Under the influence of high temperatures in a motor compartment gradually there is a hardening and destruction of the rubber and plastic hoses ensuring functioning of various units of the engine and system of decrease in toxicity of exhaust gases. It is necessary to check periodically a condition of hoses, existence on them of cracks and hardening, weakening of connections, tightness violation.
The procedure for test of hoses of the cooling system is described in subsection 2.6.6.
Part of hoses fasten by means of collars. Check durability of an inhaling of collars as weakening of fastening leads to tightness violation. In those places in which collars are not provided, check reliability of consolidation of a hose on unions, loss of elasticity in such connections owing to swelling or hardening of hoses is not allowed, otherwise tightness of connection is broken.
Vacuum hoses
| PERFORMANCE ORDER |
| 1. Vacuum hoses can be distinguished on color, or on the color strips pasted on them. For various systems of the engine vacuum hoses with various thickness of walls, resistance to compression by the atmospheric pressure and thermal stability are used. When replacing track that new vacuum hoses in accuracy corresponded to the replaced. |
| 2. Often the hose can be checked only after removal from the car. If some hoses are removed, previously put tags on interfaced the union and hoses subsequently not to break their relative positioning. |
| 3. When checking a condition of vacuum hoses examine also plastic tees at the same time. Check existence on them of cracks, and also deformations of a hose in a prileganiye place to the tee union which can be a tightness cause of infringement. |
| 4. For check of leaks on a characteristic sound it is possible to use a piece of a vacuum hose with an internal diameter about 6,0 mm (1/4 inches). Having put the end of a hose to the checked place, listen through an opposite opening in a hose. Characteristic "hissing" will indicate leak existence. |
|
Fuel hoses
| PERFORMANCE ORDER |
| 1. Check a condition of rubber fuel hoses, existence on them of wear tracks or deterioration of appearance. Especially attentively check hoses in places of excesses and near connections, for example, in a junction with the fuel filter. |
| 2. When replacing the fuel highway on injector engines the new highway has to correspond in the accuracy applied in fuel system of engines of this type. |
| 3. For fastening of hoses of the fuel highway spring collars which lose elasticity over time are usually used. When dismantling connection such collar needs to be unbent then elasticity is lost finally. When replacing hoses always replace spring collars with collars with fastening by the screw. |
|
Metal tubes
| PERFORMANCE ORDER |
| 1. Metal tubes are usually used in the fuel highway for connection of the fuel pump with the fuel pressure regulator on a comb of nozzles. Check existence on tubes of the sdeformirovanny (twisted) sites and the small arising cracks. |
| 2. When replacing it is necessary to establish only seamless steel tubes. Tubes from copper or aluminum do not approach as do not maintain vibration loadings from the engine. |
| 3. Check a condition of metal tubes and unions of system of a hydraulic actuator of brakes in a junction with the main brake cylinder and the batcher (if it is provided), existence of cracks and the weakened connections is not allowed. At detection of any signs of leak of brake fluid immediately carefully check all contour of system of a hydraulic actuator of brakes. |
