Yesterday I put a citric acid flush in my 83 CD and drove it about 15 miles, when I got back I went into the garage for a screw driver and when I came back it was pouring water out of the area of the waterpump. I shut it down, refilled the rad. and started it back up, no leak. I drove it with the brake on to heat it up but no leak. I jacked it up and looked all over the front of the engine and the only thing I found was a bit of steam that seemed to be from behind the harmonic balancer. Monday I will have it pressure checked, but are there any other ideas?
