The BMW 2002tii has a thin cogged belt that drives a cogged belt pulley from the V-belt pulley, which in turn drives the injection pump. This belt should be checked periodically for signs of wear. Should the belt break, the car is immobile.< The belt's location is found to the right of the fan (looking at the engine from the front) at a 45 degree angle. The belt is housed under a black plastic dust cover which when detached by loosening four bolts, reveals the cogged belt for inspection. Cogged belt renewal is described in Section 13 52101, page 13-52/1 of the workshop manual. I suggest that a copy be made of this one-page section and that it be kept in the glove compartment for reference. A spare belt, BMW part 13 521259 269 should be ordered from your dealer whether you plan to replace it yourself or to have someone else do it. There is a good possibility that the dealer will not have it when you need it, so at $10.95 it’s a good investment. There have been failures at under 18,000 miles and at over 50,000 miles.
