Hi, I'm a new member here, as well as a new owner of a 2001 MPV with the 2.5 V6 engine. After hours of searching the 'net' and the owners manual, I had the same question. I gave up searching and called a local Mazda dealer and asked the Service Manager, he answered that the 2.5 V6 has a metal timing chain, that does not need changed, as a 'timing belt' would every 60k miles. I'm sorry for not knowing if the 3.0 V6 has the same. I was all set to buy a Chrysler Product, but in my hours of research (wife's words)into the 'sto n go', I came across the Mazda MPV and Honda Odyssey, with the back seat that folds into the floor, and the middle seats that slide together. After driving the Chrysler Town and Country and the Honda, I didn't like the sizes of them, they are too long and hard to judge the length of, when parking and/or backing up. I then found the MPV so I went to look at it and ended up driving it home. A Fold Flat Rear Seat, plus Side Windows that roll down in the Sliding Doors I still find it hard to believe that a quality van made in Japan, sent all around the world, has a 'Ford' engine, and it has a Timing Chain, taking into consideration the added costs of maintenance for changing a Timing Belt every 60,000 vs fixing the Timing Chain when it breaks, hopefully somewhere between 150,000 to 200,000 or more miles. Chaulk 1 up for Us, the consumer for once ! There seems to be a lot of complaints about the 2000 and 2001 year models with the 2.5 V6, 4 sp Auto trans, lacking power, but coming out of a 1994 Mazda B2300 (Ford Ranger in disguise) 2.3 L I4 with a manual trans, and before that a 1982 VW Rabbit 'L' Diesel. This van has lots of power. ZOOM ZOOM !
There is no recommended replacement interval given for the chain replacement timing belts are critical, chains are not.
the 2001 does not have a timing belt,instead a timing chain,which does not required replacement as often as belt
It is the chain that turns the cam. It does not require replacement under normal conditions and it normally replaced during an engine rebuild.
CR-V engines are equipped wiht timing BELTS not chains. The factory recommended replacement interval is 105,000 miles.
A timing chain does not need to be replaced. Sometimes they can go bad and will make noise, or can get a bad link, requiring replacement. Timing BELTS require periodic replacement because they are rubber and wear out over time. Chains are good until they experience mechanical breakdown due to excessive wear.
Timing chains will normally last the life of the engine and are replaced during a complete engine rebuild. Therefore, no maintenance is required.
Timing chain usually needs to be replaced each 180-200K miles.
The chain will last the life if the engine and does not require changing.
A timing chain will normally last the life of the engine and is replaced during a complete engine rebuild.
If the engine has a timing belt, it should be changed around the 150K mark. If there is a timing chain, it does not have to be changed unless it is damaged.
It has a chain. No recommended replacement interval.
