COMPLETE STEP-BY-STEP OIL CHANGE GUIDE
CHANGING THE OIL ON YOUR HONDA NAVI 110 IS ONE OF THE MOST IMPORTANT ROUTINE MAINTENANCE JOBS YOU CAN PERFORM.
IF YOU'VE NEVER CHANGED THE OIL ON A NAVI BEFORE, DON'T WORRY. THIS GUIDE WILL SHOW YOU WHAT OIL TO BUY, WHAT SIZE SOCKETS YOU NEED, HOW TO DRAIN THE OLD OIL, AND HOW TO REFILL THE ENGINE CORRECTLY.
HONDA SPECIFICALLY LISTS PRO HONDA GN4 4-STROKE OIL FOR THE USA AND CANADA, OR AN EQUIVALENT MOTORCYCLE OIL THAT MEETS THE REQUIRED SPECIFICATION.
FOR A STRAIGHTFORWARD OIL CHANGE, A GOOD CHOICE IS:
PRO HONDA GN4 10W-30 4-STROKE MOTORCYCLE OIL
A 1-QUART BOTTLE GIVES YOU ENOUGH OIL FOR A NORMAL OIL CHANGE.
ACCORDING TO THE HONDA NAVI OWNER'S MANUAL:
DO NOT AUTOMATICALLY POUR THE ENTIRE BOTTLE INTO THE ENGINE.
ADD THE OIL GRADUALLY AND CHECK THE OIL LEVEL USING THE PROCEDURE SPECIFIED IN THE HONDA OWNER'S MANUAL.
THE HONDA NAVI 110 HAS A REAR-MOUNTED ENGINE, SIMILAR TO A SCOOTER.
BEFORE REMOVING ANY BOLT, MAKE SURE YOU HAVE IDENTIFIED THE CORRECT ENGINE OIL DRAIN BOLT USING THE OWNER'S MANUAL OR A VERIFIED PHOTO OF YOUR SPECIFIC MODEL.
THE ENGINE OIL DRAIN BOLT IS A 12 MM-HEAD BOLT.
DO NOT CONFUSE THE ENGINE OIL DRAIN BOLT WITH THE FINAL-DRIVE OR TRANSMISSION OIL BOLTS.
START YOUR HONDA NAVI AND LET THE ENGINE RUN FOR SEVERAL MINUTES.
YOU WANT THE ENGINE OIL TO BECOME WARM SO IT FLOWS MORE EASILY.
DO NOT MAKE THE ENGINE EXTREMELY HOT.
TURN THE ENGINE OFF BEFORE BEGINNING THE OIL CHANGE.
PLACE THE NAVI ON A STABLE, LEVEL SURFACE.
LOCATE THE FACTORY 12 MM OIL DRAIN BOLT.
BEFORE REMOVING ANYTHING, PLACE YOUR OIL DRAIN PAN DIRECTLY UNDERNEATH THE DRAIN BOLT.
MAKE SURE THE PAN IS LARGE ENOUGH TO CATCH THE USED ENGINE OIL.
USING YOUR 12 MM SOCKET AND RATCHET, CAREFULLY LOOSEN THE DRAIN BOLT.
ONCE IT IS LOOSE, KEEP THE DRAIN PAN UNDERNEATH THE BOLT AND CAREFULLY REMOVE THE BOLT BY HAND.
THE ENGINE OIL WILL BEGIN DRAINING IMMEDIATELY.
THE OIL MAY BE HOT. WEAR GLOVES AND KEEP YOUR HANDS AWAY FROM THE OIL STREAM.
ALLOW THE OIL TO DRAIN COMPLETELY.
THE FACTORY DRAIN BOLT USES A SEALING WASHER.
INSPECT THE WASHER CAREFULLY.
IF IT IS DAMAGED, CRUSHED, WORN, OR OTHERWISE QUESTIONABLE, REPLACE IT.
HONDA PART #90401-KWP-F00
WIPE THE DRAIN BOLT CLEAN WITH A SHOP TOWEL.
INSPECT THE END OF THE BOLT FOR EXCESSIVE METAL PARTICLES OR DEBRIS.
IF YOU SEE A SIGNIFICANT AMOUNT OF METAL OR ANYTHING THAT LOOKS UNUSUAL, CONSIDER HAVING THE ENGINE INSPECTED BY A QUALIFIED TECHNICIAN.
AFTER THE OIL HAS COMPLETELY DRAINED, INSTALL THE SEALING WASHER AND THREAD THE DRAIN BOLT INTO THE ENGINE BY HAND.
MAKE SURE THE BOLT STARTS EASILY.
IF IT DOESN'T THREAD IN SMOOTHLY BY HAND, REMOVE IT AND CHECK THE THREADS.
ONCE THE BOLT IS PROPERLY INSTALLED, TIGHTEN IT USING A TORQUE WRENCH.
DO NOT OVERTIGHTEN IT.
THE HONDA NAVI USES AN OIL-STRAINER SCREEN.
IF YOU ARE PERFORMING AN OIL CHANGE THAT INCLUDES CLEANING THE STRAINER SCREEN, YOU'LL NEED YOUR 17 MM SOCKET.
REMOVE THE COVER CAREFULLY AND INSPECT THE SCREEN.
CLEAN THE SCREEN THOROUGHLY AND INSPECT IT FOR DEBRIS.
AFTER CLEANING THE STRAINER SCREEN, REINSTALL IT ACCORDING TO HONDA'S SERVICE PROCEDURE.
THE OIL QUANTITY AFTER CLEANING THE STRAINER SCREEN IS APPROXIMATELY:
0.80 L (0.85 US QT)
LOCATE THE OIL FILLER CAP/DIPSTICK ON THE ENGINE.
REMOVE THE CAP/DIPSTICK.
INSERT A FUNNEL INTO THE FILLER OPENING.
SLOWLY ADD PRO HONDA GN4 SAE 10W-30 4-STROKE MOTORCYCLE OIL, OR AN EQUIVALENT OIL MEETING HONDA'S SPECIFICATIONS.
FOR A NORMAL OIL CHANGE, START WITH APPROXIMATELY:
0.70 L / 0.74 US QT
DO NOT DUMP THE ENTIRE BOTTLE IN AT ONCE.
AFTER ADDING THE OIL, CHECK THE LEVEL ACCORDING TO HONDA'S OIL-LEVEL CHECKING PROCEDURE.
THE NAVI SHOULD BE POSITIONED CORRECTLY ON A LEVEL SURFACE.
IF THE OIL LEVEL IS LOW, ADD A SMALL AMOUNT AT A TIME.
THEN CHECK THE LEVEL AGAIN.
THE CORRECT OIL LEVEL IS MORE IMPORTANT THAN SIMPLY ADDING A SPECIFIC AMOUNT OF OIL.
START THE ENGINE AND ALLOW IT TO RUN BRIEFLY.
TURN THE ENGINE OFF.
ALLOW THE OIL TO SETTLE.
THEN CHECK THE OIL LEVEL AGAIN USING HONDA'S RECOMMENDED PROCEDURE.
ADD A SMALL AMOUNT IF NECESSARY.
LOOK UNDERNEATH THE ENGINE AROUND THE DRAIN PLUG.
CHECK CAREFULLY FOR OIL LEAKING AROUND THE DRAIN BOLT OR SEALING WASHER.
STOP THE ENGINE.
DO NOT RIDE THE MOTORCYCLE UNTIL THE SOURCE OF THE LEAK HAS BEEN IDENTIFIED AND CORRECTED.
