Sequence of work
1. Check the tightness of the hoses on the radiator, engine and interior heater radiator.
2. Check the condition of the hoses by bending them. Replace hard, brittle or cracked hoses.
3. Check the tightness of the hose connection on the suction pipes.
4. Check up, whether collars are well tightened. If the clamps are loose, fluid may leak and the fasteners will corrode. Replace rusty clamps.
