Q: Car wont start even with jumper cables

asked by on May 02, 2017

Yesterday my truck wouldnt start and was making a rapid clicking noise. I was able to start it just fine with jumper cables, but this morning I couldn't get it to start at all. It wasnt making any clicking noises just seriously struggling to turn over even after letting the cables sit on it and charge for a solid 10+ minutes.

My car has 212000 miles.
My car has an automatic transmission.

It sounds like your battery is completly dead. This could have happened either because the battery is old and failed or because the alternator is not sufficiently charging the battery. This issue can be resolved in two different ways depending on the condition of the battery. If the battery is good, it can be charged up in order to test the alternator and determine if it is functional. If the alternator is not functional, the alternator should be replaced. The second way to resolve this issue is to replace the battery as opposed to charging it, and then check the alternator’s output. Consider YourMechanic as batteries and alternators can be tested and replaced at your home or office.

Hi there. Check all around the engine compartment for the coolant leak. Look at the radiator, over flow tank, radiator hoses, water pump, heater hoses, intake, core plugs (freeze plugs), and the heater core. One of those areas could be...
