Pull the heater core hoses off and flush it out with a garden hose

If no one from the future stops you from doing it, how bad of a decision can it really be? -
X2. Just alternate back and forth until it runs clear. Look up a thread called. A nice tidbit for those with barely any heat

I extended hoses upwards, and filled with phosphoric acid and let it sit overnight to eat crud.

I bought a Prestone Radiator Flush and fill kit for $4 at WalMart. Works perfect. Flushed out my system. Added a proper 2 stage t-stat and heat!!! YEA...Comment
