In high plankton areas like North America's Pacific Northwest, having to change the water maker prefilter once a day is not uncommon. The last change was about ten months ago. The old carbon filter and 5-micron pleated filter from the watermaker after changing. Then we drained the system a final time and added new antifreeze.īecause 1) this worked so well on the generator, 2) the wing antifreeze is due for a change, and 3) the wing antifreeze actually looked fairly poor (you can see how dark it is in the bucket at the bottom right of the photo) we decided to repeat the process on the wing engine. We cleaned that out by draining the coolant, adding one cup of liquid dishwasher detergent and topping it up with water, running it under load for an hour, and then repeatedly draining the coolant and filling it with water, rerunning it and then draining it again until the water came out clean.

But a thin, 1/8-inch gel layer had built up inside the cooling system and remarkably that thin layer of gel was enough to cause the generator to overheat. We believe what was going on is that either there was a mix of incompatible coolants, or the coolant went through some unusual failure mode. This is an unusual procedure, so we had tried many other things first before resorting to this. In tackling an overheat issue with our generator earlier this year, we ended up "washing" the generator coolant circuit with dishwasher detergent.
