My mechanic lift my jeep cherokee limited 2000 and testing under car where coming voice.
Car was running abaut 20 minut .when mechanic driving from shop radiator i
n my Jeep EXPLODED.
What hapen?

 

Could be a multi of things: Maybe the fluid (coolant) was just too low and it overheated- Maybe the plastic pipe at the rad had a little crack and
the pressure was too much for it to stand- maybe it just died of old age. I 'd be inclined to go with my last "maybe" and just replace it
