Coolant & Oil Tanks, Radiator Caps, and Breather Valves

Reliable Cooling and Oil Systems Start Here

This collection covers everything you need to manage heat and pressure in your custom vehicle.
Whether you're building a street kit car or tuning a race engine, reliable fluid systems are essential.

You’ll find parts for coolant, oil, and breather systems.
That includes oil catch tanks, radiator caps, and coolant expansion tanks.
Everything is chosen for quality, compatibility, and performance.

Why These Parts Matter in Custom Builds

Overheating is one of the most common causes of engine failure.
That’s why we offer a full set of tools to manage coolant flow and oil vapor.
These parts help balance pressure, prevent leaks, and simplify maintenance.

Each radiator cap is tested for fit and finish.
Each breather tank is designed to capture oil mist without restriction.
Each rubber seal is cut to handle coolant and oil temperatures.

When building a kit car, you need parts that install easily and work reliably.
That’s what this collection offers.

Built for Builders and Tuners

Many of these parts were developed with help from custom car builders.
We listened to what racers, hot rodders, and restoration experts needed.
Now you can get it all in one place.

🔧 Pro Tip: Always match your radiator cap pressure to your tank and hose ratings.
An under-pressured system can boil over, while over-pressuring risks failure.

Materials You Can Trust

Most tanks are made from aluminium or stainless steel.
They're corrosion-resistant and ready for daily driving or track abuse.
Seals and caps are made with fuel-safe rubber and reinforced plastic.

This means fewer leaks, better performance, and a clean install that lasts.
You can even find brushed finishes and stealth black options for a tidy engine bay.
