Timing belt replacement '99 3.0 Mitsubishi

It still makes no sense. You are saying that CA has a law on the books
that says that belts must be good for x miles? In fact that is what I
have heard in the past, and you'd think that would either drive the
market to two different belts (one for CA cars, one for all others) or
standardizing on the better belt and the one change interval. If it's a
durability standard, then if they're using the same belt, how does that
work out to two change interval recommendations?

As far as I'm concerned, we still don't have an answer on this - the
situation can't be totally explained by two different tailpipe standards
nor by two different durability standards (since there aren't two
different belts - one for the CA car and one for the EPA car).

If it's the same belt, it seems like the consumer ought to go by the CA
car interval whether it's a CA car or not.

I have a Mitsubishi 3.0L in a 3000GT. It called for timing belt and spark
plug replacement at 60K miles. I did the water pump too at 60K and 120K.
Mine is a dual cam model. I only mention this since I don't know if the
Minivan model was also dual cam (I would think it would be).

Again, it has nothing to do with the belt durability (the
standard), it is the emissions system durability standard.
The EPA and CARB can not dictate a standard which addresses when
the engine stops running because of a jumped or broken timing
belt because it is not their jurisdiction, they can however
dictate standards that address whether a component allows
emissions to exceed their standards and whether a component
effects the monitoring of those standards.

The consumer ought to go by what makes sense for their own
particular situation, which has nothing to do with state lines
and/or emissions regulations.
I've changed hundreds of these belts and have yet to see one fail
before 110K miles that wasn't due to an oil leak or a coolant
leak.

 

No, the 3.0 used in chrysler mini-vans is a SOHC engine.

 

Thanks for the clarification. This may well explain the shorter interval
since the belt will be a different part number (longer) and be stressed more
for the dual cam. (I did not think that the 60K recommendation had changed
for the Stealth/3000GT in later model years.

My 97 Caravan manual (owner and service) also state 60,000

 

ahhh simple they want to sell more belts
