Losing maybe a shot glass of coolant
per 4 hours of run time. I can see drips and splatters under the turbo and on the saildrive
. I've been trying to track this down for months now. Today I found a possible clue.
The charge air cooler (after cooler) has a drain hole at the bottom (see picture below) that is supposed to drip out water
condensate from hot air flowing over the exchanger element. It vents a good stream of air as it should, and probably some condensate as designed. But it is appears to also be spitting (sometimes, and only a tiny bit) yellow/green coolant
so maybe this is where I'm losing coolant?
BUT! IF (??) I understand correctly the air cooler uses SEAWATER not coolant in its exchanger. So I'm a bit baffled... I know the air cooler can, normally, burp some oil
from the turbo. And the splatter seems maybe a little oily. But it's definitely coolant colored.
Anyone have a suggestion or insight on what is going on? Thank you!!!
