Stages of work
Drain the coolant into a container.
Loosen the hose clamps and remove the hoses.
Loosen tightly seated hose ends with a screwdriver. Insert the screwdriver between the hose and the fitting and then carefully pry away from each connected fitting.
Install new hoses with Vaseline and push them far enough onto the fittings so that they cannot slip off while driving.
After removing the radiator hoses or fuel hoses, you should replace the clamping hose clamps 1 and 2 with screw hose clamps 3, which do not cut into the hose so deeply and their clamping effect is much better dosed and distributed.
