Sequence of work
1. Drain the coolant.
2. Loosen the clamps, remove the hose.
Pic. 4.52. Clamps: 1, 2 - spring clamps; 3 - screw clamp (recommended)
3. If there is a non-removable bracket on the clamp, break it and replace it with a clamp (pic. 4.52).
4. Bend the stuck ends of the hoses with a screwdriver. Insert a screwdriver between the hose and fitting and carefully remove the hose in a circular motion.
5. Push the hose onto the fitting as far as it will go to prevent it from being torn off.
6. Do not tighten the screw clamps with maximum force, as the threaded scars may be deformed and the clamp will lose crimping power.
7. Fill in coolant.
