Please dont take the piss this is a serious question, how long do you reckon a car could run without coolant in?

My drive has a pretty big slope for the bottom half of it with the top half level and the garage at the end. I want to drop the coolant out the missus’ clio at the bottom of the drive but I’ve got a few things I need to do to it so need it up near the garage really. I was thinking of dropping the coolant out, starting it and driving up the slope to the garage. If I was to do it the car would only be running for probably 20-30 seconds, would I get away without damaging anything or is this a completely cock idea ?

running it for that amount should be fine but why dont you just drop the coolant when its in the garage ???

 

yeah thatll be fine mate, just leave it to get cold before you drop the coolant and drive it.
