Question 1

What is the purpose of the cooling system hose?

Accepted Answer

It is a flexible or rigid element connecting the components of the cooling system, which allows coolant to flow between the engine, radiator and water pump.

Question 2

What is the difference between a silicone hose and a rubber hose?

No. Each car model has hoses with specific diameters, lengths, and bend angles – so compatibility with a specific engine or OEM designation is important.

Question 5

Do cooling system hoses affect engine performance?

Accepted Answer

Yes, indirectly. An efficient cooling system maintains optimal operating temperatures, which translates into stable power and lower fuel consumption.

Question 6

How often should you replace your cooling system hoses?
