What is the best radiator flush and coolant??

[davesl708]

I use Peak Super Cleaner Flush. Run for six hours then drain and flush with distilled water, run for 15 minutes then drain and add AF.
I clean the machine with a leaf blower after working in the summer.

One thing I did notice was the temp was rising before the flush and dropped back a bit but not back to normal. I found the thermostat was warped and not seating properly preventing the radiator from having enough time to cool it. Replaced the thermo and problem solved.

I did a thorough cleaning of my old Farmall radiator earlier this year.

First round was vinegar.
Then Muriatic acid
Then a Gunk brand radiator flush
Then Washing soda.

It was amazing what came out of that thing.

Have not seen this type of flush before. How did you dilute these products
to flush the cooling system?

Does not sound good for the water pump.
