This has been an ongoing issue for I don't know how long. I've taken it to several mechanics, with only 1 happening to find some issues.

One symptom I can bring up is that the radiator fan continues to run even with the car off being off for awhile. I didn't check to see if the fan was still running this morning, but prior events the fan was definitely running. I did notice my coolant was low when the engine is cold and I don't know how long it's been low, no overheating issues though. Also I've been getting weird clicking noises from the glove compartment, so not sure if that's part of the culprit

I took my car to the mechanic twice within a month. The first time, I told him about the fan and he said the motor was burned out, so he replaced the fan motor. 2 and a half weeks later, the battery is dead again. The 2nd time I take it to the same mechanic and told him that the fan was also running again. He said the alternator had a bad diode, so the alternator was replaced. Also the relays were replaced for the fan and I want to say the alternator was replaced the 1st time.

1 week later today, the car is dead again. I don't know where to go from here besides dropping the car off for a few days.

Anything I should really look into?

 

From my own experience when I ran low on coolant air was trapped in the system. Depending on engine RPMs it sounded like someone was throwing lil rocks at the firewall. You need to add coolant and bleed the system. With air in the system the fans don’t turn on/off when they should and you can overheat

 

Can low coolant really cause this though? My car hasn't been anywhere near overheating, the needle is always in the same spot, slightly above the middle line.

My coolant is low to be honest, like quite low. I'll ask around.

 

Find a new mechanic, at least one that listens to the customer...
