1999 Suzuki DF 60 cooling problem solved!!

[skidmark1]

After installing new water pump, impeller and base plate I still did not have water flow. Decided to try the vinegar cleansing with 3 gallons of 5% acidity white vinegar in 30 gallons water. Ran the motor several times first day until heat buzzer sounded, then let cool. Saw increase in pee pressure late afternoon and vat had crude on bottom. Did not rinse engine. Next day changed the water and added 6 gallons of vinegar and ran the engine again several times that day. By late afternoon had a much stronger pee and could run engine much longer until exhaust heated water. Lots of crude came out in vat. Rinsed it 2 times to get vinegar out.

Ran motor yesterday at lake 2+ hours, idling and wot and it performed perfect. Peeing strong and running cool..

Thanks to all who posted this procedure on this forum, it really works. And only costs $2.40 per gallon for vinegar.
