The hot tip I got for coolant gallery of block cleaning was
- 10% citric acid (from a home brewer shop) mixture with water, let it soak for 24 hours
- if there's still chunks in there, 5% w/v for 2 days
- wash out with water and don't leave the mix to dry
- then 40g/litre sodium hydroxide (also from a home brewer shop) and let it soak for an hour
- rinse out the residue with water and don't let it dry - use compressed air to aid drying
