Today at 8:09 AM / JD 5403 engine block coolant drain plug #1 R redkar New member Joined Oct 3, 2025 Messages 5 Tractor JD5103, JD5403 I have searched the net and cannot find answer. Where is the engine block drain plug for coolant antifreeze? I see a bolt head on the left side of the engine near the fuel pump, but not sure that's it. TBN is a great site. Thanks.
