1993 Toyota Hilux Surf Coolant — What it does and how to look after it

Coolant is absolutely relevant and used on the 1993 Toyota Hilux Surf. Toyota’s factory documentation for this generation — including the Toyota 4Runner/Hilux Surf Repair Manual (1990–1995 range) and the engine repair manuals for the 3VZ‑E petrol V6 plus the 2L‑TE and 1KZ‑TE diesels — specifies a pressurised liquid-cooling system filled with ethylene‑glycol–based coolant. The owner’s maintenance schedule for these models also lists periodic coolant replacement. So, yes, this Surf runs a conventional water pump, radiator and thermostat with Toyota Long Life Coolant in the mix.

In this rig, coolant isn’t just coloured water. It pulls heat out of the engine, stops freezing on frosty mornings and raises the boiling point on brutal summer climbs. Just as importantly, the Toyota-approved coolant package protects alloy heads, radiators and the water pump with corrosion inhibitors, helping the old girl keep her cool on long Kiwi or Aussie road trips, towing, or beach missions.

For a 1993 Hilux Surf, the recommended choice is Toyota Long Life Coolant (red), mixed 50/50 with demineralised water. Don’t top up with random green or blue coolants, and avoid mixing types — if the history is unknown, book a full flush and refill. While some owners migrate to Toyota Super Long Life Coolant (pink), that should only happen after a thorough flush
