MY 97 CAVALIER, Z24 FAILED SMOG TEST, A FEW WEEKS LATER, WATER PUMP STARTED LEAKING. COULD A SMALL WATER PUMP LEAK HAVE BEEN THE REASON FOR THE CAR NOT PASSING THE SMOG TEST??? PLEASE ADVISE. THANKS.
No the water pump will not affect the smog test. You probably failed the idle?
Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.
No, the water pump leak would not cause it to fail the smog test. The only way that could have any bearing on the test results, would be if you lost a lot of coolant, and the car was overheating, then maybe it would have something to do with failing. What were the results (specific #;s and exactly what failed?) Is the check engine light on?
