I have a 2002 Z71 Suburban 5.3 engine, 75k miles, auto trans. My water pump went out at 60k miles. I replaced it last year at the dealer's service dept. Within 8 months, my sub started leaking coolant. I took it back to them, they pressure tested the water pump and found it to be defective. They replaced the water pump for free since it was under warranty. Now, 2 months later it's leaking again. Other than leaking, the sub runs fine. Since this pump is still under warranty, I want to take it back to the dealer to be serviced but is there anything else I should have them check?
have the same problem?
