This is my coolant layout - the 2" dia alum tube next to
smaller blue tube has my Stand Radiator cap. Coolant pressure sensor is
shown about 2/3 down the tube. A clear plastic hose comes out of the
radiator cap overflow tube and is plumbed to the bottom of the second 2" dia
aluminum tube which acts as my over flow can. Once the coolant system
cools down any fluid in the overflow can is drawn back through the radiator cap
into the engine block. The 2" dia overflow can is a bit on the small size
- roughly a pint. A quart would be better. I ocassionally lose a
small amount of coolant - particularly on hot days.
