System of cooling of the engine

Detachment and replacement of hoses of system of cooling

Do not disconnect any hoses охладительного a path before full cooling of the engine - "the Safety measure" subsection in the previous Section see.

If during performance of the checks listed in corresponding section of the Head Routine maintenance, defects of hoses of system of cooling are revealed, they should be replaced.

 PERFORMANCE ORDER

  1. Empty cooling system (Routine maintenance see the Head). If the cooling liquid filled in system is enough fresh, it is subject to a reuse and should be merged in pure container.
  2. Try to remember a route of a lining of a hose subject to replacement. For a hose detachment ослабьте collars of its fastening on unions / branch pipes of corresponding components. Shift collars on a hose, completely having released посаженые on unions sites of the last. Cautiously remove a hose from the unions / of branch pipes.
  3. Remember that inlet and final branch pipes of a radiator are fragile enough elements - do not make excessive efforts at снимании from them hoses. For simplification of removal повращайте a hose on the union. As a last resort, strongly "become attached" hose can be cut off from the union a knife - despite connected with in such a way certain material inputs, nevertheless will replace more cheaply a hose, than to get a new radiator.
  4. At installation of a new hose at first put on it fixing collars, only after that pull a hose on unions / branch pipes of corresponding components охладительного a path. If it is primary for fastening of hoses collars of braided type have been used, they should be cut off and at installation to replace more reliable screw or worm. For simplification of landing of rigid hoses on unions it is necessary to moisten slightly the ends of the last with soap water, or to warm up in warm water the hose ends - do not use as greasing any oils.
  5. Pull a hose the ends on unions and check up correctness of its lining in an impellent compartment. Place collars on the sites of a hose planted on unions, having got them for развальцовку unions / of branch pipes. Tighten coupling screws.
  6. Fill cooling system (Routine maintenance see the Head).
  7. Start the engine, then attentively check up system on presence of signs of leaks of a cooling liquid.
