Hey guys,

I'm swapping an LS1 into my BMW and I'm not very familiar with this engine, so could you do me a favor and identify these parts?

1. These two plugs are supposed to go into the throttle body I think, but there's nowhere to put them. Also, what should go in that hole on top of the throttle body?



2. The next two pictures are of the same hose. The first is of this green **** on the hose:



And this is the end of the hose:



3. This hose comes out of the water pump assembly (you can see where it comes from in the background.



4. This hose comes off the back of the engine.



Here's where it originates:



TIA guys, I really appreciate it!

1. One goes to the IAT sensor that would be in the air lid and the other goes to the MAF sensor between the air lid and throttle body. The hole is for the EGR and it can be plugged with a expandable freeze plug.

2. That goes to the return line that heads back to the gas tank

3. That line comes from the coolant crossover tube that is under the intake and throttle body then goes to the radiator

4. This one goes to the brake booster so you have vacuum for the brakes.


Now if you use all of these on your swap I couldn't tell ya cause I don't know how you have it set up

Thanks for the quick reply!

Question about the coolant crossover tube. Is that coolant that needs to be routed to the radiator (ie it's coming from the engine block), or does it need to come from the cool side of the radiator?
