Car belt broke and was driven for around 7 minutes before losing power. Gas peddle went limp, faint chugging noise, and the smell of maple syrup from a minor coolant leak from the radiator.
Car will not start, when attempting to start a whine is audible and the the serpentine belt turns; however, the car does not start. Oil seems fine, and there is no visible damage or disconnected wires. When plugging into the computer, no codes were reported. I believe a faulty alternator was the cause of the broken belt.
I also believe the car may have over heated. A pop was described (which I think was the belt breaking) and the car drive for about 7 minutes before the gas peddle went limp and the car was forced to stop. A small bit of coolant was spraying from the top of the radiator.
The car is a Scion TC 2008, it uses a timing chain and is an interference engine. I believe I was able to see the cam shaft spin through the oil cap. It seems unlikely that the timing belt broke as no horrific sounds were produced other than a minor chugging sound.
The car seems to lack spark or compression. It’s unlikely all the spark plus went out.
Here are my guesses:
Compression failure: maybe a blown head gasket.
Fuel injector or filter issue
Damaged coil packs
Maybe the timing chain
Any other guess would be appreciated. I’m by far a mechanic.
