High-Performance Cooling Systems - Oil Coolers, Transmission Coolers & Heat Management

Keep your engine running at optimal temperatures with our comprehensive range of performance cooling systems designed for Australian street machines, race cars, and custom builds. From electric fans and water pumps to oil coolers, transmission coolers, and intercoolers, we stock everything you need for efficient heat management and reliable performance.

Engine Cooling Components

• Water Pumps: High-flow electric and mechanical water pumps for increased coolant circulation and superior cooling efficiency
• Electric Cooling Fans: High-CFM electric fans with slim profiles for improved airflow and reduced engine load compared to mechanical fans
• Radiator Caps: High-pressure radiator caps (16-32 PSI) to raise boiling point and maintain system pressure in performance applications
• Water Necks & Thermostat Housings: Billet aluminium coolant outlets and thermostat housings for custom cooling system plumbing
• Coolant Hoses & Fittings: Silicone hoses, AN fittings, and adapters for leak-free cooling system connections
• Overflow Tanks & Expansion Tanks: Aluminium and polished stainless catch cans for pressurized cooling systems

Oil Cooling Systems

• Engine Oil Coolers: Plate and tube oil coolers (10-40 row) with AN fittings for reduced oil temperatures and extended engine life
• Transmission Oil Coolers: Dedicated transmission coolers to prevent overheating in towing, racing, and high-performance applications
• Differential Coolers: External diff coolers for race cars and vehicles with limited-slip differentials
• Oil Cooler Mounting Kits: Universal mounting brackets and hardware for secure oil cooler installation
• Thermostatic Oil Sandwich Plates: Temperature-controlled oil flow to maintain optimal oil temperature range
• Oil Cooler Lines & Fittings: Braided stainless hose and AN fittings for professional oil cooler plumbing

Forced Induction Cooling

• Intercoolers: Air-to-air and air-to-water intercoolers for turbo and supercharger applications to reduce intake air temperature
• Intercooler Piping: Aluminium mandrel-bent piping kits for custom intercooler installations
• Intercooler Spray Systems: Water/methanol injection systems for additional charge cooling and detonation suppression

Cooling System Accessories

• Temperature Gauges & Sensors: Accurate monitoring of coolant, oil, and transmission temperatures
• Cooling Fan Controllers: Adjustable thermostatic switches and PWM controllers for precise fan operation
• Radiator Hose Adapters: AN to barb adapters and reducers for custom cooling system plumbing
• Coolant Additives: Water wetter and corrosion inhibitors for improved cooling efficiency

Why Upgrade Your Cooling System?

Factory cooling systems are designed for stock power levels and normal driving conditions. Modified engines with increased horsepower, forced induction, or track use generate significantly more heat that factory components can't handle. Overheating causes detonation, oil breakdown, transmission failure, and catastrophic engine damage. Upgrading to a performance cooling system maintains safe operating temperatures, protects your investment, and ensures consistent performance in demanding conditions.

Cooling System Sizing Guide

Oil Cooler Sizing: Engine oil coolers typically range from 10-row (mild street) to 40-row (extreme race). Transmission coolers should handle 50% of transmission horsepower rating (e.g., 400hp transmission = 200hp cooler capacity). Larger is better for oil cooling—you can't over-cool oil.

Electric Fan CFM: Calculate required airflow at 2,500-3,000 CFM per 100 horsepower. Dual fans provide better coverage and redundancy. Pusher fans mount in front of radiator, puller fans mount behind (pullers are more efficient).

Common Cooling System Applications

• V8 engine conversions requiring upgraded cooling capacity
• Turbo and supercharger builds with intercoolers
• Race car preparation and track day vehicles
• Towing and heavy-duty applications
• Hot climate operation and desert racing
• Engine swaps where factory components won't fit
• Show cars requiring polished or custom cooling components

Cooling System Installation Tips

Oil Cooler Placement: Mount oil coolers in clean airflow away from exhaust heat. Position transmission coolers before radiator to prevent heat transfer. Use thermostatic sandwich plates to prevent over-cooling in cold weather.

System Bleeding: Properly bleed all air from cooling system after installation. Air pockets cause hot spots and overheating. Run engine with radiator cap off until thermostat opens, then top up and install cap.

Coolant Selection: Use quality coolant with corrosion inhibitors. Distilled water with water wetter works for race applications. Never run straight water in street cars—it causes corrosion and freezing damage.

Performance Benefits

• Reduced engine and oil temperatures for increased reliability
• Consistent performance in hot weather and track conditions
• Extended engine and transmission life through proper cooling
• Prevention of heat-related detonation and power loss
• Improved oil viscosity and lubrication at operating temperature
• Increased power from cooler, denser intake charge (intercoolers)
