6 hoses at t-stat

[dieselsmoke]

My t-stat housing has 6 hoses total. 1 in, 1 to pump, and 4 to manifolds and risers. After draining out the water which hoses do I pour antifreeze in. I know to fill the block through the big one but not sure about the 4 smaller ones. Thanks for any advice

Its a 2007 4.3 merc in a 185 sport

the 2 hoses that go to the bottom of the manifolds, remove them from the T housing and pour it in . about a 1/2 to 3/4 gallons in each one.
