Yep thats the little sucker motor overheats so today I have flushed block, radiator, checked impellor in pump all looks good so only thing I can think of is water is taking path of least resistance thru the pipe I have now capped off the 2 holes & drilled a 1/8" hole in thermostat. I have also fabricated block off panels for top & bottom of radiator. I am also going to fit a 7 blade fan in place of the 5 blade on it now.I also found a blob of solder was under seat for radiator cap where the overflow pipe has been previously repaired so coolant pumps straight out as soon as there is any expansion
