TCK285 kits? I have been doing a lot of reading about this and thought i saw someone mention there may be some difference in the belt reference marks or something. Sorry i don't have any specifics regarding posts and where i saw this. The search on this forum isn't very good and i simply can't find the post i am referencing.

2. Does anyone have any pros/cons regarding all the different water pumps available. I won't bother listing all the P/Ns, but they have gates, acdelco, airtex, cardone and so on...just wondering if anyone may have had any bad luck with a particular one.

3. Then of course, same question for the serpentine belt....they have gates, dayco, and acdelco available.

4. Is there anything else i should do while i am in there with everything apart? I know there are a few more things i may have to address soon, such as HCV, oil cooler/exchanger, etc...but didn't remember reading about anything else to do while replacing the timing belt.

I have emailed Tom at Autotechunlimited regarding the alignment tool and am waiting to hear back, so i hope i have everything covered.

I am going to really try to document the hell out of the job with pictures for everyone's future reference when i do this job. I read through several of the european threads that Elvin provided in this thread and others regarding our timing belts and none of them seemed to be as complete as they could be, so i will try to fix us up here on this side of the pond with something similar. I just hope i can post the pics when i get going. I am new here and don't even know if i am allowed to post pics since i don't have many posts yet, but i will certainly try.

thanks and wish me luck:thumbsup:

ive got the kent moore kit that I would be willing to rent out. with printed off step by step directions from gm

You will need the tensioner wrench.

The Kent Moore kit has the tensioner wrench. The Baum kit does not include the wrench. A Craftsman wrench will not work as it is too shallow.

I dont think the 'tom' kit has the needed wrench.

We have a couple Kent Moore kits available, and of course, several Baum kits. Our rental kits include the required wrench. 30 day rental.

As for the engine. Used for about 10 years. The are several configurations. Mostly related the different pulley assemblies etc.

Some Saab's have a adjustable lower tensioner. Many latter (Saturn/Catera) versions have a fixed pully.

Bank 1-2 tensioners. Several different versions available. Also updated tensioners. I think the rule for the tensioners is 'black is bad, brown is good.'

All use the same timing belt. That being said, the belt has paint marks on it for direction of rotation, TDC, and cam marks. But being there is more then 1 version. Most belts have 2 sets of TDC marks, and multiple cam TDC marks. The trick is figuring out which paint marks to use.

It should be noted: TDC marks for both the crank at engine are at the bottom of the engine. Not to be confused with BDC.

The job can be done. IF you have the tool. Certainly easier then installing a TCC transmission solenoid on a Northstar L480 PO741 issue.

Picture is AWD Saturn VUE timing belt change. Using Baum 4145 kit.

I have a lot of pictures of the timing belt in my "engine removal" thread. It might help to see it before you start tearing apart your engine.

yes, I have gone through your thread many, many times. very nice thread BTW. Tons of good information in there. I certainly wasn't trying to slight your thread. I just thought it would be cool to have the timing belt/tensioner procedure itself documented with pictures.

thanks,
