Default Is the coolant line from the radiator to the TB line really needed?

Many of us do TB coolant bypasses, but is that coolant line really needed? What would happen if I were to just plug up each end and ditch the line all together?

No, that's one of the "free" mods on our cars. It's only a concern if you're concerned about the TB getting "iced" from moist, cold air.

I'm not talking about bypassing the TB... but removing the coolant line all together and plugging up the connection on the radiator and that rail tha goes between the heads.

I'm sure you could and it won't hurt a thing but I wouldn't! I'd just spend the $.50 I did at True Value, pick up a plastic connector and bypass it. Simple as that. Everything is still operational, it just doesn't flow through the TB.

What do you wish to accomplish by plugging it at the radiator?

The line comes off the coolant line that goes inbetween the heads underneat the intake.

I ask this because I'm doing an engine swap, putting an LS1 into a 97 f-body and wonder if I just don't bother with it, will cooling be affected.

That line is the air bleed from the engine to the radiator. If you remove it, the engine might not purge the air after the coolant refill.

Those are basically steam lines. I would not block them altogather

You can, however, purchase the LS6 coolant pipe. That illiminates the rear coolant lines. That way, no coolant lines will be under the intake. You will need the plugs to cap off the holes in the rear cyl heads that the original coolant lines hooked to. Still will retain the front coolant lines to each head that join and go to the top of the radiator.

Ron,

What's the difference between the LS6 coolant pipe and the LS1?

I'm just trying to make this as clean as possible. Perhaps I'll install a bleeder valve on the front coolant line to manually bleed it after a coolant change.

Hey Steve, I saw your pics before. The engine bay looks VERY clean.

Thanks for the reply. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I don't know about you, but I don't see any braided lines there in that pic with all that chrome and shine. <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

Magnus: The LS1 pipe has 4 pick-ups. One at the front of each head, and one at the back of each head. The rear pick-ups merge and then run under the center of the intake to merge with the front pick-ups. The LS6 pipe only has the 2 front pickups. If you get an LS6 intake you have to switch to the LS6 pipes, since there's no room for the LS1 pipes to run underneath the LS6 intake.

What year's your car? If 2001 or 2002 you already have the LS6 pipes.

I'm about ready to just ship my car to the Philippines. Pay 2 or 3 guys $1.25 per hour to polish until there arms fall off.

I figure in about a week or two, I may be able to out-bling Steve. But, then again, maybe not... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
