BMW Alternator
The alternator works with the battery generate power for the car's electrical components like instrument panel and interior and exterior lights. It is typically found near the front of the engine and driven by the crankshaft, which converts the kinetic energy of the pistons' movements into electricity for the battery. A key component in the power train, a failing BMW alternator can kill your battery and leave your car without power to run.
BMW Alternator Parts Questions & Experts Answers
- Q: What should be done if the alternator is suspected to be faulty on BMW Z4?A:When if the alternator is believed to be questionable it should be removed from the automobile and brought to a motor-car electrician for testing. Majority of car electricians have brushes that they can sell and replace at an affordable price. However, find out how much it would cost to repair such before you make any step because it could be more economical to have a new or change over part instead.
- Q: How to remove and reinstall an alternator in non-turbo engine on BMW 335i?A:Switch ignition OFF. Disconnect negative (-) battery cable and cover battery terminal to keep cable from accidentally contacting terminal. Prior to disconnecting the battery, read the battery disconnection cautions in 001 Warnings and Cautions. Raise vehicle and support safely. Remove splash shield underneath engine compartment. Remove electric fan cowl and fan. Remove engine accessory belt. Mark direction of rotation on belt before removing. Remove intake air filter housing. Working at rear of alternator: Detach harness connector. Remove nut and detach alternator cable. Remove alternator mounting bolts and discard (aluminum bolts). Lift out alternator. With alternator on work bench: Remove idler pulley fastener plastic cover, if applicable. Remove idler pulley and transfer to new alternator. Reinstall alternator using new aluminum bolts. Reattach electrical harnesses. Reassemble front of engine. Remember to: Reinstall accessory belt using previously made direction-of rotation marks. Make sure accessory belt grooves engage pulleys correctly. After reconnecting battery, read Battery reconnection notes in this repair group.
- Q: What are the key features and benefits of the water-cooled alternator on BMW X5?A:The water-cooled alternator is an enclosed unit mounted on the engine-block, within the circuit of the water jacket and is, therefore, an engine-cooled unit. For these reasons, it is a 'brushless' sealed unit and cannot be serviced: the temperatures need to be kept constant to prolong the life of the unit. It also has the welcome side-effect of removing the alternator cooling fan, which results in even less noise. Also incorporated in this alternator is the load start reduction which reduces the time to start an engine particularly in cold climate because during starting the current load is limited to only 20 amps to minimize the alternator braking torque on the engine and as the starter engages full output is progressively developed.
