The hoses are an integral part of the cooling system in conventional water-cooled engines and a critical component in safeguarding the engine from excessive heat build-up and premature and expensive failure.
The hoses allow the efficient transfer of coolant between the engine block and the radiator.
If the hose has a hard feel or visible cracks along its length or is brittle then it has been effected by excessive heat.
It is recommended that hoses be replaced regularly as heat deterioration can produce hidden damage to the hose and over time that can cause the hose to burst and fail.
At ATIC Mechanical we can do a full cooling system flush for only $77.
