    it is good maintenance for the coolant to be changed at 50k. the dirt your talking about should be gone with a good chemical flush. we do it for the same price. god move to get it done.

    I don't see how a fungus can grow in 210-220 degree heat, can you? Most things die, when you pour boiling water on them.
    A coolant flush is ok and the price is about right though I question the fungus.
    Anti-freeze loses its effectiveness after about 3 yr or 30-50 k, even though the factories try to sell the 'it's good until 100k'
