dibarlaw Posted September 19, 2011 Share Posted September 19, 2011 I have searched all my old Torque Tube mags and my shop manual. The shop manual states that the block drain is located at the rear most cylinder. I have felt all over the block and have found nothing that low for a drain out. Now the rear freeze plug is leaking. I thought I drained everything 20 years ago. But I guess not. Since I am starting to work on it again I need to pull the radiator and have it redone. It looked perfect the last time I ran the engine(1991) But time marches on. Link to comment Share on other sites More sharing options...
danhar1960 Posted September 19, 2011 Share Posted September 19, 2011 It's more than likely someone at some point in time has removed the T-type cock and put a plug in to it. On my '39, it's about 4" behind the distributer going toward the firewall and at the same level. I would imagine it would be the same for a '37.

38Buick 80C Posted September 19, 2011 Share Posted September 19, 2011 here is the drain cock on my '38 320cid engine. it is located about cylinder six on the passenger side of the engine. I also have a drain cock at the bottom of the radiator. Not sure if this helps you being a different year and engine. Link to comment Share on other sites More sharing options...
