!over heating issue!
i recently replaced the head gasket,cylinder and themostat because it cracked and over heated. since than, a week later it over heated again. took it back to the same place (midas) they said a valve was not tighten and that moisture ended up freexing the valve so the antifreeze was stuck and wasnt circulating.. well a month later, while idling my temp. gadge tends to rise above where its susposed to be..when i drive it moves down to where it should be. Can anyone tell me what it could be?? i dont want to be stranded in the bitter cold!
