What's Cool Top Rated Search Find automotive web sites across Canada. Late summer heat, hard working equipment, and an engine that has had a couple years of service. All these conditions add up to the possibility of cooling system failure. Your truck, tractor, combine, or any other water cooled equipment are all subject to wear and tear on their cooling system.
Hoses are the most common failure.
The rubber hoses harden with age and heat and begin to crack where they flex near their connections. A simple visual inspection should locate cracked hoses. Less common problems include hoses that have deteriorated internally. The inner lining of the hose can separate and block the coolant flow. Check for restricted coolant flow by feeling along the hose and noting any changes in temperature.
