Our August episode of The Trainer shared common causes of premature water pump failure and offered a few ways to avoid having a customer comeback caused by something easily avoidable. And our September ASE Question of the Month was focused on the material shared in that video.
Technician A says that worn coolant is a leading cause of premature water pump failure. Technician B says that using a new pump is a wise choice as a reman pump may have unseen defects that might cause premature failure. Who is correct?
Both of our technicians are correct!
Coolant that has become too acidic (loss of its additive package) will lead to erosion on the impeller shaft and shaft bearing, as well as causing other problems in the cooling system - so Technician A is correct. Technician B is also correct. Reman pumps may appear ok but some of the reused components may have defects not visible to the naked eye,.
And you have to know by now, that anyone who takes the time to answer our monthly challenge is also entered in a random drawing to receive a collectible diecast from our series sponsor, Federated Auto Parts!
This month's winner is Greg Hartig of Columbus, Ohio! Congratulations Greg - show off that diecast at home or at the shop.
