Coolant Feed and Return Hose

calvintibia001

So I am welding up my Manifold for my turbo, so I was trying to sort out where the coolant hoses go.

Here I named the 3 coolant hoses A, B, C. I know C is for the Lower Rad for Coolant Return.

The Hoses in the question is A and B. I know A is a Heater core thing that goes behind the water pump (A2).
But does A1 plug into B3 like this ?

So B2 is for the Coolant Feed for the Turbo, but where does B1 goes ?

Thanks Heaps.

No. B goes from the header tank to the radiator and the hose off it goes to the turbo top feed. Bottom hose is the return for the turbo. Unsure why you have "A" as its for the heater.

Hmmm, then A have nothing to do with the Coolant Feed ?

No different to what's on the car no. I took pics last night of the other two for you though.

The reason why I thought it was different is, when LT gave me all the stuff, the heater hose was in there as well, thats why I thought it was Turbo related

Part A has the extra T at the bend to feed a watercooled oil cooler. If your not running the watercooled oil cooler you can stick with the standard pipe that doesnt have the T in it.

Ahhhhh, that explains why, I am going for an aftermarket oil cooler and oil filter relocation kit, so i dont need that bit
