The check engine light is a notification that the computer has detected a problem. You need to connect a diagnostic scanner to the vehicle and see what the code is saying.
Changing the battery will not make the light come on. The computer will automatically recalibrate itself after a few driving cycles. If the check engine light is on, you have a problem with the emissions system. Have the computer scanned with an OBD2 scan tool.
No, changing the battery has no effect on how hot or cold the engine runs. The battery has one purpose and that is to store electricity that is used to start the engine and run the electronics on the vehicle. The alternator keeps the battery fully charged.
(no it uses the energy from the car battery not the energy made by the engine)Yes it does increase consumption because the battery has to be recharged by the power of the engine driving the alternator or the dynamo
If the engine is running, then no. The alternator constantly keeps the battery charged.
YES always disconnect the negative cable from the battery first then just be careful to hook up the negative cable to the battery as the last step
Yes it will
your Alternator
You do not have to reset anything. but you should have the battery disconnected. and once you reconnect the battery it will reset your computer.
Yes it will reset after a set amount of driving cycles if that repaired the problem. Or you can remove the negative battery cable for 5 minutes to reset the light.
battery is low charge. Take it for a long drive, to take the load off the engine from the alternator charging it.
Both. It has motors driving the cooling fan and blower for the heater and A/C. It has an engine driving the wheels and propelling the vehicle down the road.
If the alternator fails, it is no longer keeping the battery charged and your engine is running on nothing but battery power. Once the battery runs down, your engine will no longer run.
