Fuel
Fuel is the great villain of the car that has been stopped for a long time. Gasoline dries and can trigger various problems in the pump, valves, injectors and in all the piping through which the liquid passes. Another danger is starting the car dry and scratching the engine components. In addition, according to Erwin, gasoline can form sediments that do not dissolve and end up clogging the pipes.
Cautions:
To preserve the engine, start and first run without compression. This helps to lubricate the parts and avoids scratches. The ideal if you are going to leave the car still is to start the engine once a week for 20 to 30 minutes.
Fluids:
Fluid aging can also damage various components of the car that has been stopped for a long time. Roberto explains that in the brakes, for example, the oil worn out by locking the calipers that act in braking the wheels. The engine cooling system is another component that can suffer corrosion due to the aging of the coolant.
The most sensitive parts are also those that have contact with liquid, such as plastic hoses and rubber parts. Oh, and for those who have an automatic car, it's not good to let the gearbox fluid run out.
Cautions:
If you are going to leave the car stationary for a long time, it is possible to do work in specialized workshops to exhaust all fluids and leave the car dry. It works as a preparation for the vehicle to "hibernate". Then, when the time comes to turn the key again, just add the fluids normally.
