water pump replaced....
ok so i took my truck in cause it was loosing coolant under the motor. so they replaced the water pump. today i picked it up and pulled into the gas station 15 miles from the dealership. so i pulled out and drove about 100 yards to a red stop light. when i went to take off it feel on its face spitting and sputtering white smoke. so i finally got it off to the side and put it in park. it was almost silent so i nailed the gas peddle and it spit and sputtered for about 15 seconds and poured white smoke, after that it drove and ran fine the rest of the way home. anyone have any idea what could be wrong? also they scratched the he!! out of my front bumper from standing on it while working on the truck. what do you think i should do about it? thanks for the help guys
