[DeTomaso] coolant bypass

If that is the case? Why not just remove the thermostat all together and remove the brass ring under it?

It is just the size of the passage through the thermostat. Add 2 and you

the hole is the water passes trough. With long narrow tubes in a Pantera
anything to keep the flow going.
