Re: Yanmar 4JH2E - how to drain antifreeze?
According to the Seloc manual (for '75-'98 4JH and 4JH2 series engines):
Most engines have the following drains:
> Engine Block: rear of engine above crankshaft centerline.
> Header Tank: at low point of tank
> Expansion Tank: at bottom of tank
> Header Tank: at low point of exchanger.
The book makes it sound like there are petcocks for draining. While they draw many components, there is no illustration of these petcocks. Let me know how you make out. If desired, I can scan the pertainant pages and attach to an email.
