Some Toyota Hilux owners upgrade their cooling systems for better performance, especially in hot climates o r for off-roading.

🛠️ Popular Cooling Upgrades:
✔️ Larger Aluminum Radiator – Better heat dissipation than stock.
✔️ High-Performance Coolant Additives – Reduces engine temperature e.g., Red Line Water Wetter.
✔️ Additional Electric Cooling Fan – Improves airflow in extreme heat.
✔️ Oil Cooler Installation – Helps keep engine oil temperature low.

📌 Verdict: If you drive in hot weather o r tow heavy loads, aftermarket cooling upgrades are highly recommended.
