I had the water pump go on my old truck while on the highway in. Started to smell something funny and it was getting dark. Then I saw people behind me getting FAR away from me.. From their headlights I could see the steam pouring out behind my truck - it looked like it was on fire. Pulled over, saw liquid pouring out, called the mechanic. He said "oh there's a

load of coolant in these things, just drive it in and right into the shop". As I drove through the yard I had a good tail. Driver's asked me if my truck was on fire. Yeah, buddy, I'm driving a truck that's on fire.
