so my friend and i were driving yesterday when his car started overheating. the coolant level was filled and when we pulled over, there was steam coming from the coolant tank. it was so hot that the tank itself was boiling.
we were able to get the car back to his house safely but now the car is having a really hard time starting. it will start up but it won't idle. what do you think the problem could be? do you think he cracked the block? also, it won't idle correctly.

thanks

 

is it smoking alot??.. might of blew the headgasket from overheating

 

might be. should he just replace the head-gasket?

 

DO A COMPERSION TEST ON THE MOTOR,DID YOU BLEED YOUR COOLANT SYSTEM AGAIN MAKE SURE THERE NO AIR IN IT WHICH WHOULD TRIGGER THE IAC SENSOR AND MAKE YOUR CAR IDLE BAD ALSO.BUT IT MOST LIKELY ACTING UP SINCE YOU OVERHEATED AND POSSIBALY BLEW THE HEAD GASKET IF SO HOP YOU AINT WARP THE HEAD AT THE SAME TIME

 

how much is it going to cost to fix all this?
