The surface temperature.is below the point where their state changes to liquid or boiling point. Boiling Point Degrees above absolute zero: Helium - 4.2 Hydrogen - 20.2 and Methane - 111 degrees (At standard pressure- under pressure the boiling point rises - that is why propane tanks work for energy storage) . Helium Wikipedia

The boiling point of what?
Water boils at 373.15 Kelvin.
Gold boils at 3243 Kelvin.

Your question isn't a simple black or white question, it's all relative to how many PSI is your radiator cap and what mixture of anti-freeze your running, and also, how old or new the anti-freeze (coolant) is.

The pressure cap on a cooling system is the key to raising the boiling point of the 50/50 mix of antifreeze and distilled water. For every pound of pressure cap rating the boiling of point of the above mixture raises 3 degrees. If you had plain water in your cooling system with a 15 pound pressure cap the water would boil @ 257 degrees. If you had a 50/50 mix of antifreeze and water the coolant would boil @ 265 degrees with a 15 pound cap. The boiling point would raise to 270 degrees if you had a 60% antifreeze mixture with a 15 pound cap. If you had a 70% mixture the boiling point would raise to 276 degrees.

R22 has a boiling point of about negative 43 degrees F. Different refrigerants have different boiling points.

Sounds to me like a blown head gasket. Even if your vehicle is not warmed up, if your reserve tank is boiling fluid out of it when the engine is cool, it's most likely losing compression from it all going to your reserve tank. And thats why it's fluids coming out of your reserve tank. BUT, if your radiator is clogged then the same thing could happen. So i would start out cheap before you have to replace a HG.

There is no timing adjustment , the pulse generator can only be installed in one position. Perhaps the vacuum advance mechanism under the pulse generator is the source of whatever problem you are having. Make sure the vacuum line going to vacuum advance is not cracked or leaking and that vacuum advance itself still working correctly. Applying vacuum to the advance, the base plate should start moving at 1.6 in. Hg (40 mm Hg) and stop moving at 3.2 in. HG (80 mm Hg).
