[DeTomaso] cooling tube routing question

[davidabell at att.net]

John,

The port on the block is the hot water outlet that goes to the heater core.  Without actually seeing your water pump, I'd guess that those ports are similar to my Stewart Components water pump and are both located on the suction side of the pump.  So yes, you'd need to plug off one of them.
