just a quick question.. I replaced my TB today with a SOS one.. In the process, I had to remove the 2 coolant lines going to the TB.. does this require a bleed of the system? I want to say no, because I don't believe any air was introduced into the system, but am unsure.

Any thoughts?

You should be fine. Go out and drive it and make sure your temps are stable. You wouldn't have introduced much air during the swap.

You will be ok but if you're super anal retentive bleed it anyhow not like it's hard

Remove radiator cap
Idle car up to full temp (rad fan comes on x2)
Make sure the overflow tank stays full
Put cap back on
