TB + rollers replacement job

[cody at 5000tq.com]

I'm with them too except that I also recomend water pumps when they  
are t-belt driven, especially in 1.8t's with the plastic impellors. I  
can't tell you how many times I've gotten a timing belt off and found  
the water pump to be leaking slightly or worse.

Think of it this way.. on the (dohc) v6 Audi's the belt interval is  
usually 105,00 miles. The water pump is generally thought of as being  
good for that, but do you expect it to last to 210,000 next time the  
belt is off? I don't. 90% of the time the cost of replacing it while  
the belt is off is a hell of a lot better then what it would take to  
take the belt off again to do the water pump when it goes bad 10,000  
miles later.
