My custom made coolant inlet pipe and associated simplified cooling line system.
So what I did was remove the stock coolant inlet pipe going into the block. I then welded the Tee piece that's normally attached with a hose clamp to it. Then I chopped up that long pipe that normally bolts to the intake manifold and welded more fittings to the new pipe. Then I sand blasted it, prepped it, and zinc coated it. The lines are as follows;
-Large opening is for the lower radiator hose.
-Pipe pointing upwards with the black silicone 90° is for the thermostat closed bypass loop.
-Pipe closest to screen pointing towards the left is the coolant return for the heater core.
-Next pipe back towards the block with the straight black silicone hose is the coolant return for the oil cooler.
-Last line you can't really see, but that braided SS line connects to it. That is the coolant return from the turbo.
