I am stuck-on the side of the highway right now here's what happened.-I was driving 115kph and my battery warning light came on I watched the voltage drop to 11.8 then the temp jumped from 94c to 135c.-I immediately shut the truck off and pulled it over to the side of the road. Steam pouring from under the hood. I lifted the hood and my coolant lid is popped off and splattered up on the hood and a huge puddle of it under the truck.-Also my power steering is gone.-What happened guys?

 

your truck had a hard case of the mondays.

i honestly have no clue.

 

Now that the steam has cleared I can see its a broken belt

 

Thats what i was going to say, hopefully overheating didnt cause any damage

 

Yeah that's what I am worried about.
How hot would you say is too hot or the tempature where damage is likely to occur?

 

Im not really sure, I know ive had mine pretty close to the H on the gauge a few times but never where it blew the cap off.

 

this is my first thought. my second is go get a new rad cap because that sucker should never blow off. it will be rated for the max safe system operating pressure, anything above that pressure and the cap should release the excess pressure into the atmosphere... making it not possible for the cap to come off. most i have seen are between 5-15psi
