How do I replace alternator on Volkswagen Lupo?
The replacement procedure may vary for different car versions. It depends on the engine design, availability of an air-conditioner, and on what accessories are driven by the alternator belt. Replacement of the unit should be performed at a garage. Usually, removing it involves demounting of many other devices. In addition, in most cases, removal of the V-ribbed belt is required. After the procedure is completed, it is important to tighten the belt properly, which is difficult to do without special tools.
How do I tell that the alternator needs replacement on this model?
Noise, humming, cracking sounds coming from under the bonnet, especially when idling, indicate malfunctions of the unit. The ABS warning light may be activated on the dashboard. The battery charge indicator blinks constantly. The headlights become dim due to the voltage drop in the circuit, and often their light intensity changes with the engine rotation speed. Due to the fact that the battery is undercharged, the engine may fail to start after parking.
What causes malfunctions of the Volkswagen Lupo alternator ?
The design of the unit includes moving parts, which wear out in the course of time. These are bearings and brushes, which should be regularly replaced. Neglecting the replacement intervals can lead to breakdown of other elements. Many defects are caused by incorrect tension of the drive belt, and jamming of the belt pulleys. For instance, an overtightened belt increases the load on the bearing, alternator belt pulleys, and engine accessory pulleys. Poorly tightened fasteners can be loosened even more due to vibrations. This leads to damaging of the mounting holes. The terminals of the unit are prone to corrosion due to being exposed to moisture, dirt, and road salts.
Are there any other parts that should be replaced together with the alternator?
It is advisable also to replace the alternator belt, and, if necessary, the belt pulleys and tensioner.
What are the types of alternators for Volkswagen Lupo?
Various versions of this car are equipped with conventional alternators with a brush assembly. They can vary by the power output, fastening type, and dimensions. Be sure to select the unit compatible with your car in order to avoid problems during installation and use.
What safety precautions should be respected during installation of this component?
Never disconnect the battery or the voltage regulator when the engine is running. Never demount the alternator if the battery is connected. In addition, it is prohibited to perform diagnostics of car electrical/electronic equipment with the help of devices or control lamps powered from the mains electricity. Remember: if you mix up the polarity, the electric equipment of the vehicle may break down. All tools should be in good working order and clean.
