One problem related to engine belts and pulleys has been reported for the 1999 Mazda Protege. The most recently reported issues are listed below.
My son purchased a 1999 Mazda Protege lx last year. He has had major problems with the engine running hot. He was told he needed a timing belt and water pump. He had the car fixed at a cost of $750. 00. Again the same thing happened about two months later. He again is being told that he needs the same work done. This time it is going to cost him $900. 00 and the engine has to be tested to see if there is no damage. If there is damage to the engine it will be more costly. Also the power locks are damaged and this occurred the first week of purchase.
