Honda R&D developed this coolant specifically for use in aluminum engines. It uses high-tech organic non-abrasive corrosion inhibitor instead of silicates for maximum protection.
Advanced Type-2 "Blue" formula is 100% compatible with and replaces the original "Green" coolant. It protects in temperatures from -34F freeze point to 265F (at 15 PSI) boiling point, and it is ready to use straight from the bottle 50/50 blend.
- Uses high-tech organic corrosion inhibitors instead of more commonly used silicate corrosion inhibitors.
- Unlike silicates, HP Coolant's organic corrosion inhibitors won't gel and cause radiator plugging.
- It is also more stable for a longer shelf life and its formula won't act as an abrasive to mechanical water-pump seals (which could cause leaky seals).
