System of cooling of the engine

Detachment and replacement of hoses of system of cooling

Do not disconnect any hoses of an okhladitelny path before complete cooling of the engine - see the subsection "Precautionary measure" in the previous Section.

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

 PERFORMANCE ORDER

  1. Empty cooling system (see. Head Routine maintenance). If the cooling liquid filled in system is rather fresh, it is subject to a reuse and should be merged in pure container.
  2. Try to remember a route of laying of a hose 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 planted on unions. Carefully remove a hose from the unions / branch pipes.
  3. Remember that inlet and final branch pipes of a radiator are rather fragile elements - do not make excessive efforts at a snimaniye of hoses from them. 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 by a knife - despite connected about in such a way certain material inputs, nevertheless will cheaper replace a hose, than to get a new radiator.
  4. At installation of a new hose at first put on it fixing collars, after it pull a hose on unions / branch pipes of the corresponding components of an okhladitelny path. If initially for fastening of hoses collars of braided 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 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 correctness of its laying in an impellent compartment. Place collars on the sites of a hose planted on unions, having got them for a razvaltsovka of unions / branch pipes. Tighten coupling screws.
  6. Fill cooling system (see. Head Routine maintenance).
  7. Start the engine, then attentively check system on existence of signs of leakages of cooling liquid.
