CUSCO Type A High Pressure Radiator Cap
For 1983–1987 Toyota Corolla Levin / Sprinter Trueno AE86 4A-GE & 1985–1987 Toyota Corolla Sport GT-S AE86 4A-GE
Overview
The CUSCO Type A High Pressure Radiator Cap is a direct-fit cooling-system upgrade for 4A-GE-powered Toyota AE86 applications. Its higher pressure setting increases the coolant's boiling point, providing additional temperature margin during demanding driving conditions.
A reinforced pressure-valve spring and heat-resistant silicone sealing design help maintain cooling-system pressure while reducing coolant vapor and air-bubble formation that can reduce heat-transfer efficiency.
Key Features
- Type A high-pressure radiator cap
- 1.3 kg/cm² pressure rating
- Approximate coolant boiling point of 126.5°C / 260°F
- Higher pressure setting increases coolant boiling resistance
- Reinforced main pressure-valve spring
- Heat-resistant silicone sealing design
- Helps reduce air-bubble formation within the cooling system
- Direct replacement for the correct Type A radiator-cap configuration
- Designed for Toyota AE86 4A-GE cooling-system applications
Cooling System Performance
Increasing cooling-system pressure raises the temperature at which coolant begins to boil. This provides additional protection against localized boiling and vapor formation inside the engine and radiator during elevated operating temperatures.
Maintaining coolant in a liquid state helps preserve effective heat transfer through the engine and radiator, making this radiator cap particularly useful for performance-oriented, spirited-driving, and motorsport-focused AE86 builds.
