thanks but thats not the hose I was refering to.
It is the one closest to the number 2 in the diagram.
anyways I got all the old sealant off and hopefully fixed it

i had the same problem on mine when i accidentally broke the nipple off the radiator. i made the hole a little bigger then bought a brass fitting from lowes and jb welded it onto the radiator. been working fine without issues.
the fitting looks like this:

I like the red stuff, assuming the system is sealed and leak-free. These Toyota systems seem to, in most cases, be really well made and not leak too often, and after seeing the inside of many Toyota radiators using red for years, I was very impressed with how new they look on the inside vs other kinds of coolant. IMO the only one I've seen that keeps radiators as clean inside is the Mercedes godl stuff, basically Zerex G05 there.

Um I am surprised no one has mentioned this but there is actually a reason Toyota uses their Red coolant.
Silicates and Borates are avoided to prevent seal wear and aluminum corrosion.

Yes but the organic acids that are used in place of silicates are known to be particularly harsh on seals.
One american manufacturer, gm or chevy I cant remember, ran into this problem and faced a huge lawsuit because their o.a. based coolant was eating all the seals and plastic parts.

It was GM, the Dex-Cool fiasco.

This exposes hot engine components to air and vapors, causing corrosion and contamination of the coolant with iron oxide particles, which in turn can aggravate the pressure cap problem as contamination holds the caps open permanently.[24]
Honda and Toyota's new extended life coolant use OAT with sebacate but without the 2-EHA. Some added phosphates provide protection while the OAT builds up.[16] Honda specifically excludes 2-EHA from their formulas.
Typically OAT antifreeze contains an orange dye to differentiate it from the conventional glycol-based coolants (green or yellow). Some of the newer OAT coolants claim to be compatible with all types of OAT and glycol-based coolants; these are typically green or yellow in color (for a table of colors, see [15])
