The original cooling system in your Toyota Yaris is responsible for keeping your engine temperatures manageable. It does so by delivering a mixture of coolant and water from the factory radiator to the engine. Your radiator hose is what transports the fluid from one to the other.

How Your Radiator Hose Works

The water-and-coolant mixture travels from the radiator to the top of your engine – and the thermostat housing within – via an upper radiator hose. Once inside the engine, the mix cools the various parts and collects residual heat. It then returns to the radiator by wat of a lower hose that's attached to the water pump. The radiator's surface allows the heat to dissipate, and then the coolant returns for another trip through the engine.

How to Spot Radiator Hose Problems

Unfortunately, hoses will eventually get either too brittle or too soft to work properly. Signs of this include:

Pools of green, red, or yellow fluid pooling underneath your Toyota Yaris
Your engine begins overheating
The hose looks or feels like it has collapsed
You see cracks in the hose
