Coolant Lines - with or without the TB bypass?

[Heisenberg]

The bypass hose is the one that doesn't go to the heater lines. If it's scrunched to the point it might be pinched off, can you remove it and shorten the ends a little?

Thinking yes. I will wait to see if Bweavy has a silicone version first.
Because that's just such a fun part of the engine to work in.
Said no one!
That's the least of my problems.
See my other post - "No boost"
That's what got me finding these coolant lines.

For a temporary fix, just put some tight fitting rubber caps on both throttle body coolant line nipples . If you want, place a dab of "The Right Stuff or Permatex "Ultra Black" on them first to guarantee no leaks & then either small stainless gear clamps, safety wire - tied with safety wire pliers or even tie wraps & be done....at least until your nipple(less) coolant line arrives & is installed.

I'd leave all the other hoses & S hoses intact as is.

I actually capped the manifold fitting and shoved a piece of 3/8 pipe w/ clamp - with a pipe cap on the end in the "S' hose temporarily.
Home Despot actually had the proper size brass cap for that fitting. It's SAE something. Not AN8 or 10. Can't recall the exact size..
That way - I didn't have to unwind the manifold fitting (again) - and re-install it later when I get the correct coolant lines.
I cleaned and painted the fitting so I didn't want to go buggering it up.

It also let me keep the "S" hose installed, so I could see if it interfered with my actuator line.
