Replacement of hoses of system of cooling

- If as a result of the check spent according to recommendations, resulted in the Head Current leaving and service, you have found out damages on any hose, it is necessary to replace it.
- Merge a liquid from cooling system (address to the Head Current leaving and service). If you are not going to fill in a new liquid in system, keep merged for the subsequent use.
- Flat-nose pliers compress short moustaches of regular collars (or ослабьте screws of collars of screw type — if are established by a screw-driver). Take collars aside. Accurately remove a hose from branch pipes. New hoses to remove much easier the old.
- If the hose does not act in film from a branch pipe, try повращать it. Do not damage branch pipes, trying to remove a hose. Breakage can lead to expensive repair. Keep in mind that radiator branch pipes fragile enough, therefore at removal from them of hoses do not put the big efforts. If the hose all the same does not act in film, cut off it, then cut the piece which has remained on a branch pipe lengthways and remove. Cost of a new hose is non-comparable to cost of a new radiator. Before to cut a hose, be convinced that can buy the new.
- At installation of a new hose at first put on it collars then establish a hose on branch pipes. If collars of coupling type were initially established, replace them with the screw. For simplification of installation of rigid hoses moisten internal surfaces of their ends with soap water or heat up in hot water (do not lower a hose in boiling water — it can be stratified).
- After hose installation on branch pipes check up correctness of its lining in an impellent compartment. Establish collars on the hose ends, having got them for развальцовку branch pipes, and tighten them.
- Fill cooling system (address to the Head Current leaving and service).
- Get the engine and make sure of absence of leaks of a cooling liquid from the served knot.
