Mazda Timing Belt Replacement

If the water pump is leaking, it needs replacement. Timing belt is replaced at certain mileage intervals . You can have the belt inspected by a garage. The timing belt does not have to be changed to replace the water pump. If a timing belt is changed, then it is standard procedure to change the water pump, since the water pump is removed when replacing the timing belt.

Your timing belt should be replaced every 50-70,000 miles. Carmakers have specified the replacement intervals for timing belts. In this database you will find these timing belt replacement intervals along with a little technical information regarding the valve configuration - interference or non-interference. In an interference engine, the valves and piston share the same air space. They never touch, unless your timing belt breaks or skips, and this is a catastrophic failure that requires removing the head and replacing bent valves. Non-interference engines do not risk this contact if the timing belt goes. Nonetheless, either can leave you stranded, so regular timing belt replacement is very important.

Your water pump is driven by your timing belt, can not be seen with out remove timing belt cover, to replace you will also have to remove timing belt, if timing belt has not been replace best to replace it now also, timing belt should be replace every 60,000 miles. make sure before removing timing belt that you mark where all pulley gear's are at, so when you install the timing belt back on there in the same place as before you move the timing belt, no need to mark water pump gear,good luck,hope this was very helpful.

Average replacement mileage for a timing belt is around 60,000 miles. Many cars I have purchased had over 100,000 miles on them and had never had the belt replaced. Try to use original equipment belts or high quality after market belts when replacing. Cheap belts will not last as long and could cause serious problems if neglected(example cheap alternator belts will squeak, stretch easily, and not hold up.). I always replace all the belts when doing a job this intense. If your car has high miles it is a good idea to replace the water pump at the same time you do the timing belt.

Belt is better replace either about every 100.000 or you'll destroy the engine when it goes out

Belt is Better because it's easier to replace, therefore much cheaper

Chain is inside and in the oil bath so harder= more expensive

By the way. dealer says replace every 60K . 100K is a MAXIMUM

Somewhere between 90,000 mil;es and 120,000 miles you should do your timing belt. But first make sure you do not have a timg chain. If you have a timing chain, you never have to change it at all.
