Van was driven at approximately 7:50pm a short distance. After parking vehicle, 10 minutes later the alarm went off. Upon disarming the alarm, the entire engine was engulfed in flames. Van is maintained regularly, no check engine light indicating any issues with vehicle. Entire engine caught fire. Fire dept extinguished fire. No comprehensive insurance so no inspection to cause of actual fire. Neighbors Ring camera shows alarm going off and as soon as it was disarmed, engine completely engulfed in flames. This video was sent to fire dept for their report. Vehicle still sitting where it caught fire, in front of my residence. I have yet to get it towed or inspected.
