Step-by-Step Tutorial
1. Gather Your Tools and Safety Gear
Before you start, gather all the necessary tools and put on safety glasses to protect your eyes from flying debris.
2. Measure and Mark the Cut Location
Use a measuring tape or ruler to determine the desired length of the coolant hose. Mark the cut location with a permanent marker.
3. Position the Hose Cutter
Position the hose cutter or utility knife at the marked cut location. Ensure that the blade is perpendicular to the hose.
4. Cut the Hose
Apply firm pressure and cut through the hose in a single, clean motion. Avoid sawing back and forth, as this can create a ragged cut.
5. Deburr the Edges
Use a sharp knife or deburring tool to remove any burrs or sharp edges from the cut ends of the hose. This will help prevent leaks and ensure a secure fit.
6. Clean the Hose Ends
Wipe the cut ends of the hose with a rag or towel to remove any debris or contaminants. This will help ensure a good seal when connecting the hose to fittings.
7. Lubricate the Fittings
Apply a thin layer of lubricant to the fittings that will be connected to the hose. This will help prevent leaks and make it easier to insert the hose.
