bought new battery 2 months ago now that it finally is getting cold car won't start ,it just makes a grinding sound as if starter and fly wheel are battling.so i am thinking i need new bendix on starter until father comes over and gives me a jump with his f150 and car starts up fine did this 3 days in a row.battery has been checked and is fine,also it has 590 cca (is this enough?)so should i get a battery upgrade or concentrate on starter and flywheel.
