It might have happened due from the heat up which I've seen before and only running 50/50 could do it.

 

what do you guys think of this...Chris

 

It's kind of blurry. I'm thinking the coolant may have been breaking down and when that happens it starts producing voltage. If you have any coolant left in there stick a voltmeter probe in there and see what you get. Once your cooling system turns into a "battery" it can start eating up components.

 

It could be cavitation. This would do 2 things and would include impeller damage however. But consitering the damage is to the softer metal it might have gone there instead but I don't know why. Still not sure eather way.

If the bearing was ****y from the start everytime you stepped on the throttle would put different pressures on it causing the impeller to touch creating a spot for decomposition to begin. Crap floating around in the system and breaking off when exstream temps happen seem more likely. Durring this, cavitation is deninatly going to happen in my opinion because of differences in pressure and the added heat.

Check this out direct from Prestone®

Q. What is the best antifreeze/coolant concentration for a vehicle? Can I use 100% antifreeze?
A. We recommend that you use between a 50% and 70% concentration of antifreeze. At least 50% is necessary to give the adequate amount of corrosion protection, as well as freeze/boilover protection. However, we do not recommend more than 70% antifreeze. This would cause restriction of the heat transfer capabilities, corrosion protection, and freeze protection. The concentration of freeze/boilover protection of the antifreeze mixture can be checked using a Prestone® Antifreeze Coolant Tester.

I think you are not installing enough for the heat over there and you need to run more like 70% antifreeze and 30% distilled water. Remember to only use distilled water. I would still do that flush and refill with this. Cavitation can occur in this situation in my opinion.

 

I doubt the blade is touching anything on the pump it would be worn smooth. I'm really thinking crap in the system or voltage.

 

C'mon now.. Dont go giving those HHO guys any ideas on alternative power, be seeing a bunch of people with battery cables hooked up to the radiator and pump. Some with missing arms and fingers because the best time to hook up the cables is when the coolants viscosity conducts more energy when the engine is running


*** You could look into using HOAT aswell.

 

Now that's funny.

 

The real funny part is im not kidding either haha

 

^ Smart *** ^

Now this is not the HHO thread so back to the problem boys!


I would suggest that the impeller would smooth of the surface it hits but I'm only trying to find out what could have started this wear and consitering that the bearings have failed, maybe a possibility to start a decomposition trend.

 

I know this is an old thread but I found this in the Service Manual:
