Always reinstall body heat shields. Observe the recommended tightening torques for threaded connections. Wear protective clothing and goggles when carrying out repairs.
The car body is welded, all-metal, bearing structure. The bottom, sides and roof are welded together. Hood, trunk lid (tailgate), doors and front fenders are bolted on and can be easily replaced.
The body is a three- or five-door hatchback, for some markets a station wagon model is produced.
To enhance the carrying capacity of the body, a subframe is used to mount the power unit, suspension and steering mechanism.
The front wings of all models are made of a polymer that can withstand a frontal impact without visible damage at speeds up to 16 km/h.
All new cars have effective protection of the body and bottom against corrosion. Various technologies are used for this, such as galvanization, zinc phosphate coating and priming. An anti-gravel coating is applied to the front of the hood. For the treatment of box-shaped and hidden cavities, wax formulations are used.
There are many plastic elements in the body structure - bumpers, wheel mudguards, radiator grille, etc.
The gaps between the body parts must be the same along the entire length. When installing new removable elements, it is very important to comply with the clearances and tolerances established by Renault, otherwise the installed elements may jam or the noise level in the body may increase sharply. In addition, the aesthetic standards for the car are violated.
Body gaps
Shown on the example of Renault Clio
Figure 9.1. Gap control zones between the body and removable body elements
Figure 9.1 shows the areas of the vehicle for which controlled gaps are set between the body and its removable elements, and Figures 9.2a and 9.2b show the clearance values.
