[Tigers] Radiator catch can

[Ronak, T. (Timothy)]

Cooling cars does require adding a couple of ‘modern’ improvements ...
1 A catch can that is open to the environment but has an airtight piece of tubing (sealed at the catch can nipple and always submerged in the extra reservoir) This permits coolant to expand and be stored/contained and then when the car cools it will suck back into the cooling system. This is how a modern overflow works.
2 The radiator needs to be sealed around the perimeter in the opening it sits in and even a lower “air dam” that prevent air recirculating under the radiator and back around through the front. 
3 Ensure ALL AIR IS EXTRACTED from the cooling system and really the only way to do this is to use a vacuum generating device like an “Air Lift” device that physically removes all of the air pockets in the system ... I would do this first through the radiator cap opening and then after sealing the system back up do it through the expansion tank overflow nipple as the car warms.

My 2 cents
