The concept is to cool and condense steam heading for the Degas Bottle, back into liquid to lower pressure, reducing the chance of over pressuring the cooling system, thereby lowering the chance or amount of coolant released by the pressure cap.
So far, the results are to blow a very small amount at 200 degrees under load, going up a long grade.
Previously, before the cooler/condenser, the coolant system would blow coolant starting at 196 - 198 degrees going up a long grade. At 20 plus degrees, previously, the coolant would blow.all over under the hood.
The headgaskets have not failed in this engine. This is purely a heat, expansion, pressure, cavitation, steam, issue. The condenser needs to lay flat, level, and able to freely flow steam v***r through the cooler to the Degas Bottle. A different orientation would impede the flow of steam v***r through the condenser and impede function.
I believe I'm on the right track to remedy the problem. The next step is to replace the antifreeze coolant with CATERPILLAR Anti Cavitation Coolant.
We shall see if that does the trick...
