if it was a fire under the hood, file a comprehensive claim on your auto insurance. Other than that, you are probably outta luck......red
I would guess a belt. Example: Your air conditioning compressor bearing/alternator bearing failed and the rotor won’t rotate . Your belt smoked. Or timing belt. Just a guess.
I had a Buick catch fire around 30 miles from home. As luck would have it, I had a fire extinguisher with me for the first time ever.
I discovered the auto transmission was leaking fluid onto the exhaust.
I had the transmission rebuilt and after several days it came to me that my auto insurance might pay for it. I contacted my agent and sure enough, they paid for it.
I also first thought of the serpentine belt which someone else mentioned.
