-pierce the hose with a screwdriver and try to pull it off the fitting

-use a pair of pliers to loosen the hose

Answer 1

To remove a stubbornly stuck heater core hose, a technician should pry behind the edge of the hose to loosen it.

Step-by-step explanation:

To remove a stubbornly stuck heater core hose, a technician should pry behind the edge of the hose to loosen it. Using a flathead screwdriver or a hose pick, the technician can apply leverage and gently work around the edges of the hose to break the seal and loosen it from the fitting. Once the hose is loose, it can be pulled off the fitting easily.

It is important not to cut the hose or pierce it as it can cause damage to the hose or the fitting. Using pliers to loosen the hose may not be effective and can also damage the hose or fitting, so it is not recommended.
