Do it yourself. Three words that are becoming more and more popular in today's economic climate. For most people car repairs are something they can look forward to every year. There are two categories of car repair--major and minor. Changing a timing belt is considered minor, but on a Mazda B2200 it can be a little tricky. If you have the patience and tools, however, you can accomplish this with few complications.
Tools Used: Socket wrench, Crowbar, Flat-head screwdriver, Well-lighted area
Change Timing Belt
Disconnect the negative battery cable. Remove the distributor cap located on the top- right back side of the motor next to the master cylinder.
Remove all the bolts that secure the plastic timing belt cover. You will see the timing cover once you remove the distributor cap. Make a note where each bolt came from, because they're of diverse lengths.
Mark the timing belt with white-out where the two timing marks meet.
Loosen and remove the tension-pulley bolt. It's the on the left with a little spring coming off to the right of the pulley. Hold onto the pulley while loosening the bolt, as it will come away from the housing. Unhook the small spring from the peg and put the pulley aside.
Examine the tensioner pulley for damage such as dents or cracks. Spin the tensioner pulley and listen for a rattle or humming noise that would indicate loose or worn bearings. With the tension on the timing belt relieved, the belt should slide easily off the sprockets.
Reverse the above steps to install the new timing belt.
