[Fot] TR4 cooling

[Bill Babcock]

Peyote has a line that goes from the freeze plug in  the back of the  
engine to the suction of the water pump. It's not a small line, It's  
AN-8 I think. the freeze plug has been replaced with a brass disk  
that's held in place by a bracket with three bolts. I'd send you a  
picture, but I'm in Maui until april.

As to whether or not it works, I can't say for sure. I still tend to  
stick #4 cylinder before anything else, but my engines last a long time.
