Q: car runs hot and sometimes have to shake battery to start sometimes

asked by on October 27, 2016

I have brought an new battery, water pump and a used alternator and a new thermostat. My car runs hot after driving for maybe 10 mins, it doest shoot water out or anything it'll just go back down for a little while then back up again. i do sometimes smell like a metal smell when it gets hot. With the battery sometimes it just cuts off in the middle of the road i have to get out and shake the battery. I did get the black battery post changed but not the red one. the red one is the really thin post and the black one i brought is really thick. could it be the post on the battery or is it the wires to the battery or what?
My car has an automatic transmission.
