Dealing With Coolant System Pressure and Temperature

Question

VIDEO Dealing With Coolant System Pressure And Temperature VIDEO

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 200 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, vapor, issue. The condenser needs to lay flat, level, and able to freely flow steam vapor through the cooler to the Degas Bottle. A different orientation causing pooling or accumulation, would impede the flow of steam vapor 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...

Hope you get this resolved.&nbsp; I left a note on your tube page about my experience with cavitation caused an aftermarket coolant pump impeller clearance to the housing.&nbsp;&nbsp;I see that you have a picture of what looks like the pump impeller.Jim

As always, glad you have something to fiddle with to occupy your time and you appear to enjoy it. &nbsp;But holy moly, sure is a lot of trouble and work and $ when there’s many brands and models of diesel trucks with none of these issues to worry aboot. &nbsp;
