Is our new style LS engines a liner engine if so then we need a coolant supplement ? The only thing my owners manual says is ASTM D5216 that tells me its a Propylene Glycol base engine coolant Automobile and Light-Duty Service, so i would think that would mean that our engine is not a liner engine like the old MF 135 Perkins engine and not need SCA or Supplement coolant additive.
Can't speak for all but my XR4040C (XR4000 series)does not have liners according to service manual , if the repair value is is exceeded ,replace engine block compl...
Personally , I flushed my engine with distilled water and switched to an extended life antifreeze ...not to protect liners (my tractor doesn't have liners "unfortunately") but to protect
Other components of the cooling system...

I really don't know antifreeze. But I know that I have a 2003 JD dozer, got used. A little low on antifreeze. Took the cap off and the inside looked like new. It was really clean. I went back with the best JD antifreeze. I know JD does not make it. They have someone put their name on it. I was told to get the best with the most anti corrosion I could get. Or get an additive to put in it for the water pump and to stop the corrosion.
A good antifreeze is a must...change it as recommended or if voltage exceeds 0,4 volts
.got to be careful sca additives to much they will drop out of suspension plugging your system....
