Radiator hoses
Radiator hoses are an important part of a car’s cooling system and are used to carry coolant between the engine, radiator, thermostat housing, expansion tank and the other components in the system. They therefore play a major role in ensuring that the cooling system works correctly and that the engine can maintain a stable operating temperature during both normal driving and heavier load. In this category you will find radiator hoses for replacement, upgrades and custom builds, where fitment, temperature resistance and reliability are important.
A radiator hose must be able to withstand heat, pressure, vibration and the chemical effects of coolant over time. This applies to standard road cars, modified cars, motorsport vehicles and custom projects, where the cooling system is often exposed to greater stress than standard. If a radiator hose becomes hard, cracks, starts leaking or loses its shape, it can lead to coolant loss, unstable temperature or, in the worst case, overheating. That is why it is important to choose hoses in a quality and size that match the specific application.
Radiator hoses are used both as moulded hoses for specific vehicle models and as universal solutions for projects where the cooling system is rebuilt or adapted. On standard cars, correct fitment in relation to the engine, radiator and original connections is often important. On modified or custom-built cars, more flexible solutions may instead be needed, where the hose length, diameter and bend must match a different radiator position, a different engine or a changed engine bay layout.
When choosing radiator hoses, it is important to look at factors such as internal diameter, length, temperature resistance, material type and where in the system the hose will be used. Some solutions are best suited as upper or lower radiator hoses, while others are used between smaller cooling components or in custom cooling systems. It is also important to consider available space, bend radius and how the hose works together with hose clamps, pipe fittings and the other parts of the cooling system.
