This is the shocking moment a mechanic was engulfed in flames when a car engine exploded during repairs.

The owner of the sedan asked her boyfriend and younger brother to check the vehicle, which suddenly burst into fire while they were working on the four-wheeler in Phitsanulok, Thailand.

CCTV footage shows flames shooting straight toward the mechanics, with one of them noticing his hand was on fire on November 8.

Both ran to safety as the engine bay continued to blaze.

They quickly grabbed a hose to douse the flames, and after putting out the fire, the man wearing shorts poured water over his face and arms, which had been scorched in the blast.

Local media reported that the men sustained minor burn injuries with blisters.
