Hey guys. New here, just got a 2016 Altima s has 75k miles. Started smoking and heard a pop came home to see the radiator popped. Replaced it hooked in all the hose and cables. I have a charger on the battery for about two days now. Still won’t turn over. Has battery, does something when trying to start car but won’t turn over. Please PLEASE HELLP.

When the radiator exploded it may have damaged something in the charging system. A properly working charging system puts out about 13.2 to 15.0 volts, A battery should have a static charge of 12.3-12.8 volts when the engine is shut off. If a battery is not good, the charging system may not be able to charge properly. If a vehicle is not charging properly and the battery is good, the first thing to do is to turn the ignition switch to the "ON" position without starting the engine and make sure the charging system warning light is operating. If the bulb is burnt out or the fuse is blown, the charging system will not charge. If the bulb is OK but still does not illuminate, the circuit must be tested. If the warning lamp does illuminate, then the next thing to check is to make sure the circuit between the battery positive post, or fusible link, to the connection in back of the alternator is good. On Nissans, this will be a thick (approx. 10 gauge) wire to the "BAT" post on the back of the alternator. It's not uncommon for this wire to get corroded and burn up, creating resistance in the circuit or was damaged when the radiator exploded. So, before assuming an alternator is bad, make sure this circuit is good and battery voltage is getting to the alternator. It's also important to make sure the alternator belt is tight and not slipping and the battery connections are clean and tight.
