250-500cc Water in oil

I don't see any really good sources presently in an internet search this morning, but I do some firsthand experience with the old style inexpensive automotive coolant....in a truck. I was running this stuff in my truck for years. After about 13 years, my alternator quit working and I had it replaced. The technician who did the replacement, put a cooling hose back in place with the protective split sleeve in the wrong position. About a year later. I noticed that the car began to run hot one day, so I checked the coolant. It was quite low, so I filled the radiator and tank up, but noticed that there seemed to be dried coolant all over the alternator.. I discovered that the hose was touching the alternator in one spot, where the protective sleeve was split. The alternator had made a hole in the hose, causing coolant to spurt out right into the alternator. I pulled the brushes from the alternator, and they were completely worn out. I bought new brushes and put them in. The alternator worked properly for another three years, but then began to make some noise. This time, the bearings were shot. I have never seen bearings go bad in any alternator in any car that I have owned, and I put a lot of mileage on my vehicles. Brushes should not wear out in a year's time. I'm pretty sure that the silicates in the coolant caused the brushes and bearings to go south prematurely in the alternator. I don't run that "old style" coolant in my truck or any of my other vehicles anymore.

Right out of my Honda CR manual.
