If the battery is slowly going down, it's probably the charging system. Batteries are only storage devices, and only store electrical energy that is created elsewhere, in this case, by the charging system. If your charging system is getting weak it might not be able to keep up with the radiator fan.
Have you checked the alternator?
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight.
Get your charging system checked out as it sounds like your alternator is going bad or the battery is shot.
you have a ground somewhere
Something is discharging the battery when it is not running. Have the electrical system checked.
The battery light indicates the system is not charging. Have the charging system checked. If the alternator is not charging, the engine will quit running and leave you stranded.
It may need replacing or it can be the alternator is overcharging the battery. Have the charging system checked out. The alternator should output from 13.5 to 15.5 volts with the engine running at idle.
Sounds like the alternator isn't working at all. Have it checked. Good Luck!!
Why are you disconnecting the battery with the engine running? Never mind, you've probably already figured this out by now, but there's a good chance your alternator is fried and your spark plugs are running on battery power. Get your alternator checked out. New ones aren't that expensive (approx. $50) and can be changed by anyone handy with tools.
The radiator cooling fan will run to cool the radiator to below the fan turn on temperature. You may want to have your cooling system checked if it happens regularly as your Buick may be running hotter than normal when driving.
Check the battery with a vom meter while the engine is running. It should read about 14.5 volts and if so the alternator is working, than have the battery checked Now if the meter does not read 14.5 volts, have the battery, and the alternator checked. If they both check out okay, the problem is in the battery or the alternator circuit on the vehicle.
the battery might be running down have it checked or check the hood yourself
I would suspect a bad alternator and battery, have them both checked at the parts store. A car with a fully charged battery and a bad alternator will run until the battery is drained and then quit.
The radiator fan should not run after the key is shut off. The normal cause is a failed radiator fan relay.
have the alternator and the battery checked
probably needs a fuse either underhood fuse or under dash fuse if not either you will have to bypass directly to the battery
I checked my owner's manual - it listed radiator capacity at 6L.
Your putting a charge on the battery when its running.
Do you mean they dim when you push on the gas? If yes then try having the alternator and/or battery checked. Normally the battery should be between 13 and 14.5 volts when running.
I'd start with the thermostat. Make certain that you have plenty of coolant and that the radiator isn't blocked. After you've checked all that... we'll talk.
I think the person means the heater blower motor and not a radiator fan motor
Could be a faulty thermostat switch in the radiator !!
Your heads are probably warped from overheating. have them checked out by a machine shop. Sometimes they can machine them back to flat, but you might have to replace them.
Perhaps starter is weak. Have it tested for load and drag
Remove the battery, radiator support brackets, battery air filter housing, and air filter hose. Raise the vehicle, and drain radiator. disconnect the transmission cooler lines, and the radiator fan. Unbolt the radiator an remove. Reverse the process to install.
