When all installation work, in particular in the engine compartment, because of the tight layout, consider the following.
Motorways of all kinds (such as fuel, hydraulic absorber, activated carbon, cooling systems, circuit conditioning systems, brake lines, vacuum hoses) and electrical wiring must be routed as they were originally laid.
Provide space for all moving or hot components.
When the engine is warm the cooling system is under pressure. If necessary, the repair work is necessary to relieve the pressure.
Hose connections are secured with spring clips. When repairing only use spring clamps.
For the installation of spring clamps is recommended to use pliers for spring clamps or pliers for hose clamps.
When installing, route the water hoses on pulling them. Make sure that they do not touch other components (observe markings on the fitting and the hose of the radiator).
