Engine Mechanical problem
2003 Cadillac CTS V8 Two Wheel Drive Automatic 65000 miles
After I replaced the alternator, the car wouldn't star it would make a clicking sound.I finally got it to turn over, a few times then back to clicking sound. I had it towed to a mechanic, he changed the starter and it still won't turn over. Possible problem engine frozen? It didn't lose oil, didn't heat up, I feel there is an electrical problem. He is my local mechanic not the Cadillac dealer. Is it possible that the engine is frozen?
