Q4s timing belt

First of all, Im new here, so I want to say HELLO to everyone!
Now heres the thing: Ive just bought a 1994 155 Q4, with 76,000 kms; and the owner told me he has never changed the timing belt yet!
I have to pick up the car next sunday... what should I do?? How can I tell its about to leave me walking?? Or if I cant do so... what treatment do you suggest I can give to the car until Monday morning, when its time for me get the belts and have them changed!!
Thanks in advance, and cheers to you all.

P.S.: Ups! Ive just realized that you can all know I am new, just be reading my category!!! Sorry...

Hiya Tango (great name!)

Welcome to the forum

Firstly.........don't panic!!! wink

How about driving your new car straight to a garage and getting it changed?

The iinterval for timing belt changes on the V6's and Twinspark cars is 72,000 miles but this is thought to be too long and most people reckon 48-50 is best.

Don't know if its the same for the Q4, Alex or one of the other Q4 owners will advise on that.

Enjoy your beauty and hope you stick around for a while

Welcome to the forum!

Amazing that the belt has done its job for 76000 km's. Recommended interval by AR is 60000 km, but most garages recommend 30000 km's. Many of theese engines has had a cambelt failure already at around 40000 km's, so you should be careful. What you can do is to open the cambelt cover on the right side of the engine and just see how the belt looks. But of course take it easy on your way to the garage.

Normally a lot of specialists recommend that the belt gets changed every 2 years or 30,000 km to be safe - a belt going can get quite expensive. When I got mine the guy said he had had it changed but couldn't produce the receipt so I got it done anyway to be on the safe side. Budget for 250-300 from someone who knows what they are doing.

My advice, take it easy, don't thrash the car & get it to a garage & the belts done - you should also get the ballance belt done at the same time.

Have fun wink you'll spend a fortune on it but they are worth every penny!

the Q4 belt isnt too hard to do but you MUST do the balance shaft belt at the same time.you dont need those stupid cam locks either its all marked up.

Guys: thank you all for your replies and suggestions.

I have already spoke with a guy who owns a garage AND a Q4 here in Buenos Aires, so hopefully the car will be inside for belts change first thing monday morning.

I only hope it makes it from the place Im picking it up, till the garage!!

The fact that the belts lasted over 70,000 kms is amazing for me too, that is why Im so afraid!

Anyway... thanks again for your welcome, and you can bet Ill stick around for a while!! This page is owesome!!!

Congratulations Tango for your Q4 and welcome!

Concerning the timing belt on that engine i can give you a few advices:
Official maintenance information says: "changing the timing gear drive belt every 120.000 km" only. Well, that seems much in comparison to what the other guys said. I guess it also depends on the way the car has been driven!
On the other hand, on my Q4 i had the timing belt broken at about 90.000 km!!! It was a lot of work taking down the cylinder head and changing all 16 valves. BUT: It was not the belt that was too old or so, it was a small screw that fixes a sheet metal cover inside the path of the timing belt that untightened itself by motor vibrations, fallen into the belt's drive path and teared the timing and balance shaft belts into pieces. So be very, very careful when you remount your new belts and covers. Fix all the screws around there very well with Loctite!!!
To change the belts you will have to lift your car at the right front wheel, take the wheel and the covers inside the wheel housing off and eventually take down one bar that holds the engine to the chassis (the one upside next to the water reservoirs). Everything should be logic after that. You don't need any special tools. There's not much space round there, but it's possible to do.
Have fun with your car!!
