Get yourself some RMI-25 for that water pump/radiator. This stuff sounds too good to be true but we've been using it in all my family's cars for the past 15 years and have never had to replace a water pump or radiator since then. And it's cheap, 30 bucks for a quart which is enough to last for several years.
Oooooh, boy. Be careful doing this.........G12 coolant does NOT play nice with other coolants and additives. You could easily end up with a sludged-up, clogged cooling system that then requires major work to fix.
