Electric Water Pump damage
What is causing this damage to the inside of my electric water pump, and what can I do to stop it. I run just water in the system,and drain it in the fall.

Re: Electric Water Pump damage
I always understood when you let air get to wet metal it still corroded. I always leave the water in. How about electrolysis?

Re: Electric Water Pump damage
Lyn run the Lucas (* it works) cooling system additive or the redline water wetter. Both are good for aluminum blocks/heads/intakes/water pumps. It won’t allow it to corrode

Lyn,
Wix, #24056 cooling system treatment is also a good product and available at most auto parts stores. It is around $7.00 per quart.

Re: Electric Water Pump damage
What fluid do you run in the coolant system? Tap water could have some metals that will attack aluminum. Excess acidity can corrode it to. Check the Ph level of the water you use with a test kit. I run distilled water only and drained the block and pulled the water pump to change the cam this week. Lots of rust in the water but no damage to the WP.

Re: Electric Water Pump damage
The debate will continue about what water to use. I do know that some coolant additives state not to use distilled water. I stick to filtered drinking water for my car.

Re: Electric Water Pump damage
It happens in washing machines too. Go figure.
