2005 chevy impala was running hot stopped put water in it now it wont start back motor turns over but wont start battery dead

Question edited for clarity and a bit of punctuation.

Get underneath the Mazda and put put charger leads on the red terminal of the starter motor, and the negative on any good ground. BUT the keys are in the Impala so you have to start there!

Check your fuses ? Ses trivial but there was power in a few of those lines also reset computer by disconnecing batteries for 2 minute s

check for mud in the radiator and a slow turning fan motor

run fault codes and look for faulty sensors

Probably the ignition module under the three coil packs. It can be tested.

Believe it or not,230 is about where GM puts it. Claim the engine pollutes less at hot temps.
Fans should run with the AC on tho,mine runs cooler with the AC on .

sounds like you have a bad actuator motor that make temp go hot to cold

Turn the key to "on" and let the light flash. It should stop flashing after about ten to twenty minutes. Once the light is on steady, turn it off, then start the car. I usually put another battery on jumper cables attached to the cars battery so it does not run down and die before the system re-arms.

If the battery has gone dead, it could cause the security system to go into full lock-up mode. If it has locked up the accessories will work after the battery is charged back up , but the power to the starter will be cut off and it wont turn over. You need to do the 30 minute learn procedure. A GM dealer will print it out for you and you can do it yourself. It's very simple if you follow the procedure exact. hope this helps and good luck.

search web for TSB's for this car, there was a recall for this!
