So anytime I buy antifreeze at the local parts store, they try to sell me water pump lubricant. I dont have noisy bearing in my pump, and my cooling system works fine.
<br/> But last time I was there, the guy was pushy and so I stumped him with a question I'd like to know:
<br/> "How could the water pump get lubricated if the additive is in the antifreeze?"
<br/> I mean, if the additive can reach the bearing of my pump, then I dont need lubrication, I need a shaft seal!
<br/> Any thoughts?
