I have to replace my waterpump on my 93 jeep grand cherokee 4.0 6cylinder engine, because it's leaking water. The waterpump only has about 5000miles on it which makes me really mad, but the fan clutch was never replaced when we replaced the waterpump. I've read that I need to replace the fan clutch when replacing the waterpump. And then, I've also heard that you don't have to replace the fan clutch when replacing a waterpump. Can you tell me if I should go ahead and change the fan clutch?
