4JH3-TE is low. There was nothing in the overflow tank when we bought the boat
and now the level is also below the cap. Problem is I have no idea what coolant
has been used. It looks orangish but hard to distinguish orange from pink, red etc. (at least it certainly is not green). I got a Delo ELC (premixed 50-50) and from what I read this is a reasonable coolant for Yanmar
. But first, I need to figure out how to flush the existing coolant.
Checking the manual, how many drain plugs there are and where they are is not super clear. From what I read, I *think* there are three but I am not sure. I looked around the engine
and identified three potentials. Attaching the photos. Two are on the port side and one is on the starboard side.
Thoughts if these are the right ones? Being no engine
expert, I don't want to drain something random.
