Flushing Engine With Diesel Coolant Geling On Diesel Engine?

Coolant Geling on Diesel Engine? - flushing engine with diesel

I rebuilt Cummins 5.9L (Komatso mark) and fill the rad with a 50/50 water / glycol. After running a few days ago that the engine began to run hot (210 ° F), which was initally installed a new thermostat so I thought it might be defective from the factory, removing and emptying the liquid cooling. Once coolandtwas into a bucket and I saw a lot of coolant in the top of the rad and gelled into the bucket. Real-time in the open air from 80 to 95 degrees F every day so it Geling not cold. The wheel wash will be when the engine was turned off. Someone knows why it should freeze coolant in hot weather? Can a small amount of waste reduced annually due cooling gel? When Cummins rebuilt heads for coating the inside of the head with a chemical that will not rust, is sitting on thePlatform could, so as to cause coolant gelling agent? I have converted hundreds of diesel engines and have never seen that experianced. The gel is contained at a high level of silicon, and took a sample sent for analysis. Also for the cooling system and filled with water directly. Let's see what happens, I suppose.
