Where is the radiator drain plug on a 71 impala?

Question

I want to change my fluids and need to know where the drain plug is located. Thank you.

Answer 1

generally drain plugs are located opposite of lower hose.

Answer 2

Doesnt look like a drain plug to me. I would guess that the tanks on the radiator are plastic and there should be a valve with a plastic handle somewheres on the bottom of the tank. To my knowledge radiators have always used valves and not plugs to drain the radiator. Less chance of getting scalded if you have a valve that can be opened gradually.

Answer 3

Occasionally the actual drain plug is a plastic twist handle located on the side of the drivers side lower radiator expansion tank. Yours, if the radiator is origional, will be a metal twist T handle because the origional Harrison Radiators had brass / copper tanks. I will admit that Harrison had none at times, which means you'll need to drop the lower radiator hose.

Answer 4

If there's not one right on the bottom of the radiatior, just remove the lower hose to drain it. Lot of cars don't have a plug. Good time to change the hoses too, if they're old.

Answer 5

Hello,

On my 71 monte carlo it was on the passenger side of the radiator, it was a METAL part that had flat handles like a wing-nut. But BE CAREFUL, Your tendency woud be to UNSCREW IT but in this case the drain plug would have to be SCREWED IN to open it. i ruined the original that way.
Hope it helps

Answer 6

Don't believe it has one. You either need to install some flushing-T's in your system, or simply remove the bottom clamp from the rad.

Answer 7

Most are on the driver's side at the bottom.
