Thanks For the reply H. I called purple power and they do not recommend using thier producer on aluminum. Warm soapy water it is.
The tube in the overflow tank was plugged with rusty muddy crap. And I mean plugged. I could not stick a rod through it. I had to hammer it through. Can't find a new tube so it looks like I will have to make one. It is steel tube 5/16 OD and 4-5/8 long.
What the.. have you ever serviced your cooling system? Nasty nasty.
Going by memory on that tube you can take a flaring tool and flare the end out as seen on the factory tube.
FYI I drain and replace my coolant every year on ATV's and RV, this reminds me I need to change the anti freeze on both my tractors this year.
For coolant I use Distilled water mixed with coolant 50/50 this makes 2 gallons then add 1-2 drops of dawn dish soap to each gallon and 1 Teaspoon of baking soda to each gallon and shake well.
Soap breaks the surface tension of the water makes liquids bond cling to metal better (like water wetter stuff does) the baking soda neutralizes acids in the coolant system been doing this for 30 + years.
Good time to change automotive coolant is before it reaches 1/2 volt DC , you can test by removing the radiator cap (when cold) and putting a volt meter on low range and DC voltage and connecting the negative (black) to the negative of your battery then putting the positive (Red) probe in the coolant inside the radiator not touching metal, read the volts I have seen them as high as 1 volt DC.
I remember in the early 80's they had many problems with the autos computers giving problems because the coolant voltage was too high (usually approaching 1 volt the problems start) that's when I started with the soap and baking soda treatment.
Show me pics of everything after you clean and flush.
Wonder what the inside of your
Engine coolant passages looks like is it possible to remove the hose from the water pump and see if you have gunk by the impeller in your Pilots current state of disassembly? Had the head off or the top end apart recently ?
Any gunk on the inside of the hoses?
