I have a 04 camry le 2.4l 2az-fe. About a month ago I got into a small fender bender on my way to work to Lynnwood WA from Tacoma WA with low miles(less than 100,000), on freeway doing 20mph. Bumper was bent up but showed no leaks any where. And none of the lights on console lit up. I made it to work and back with no issues. Day after I went to oreiley's and they did odb2 test. Came back Ignition detonation knock sensor bank 1. I asked if it was relating to accident and they said no. When I left oreiley's check engine light came on. But when I got home the check light went off. Still no leak anywhere. But I could see ac condenser has a round pushed in Mark. But ac was still working fine., but I turned it off. Later I went to get money to put car in shop to get fixed.
Now, on the freeway (I was close to destination)it felt like I lost something. My gears wouldn't shift when I pressed down on pedal. Out of panic, I got to shoulders and cruised on on ramp. Still no light on dash lit up. I got stuck at a red light that didn't want to turn green. All of a sudden my car shuddered and my engine light n oil light lit up flickering back and forth. Car try dying so I pressed gas lightly while putting car in nuetral. It kept shuddering n flickering. The light turned green and my radiator blew making a grinding noise.
Car got towed. AC Condenser was punctured at bend and radiator blew where the fan seemed to have pressed on it. I replaced knock sensor, radiator and ac condenser. Car cranks high pitch sound but won't start. Mechanic did test said zero compression n that motor is blown. That can't be it, can it? Timing belt looks fine with tension, everything under intake manifold appears fine. The only faulty part other than radiator and ac condenser is the knock sensor. It was difficult to remove. It was melted over the nut. It was melted badly. Is this relating to accident or something else. What do I do?

 

Do you have the exact trouble code numbers?

Who did the repair work you or mechanic?

Did the temperature gauge ever go into the red zone during any drive?

Were you checking the coolant level in the coolant reservoir?

Any other plastic parts look damaged from heat?

The engine model also had a design issue with bad head bolt block threads. The result being a blown head gasket.

For the engine to be damaged it needed to run out of coolant or oil.
