Q: Dead battery. Jumping for every start. Replaced radiator flange and now car started no prob

asked by on

Could a bad radiator flange affect the battery? Battery is need jump for every start. Replaced radiator flange and started without jump

My car has 175000 miles.
My car has an automatic transmission.

The radiator is not related to vehicle starting. The only relevant possibility would be if you replaced a sheet metal component that holds the radiator that may have also had a vehicle ground wire attached to it. If the vehicle ground is poor that can cause all kinds of electrical problems, including hard starting. Driving a car with a possibly bad battery is hard on the car’s electrical system, including the charging system and the sensitive electronics in the car. You might want to consider requesting a battery inspection/replacement in order to avoid problems. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you to get the best possible results.
