Think of the overflow as an expansion tank. The fluid gets hot, expands, and goes to the tank. As the fluid cools, the check valve in the radiator cap allows the fluid to re-enter the system. Air in the top of the radiator serves the same purpose with no overflow, but reduces your cooling.

After some consideration, I think I'll just paint the bottle black to help it blend in a little. I don't plan on tracking the car, but I auto-x about once or twice a month (not sure if the tech there would car or not, but better to be safe than sorry.) The car runs great, never has cooling problems, I don't really want to mess that up. Thanks for all your replies! (especially the intelligent ones lol)

The painted overflow bottle looks good, but (duh) then you can't easily read the low/high lines on the side.

Hmmm .... maybe paint it but mask off a small "window" so the lines are visible. I like the red-on-red!

Who said anything about weight reduction? And I already got rid of the washer fluid bottle, I never let my car get dirty enough to use it anyway. I doubt I'd notice a 100 lb reduction in my daily drive, let alone the three pounds of plastic and fluid in both of the tanks. I'm cleaning up the bay specifically for aesthetic purposes. I'll probably do a mild wire tuck and lots of polishing when the car gets put away for the winter.

Take off the cap and peek inside...? How often do you really need to check the coolant anyway?

FREEZING POINT DEPRESSION
Red Line WaterWetter® does not significantly reduce
the freezing point of water. If the vehicle will see
freezing temperatures, an antifreeze must be used.
Water expands approximately 9% upon freezing
which can cause severe engine damage. Even in
summertime, the use of air-conditioning can blow
freezing air through the heater and cause freezing of
the heater core unless approximately 20% antifreeze
is used.

Yet another reason to remove AC during a turbo install... And that actually has a decent bit of weight savings.

Yeah, I pulled mine when I did the initial install about four years ago. Primary motivation was easier routing of the I/C pipes. The A/C didn't work anyway. Never regretted it until I moved back to Florida.

I'm getting soft. My next car will have A/C. And power steering. And cruise control.

And 300 WHP.

I would never buy that, it would only take an hour at the most to make that in my garage.
