[C320-list] 3YM Coolant Question..

[Jon Vez]

Thanks Kurt--I'll have to wait until I drain the Yanmar coolant before I can
use off the shelf stuff. How does that plug unscrew. Mine seems to be a plug
with a circlip type clamp. Not sure how it opens up....

Regards,

Jon Vez

Jon,

Once a year I drain my coolant by unscrewing the plug at the lower front
right of the 3YM-30 engine into a bucket.  It is just less than 1 gallon.
Then I refill from top right of engine right under bulkhead with Dexcool
50/50.   I can find that at Walmart or any auto supply store
