The Radiator Coolant keeps the engine from overheating while protecting it from rust and corrosion. It also prevents it from freezing, so is sometimes called anti-freeze (antifreeze). Straight water can be used, but is subject to rust and to freezing, and non-distilled water can cause particle build up in the cooling system.
Fill the radiator with a distilled water in a 50/50 mix of coolant/antifreeze. If you live in freezing areas, check the coolant container for instructions (which may require a 30/70 mix in very cold areas).
- Water capacity: 4.9 liter (5-3/16 US quart, 4-5/16 imperial qt)
Many of these brands listed below have changed names. Any modern antifreeze/coolant that is compatible with aluminum parts should be acceptable. The Datsun 1200 uses an aluminum head and water pump.
