What do you need to know about cooling system hoses?
In order to withstand the vibration and movements of the engine without breaking, cooling system hoses must be flexible. To achieve this, traditional (and OEM) coolant hoses feature outer layers made of a durable rubber compound. Underneath the rubber outer layer is a flexible fabric reinforcement mesh.
How often do coolant hoses need to be replaced?
Carmakers do not consider coolant hoses a routine maintenance item, so it follows that there can be a lack of guidance about how often these hoses should be replaced. Without a specific mileage point or time interval to use as a reference, it’s crucial that you stay informed about how coolant hoses work and how they wear out.
Why are my coolant hoses degrading from the outside?
This coolant hose degraded from the outside. Coolant hoses also degrade when their outsides are exposed to direct contact with oil or other contaminants. This can occur, for example, when hot oil drips onto the rubber from a leaky engine.
When do you replace the coolant hoses on a Chevy Cruze?
In the past 2 years, I have replaced, among other things, the majority of my cooling system on my ’12 LTZ RS. All that is left is the water outlet (which is cracked,) and all coolant hoses.
