Ready to tackle this project for the first time. Manual states remove lower radiator hose. Check. Then remove drain plug behind oil filter. Not seeing anything obvious. Picture in manual is not the best. Any help appreciated. Thank you.
The parts illustration seems to show the same drain valve as shown in the Operator's Manual. You are not seeing anything like this in that location?
What's odd is that in the manuals for later serial numbers, even though they too show a block drain plug, they do not have you remove the lower radiator hose or the block drain. They simply have you drain the radiator, fill with water, run until thermostat opens, drain again and re-fill.
