cooling flush

[shadowdancer]

got a question.
I have taken off, cleaned, and pressure tested the heat exchanger and put it back on

I would like to flush the system and add new coolant.

1. can I fill the cooling system with a flushing mix in run the engine for a short time, then dispose the mixture ( I removed the thermostat) or should I use water

2 where is the best place to drain the mixture

3 what is the direction of flow or does it matter ?

I have a westerbeke w-58

Have you read the Operation Manual or doesn't it cover your question?

Personally, I just flush with fresh water, drain by disconnecting the lowest hose, refit hose and fill with appropriate coolant. I would replace the thermostat.

Our engine service manual recommends just that. Happens they also recommend their preferred product (Fleetguard Restore) for flushing.

You might check your own manufacturer's recommendations.
