How to use a coolant hose removal tool

Loosen The Hose Clamps
Using a screwdriver or small socket, loosen the hose clamps. If the clamps are the spring type, use a pliers or a spring clamp removal tool. Slide the clamp away from the neck of the radiator.

Insert the Hose Removal Tool
Insert the hose removal tool between the hose and the fitting or radiator neck. Position the tool’s tip against the hose and apply gentle pressure to create separation.

Work Around the Hose
Continue to work around the circumference of the hose, gradually loosening it from the fitting. If the hose is particularly stubborn, you may need to reposition the tool or apply lubricant to aid in removal.

Tips to reinstalling a used or new coolant hose

Most DIYers twist and push a new replacement coolant hose on to the dry fitting. But if you’re installing new coolant hoses onto heater core tubes, pushing and twisting can break the solder joints and leave you with a leaking heater core; a HUGE and expensive repair job. To avoid damage and make the job much easier, simply dip your finger into fresh engine coolant and coat the inside the hose with engine coolant.

The coolant will provide enough lubrication to slide the hose right on, And, the coolant is 100% compatible with the rubber hose.

Do NOT use any petroleum based lubricant like grease or even WD-40. Those products can deteriorate the rubber.

Reinstall the spring clamp or work drive clamp.

WARNING: Carmakers use spring clamps when clamping a rubber hose to a plastic radiator neck. They do this to allow for the plastic radiator neck expansion and contraction. Worm drive clamps don’t expand in the same way as spring clamps. If you toss the spring clamp and tighten a worn drive clamp tightly, you can crack the radiator neck as it heats up. There’s a reason carmakers use spring clamps. Don’t second guess them by replacing with a worm drive clamp.
