are you talking about a tractor that has been sitting thru last winter?…or do ya live in Arctic circle? It will not crack block unless it’s in freezing tempts. The issue running straight water in summer months isn’t cracked block…it’s corrosion, which leads to clogged water jackets and overheating.Hi!
What is the Likelihood of cracked engine block when having only pure water in the cooler? Is there some room in engine for the water to expand when freezing?
yea it will corrode…you can’t evacuate all the water and moisture + air = corrosion. Just fill it with good antifreeze and your set.Yes. I dont know the tractors history and this winter we had 14 days with sudden freezing temps. 4-5 C. The water in cooler is yellow but it freezes.
Havent thought of corrossion. Looks like there is some anti corossion additive in the coolant liquid you buy.
For the future for this engine and any other I am thinking of just leaving it drained during winter time. Im only using the tractor a few times a year from spring to fall.
Will an empty tank corrode more than aone filled with coolant?
Not me. Tractors get conventional (green) AF and the cars get extended life (Global AF which is orange). Wife's Burb gets Dexcool and Green and orange don't mix well. Turns to goo.
Not correct....If you are running 100% non diluted of any type of coolant then you will have issues. When coolant gets too concentrated, it “gells up” and turns to a jello like substance.
Only if you mix different types, example extended life and conventional green. Concentration has nothing to do with 'jelling up' and everything to do with heat transfer. Straight AF will not transfer heat as efficiently as a 50-50 mix. Water is still the best heat transfer medium but it freezes. You could actually fill the cooling system with diesel and it would work, just not efficiently transfer heat. Many modern motorcycle engines use crankcase oil as coolant.
Better yet, care to substantiate your claim with a valid link? If not, I'd say it's phooey. How about it?
Do these links qualify for unsquidly's statement that I also agree with?? Simple test is pour some 100% antifreeze in a container & place container in your deep freeze for a few hoursBetter yet, care to substantiate your claim with a valid link? If not, I'd say it's phooey. How about it?
Exactly.I’ve relied on manufacture specs for coolant….none report to use straight AF…the type of antifreeze varies and I comply with specs. I always assumed they knew best and figured it depended on the type of metals used in the engine and cooling system…cast and copper or stainless etc.
Before the premix AF we used to use the antifreeze gage to determine if more water or AF was needed in the system. I’ve never heard of this being a point of contention honestly.
