alright guys my truck started running hot the other day just keeps getting hotter if i stay in it, if i stop it will cool back down but just as soon as i get back on the road again it will heat back up pretty quick.i changed the thermostat friday and it is still doing the same.seems to be circulating when i look in the resivoir.but here is something else when i shut the truck off and the water fills up the resivor it isnt going back down to the full cool line after it sits for a while.let it sit all night and it was full almost to the cap.after i started it up this morning and drove it to town the coolant level went down to full cold mark but when i shut it off it filled back up the resivor again,any thoughts?when i changed the thermostat i let it run for about 30 mins with the cap off so that it would bleed out the air.also here is something else when i drained the coolant from the petcock drain only about a 1-1/2 gallons of fluid came out with the resivoir cap off,thought that was a little weird the when i broke the seal on the tstat housing the coolant came on out.HELP please.thanks
