No to the first question. I do not know the answer to the second one.

It does not contain any silicates or phosphates, but I would not recommend this for a diesel engine as it may not protect the water jackets. Try hunting for a jug of either Final Charge Global or Fleetguard designed for diesel engines. Mix with distilled water if you are doing a full coolant change. City, well, drinking, spring water is bad and will cause scale to form.
Also make sure it is the fairly new ELC coolant which doesn't require SCA as they use inhibitors and protection superior to that of older coolants using silicates or phosphates which require SCA.

No it does not contain silicates. look at the msds on google.com or bing.com. Not really to sure if it is cummins certified though. Some cummins take Dex-cool and sum take conventional green. I think peak antifreeze is cummins certified and super tech is made by old world industries (same as peak antifreeze). To be honest being an ase mechanic as long as you do a complete flush and fill you wont have a problem. Have been running super tech 50/50 in all my Fords and Jeeps and never had a problem. Hope this helps you!!!
