Detachment and replacement of hoses of the cooling system

 Do not disconnect any hoses of a cooling path before full cooling of the engine.


1. If during performance of the checks listed in appropriate section of the Head Routine maintenance defects of hoses of the cooling system are revealed, they have to be replaced.
2. Empty the cooling system (see the Head Routine maintenance). If the cooling liquid filled in system is rather fresh, it is subject to a reuse and has to be merged in pure container.
3. Try to remember a route of laying of the hose which is subject to replacement. For a detachment of a hose weaken collars of its fastening on unions/branch pipes of the corresponding components. Shift collars on a hose, having completely released the sites of the last put on unions. Carefully remove a hose from the unions / branch pipes.
4. Remember that inlet and final branch pipes of a radiator are rather fragile elements - do not make excessive efforts at removal of hoses from them. For simplification of removal rotate a hose on the union. As a last resort, strongly "stuck" hose can be cut off from the union by a knife - despite connected about in such a way certain material inputs, nevertheless will be to replace a hose cheaper, than to get a new radiator.
5. At installation of a new hose at first put on it fixing collars, only after it pull a hose on unions/branch pipes of the corresponding components of a cooling path. If initially for fastening of hoses collars of the twisted type were used, they should be cut off and at installation to replace more reliable screw or worm. For simplification of landing of rigid hoses to unions it is necessary to moisten slightly the ends of the last with soap water, or to warm up the ends of a hose in warm water - do not use any oils as greasing.
6. Pull a hose the ends on unions and check correctness of its laying in a motive compartment. Place collars on the hose sites put on unions, having brought them for flaring of unions/branch pipes. Tighten coupling screws.
7. Fill the cooling system (see the Head Routine maintenance).
8. Start the engine, then attentively check system for existence of signs of leak of cooling liquid.
