Coolants

[CuckooCox@aol.com]

Here in the Southwest, the temp often gets up into the 100s during the 
summer.  That's a bit warm for my TR-3 to say the least, especially in 
traffic.  I've seen a product called "Stops Overheating" made by ProBlend 
Chemical which claims to reduce engine temperature by (up to) 40 degrees.  It 
retails for about $20/Qt.  
Does anyone know if it really works on these little tractor engines or if 
there are other products that work?
