Before you use the napa cool check it first sometimes you don't need it and supposedly it is just as bad to have too much.

The silicates in the coolant do not disolve well in ethylene glycol.
They need good ol' H2O to stay in suspension. Not enough water and they precipitatae out on cool surfaces. Plugged radiator is the result. If you don't let the radiator dry, it can be boiled out. Once it dries it has to be physically removed.
