Plumbing for cooling system

[Pete Clayton]

I'm trying to get my head round where everything will connect to on the cooling system and could do with some help

Right so far I figure, largest outlet on the thermostat housing to the top hose on radiator. Water pump to bottom hose of rad. The small outlet on the top of the thermostat housing to the top pipe on header tank?

I then have remaining the other outlet on themostat housing which would presumably go to the heater matrix but I am not going to run a heater. The small outlet on the side of the rad, the bottom outlet on header tank and this pipe on the inlet side which I presume is to do with cold start.

Help and tips appreciated as usual :)

Thanks Paul, that looks pretty much what I have found out with the only addition being the inlet one which also feeds off the bottom hose

Thats the one that lets a small amount of coolant circulate through the block while the thermostat is closed, preventing hot spots around the cylinders.
