To maintain the of an is one of the vital aspects of design because no will have a good lifespan with poor . In other words, poor will always give rise to overheating followed by high noise and subsequent wearing and tearing of parts which are very detrimental to the life of the .
To have the life span of the preserved, there are necessary things one need to put in place which the flushing and the cleaning of the is among. Generally, modern do come with and water circulating units, including the porous holes created within the for the purpose of making water to circulate within the cylinder where the major activities in the do take place. However, due to constant use and longtime service of the , the holes and water circulating channels within and outside the gets blocked or obstructed causing reduced water flow and causes a rise in the .
We shall be dealing with the steps to treat and maintain the cooling system of internal combustion engines using a as our reference and an example. Below is the procedure to ensure the of your is in order.
- Look through the filter hole. If the tubes are covered with scale deposits, use a proprietary cleaning compound to loosen them following the maker’s instructions.
- Flush the radiator by hosing water at mains pressure through the filter hole. If the flow through the bottom hose stub is restricted, it will be necessary to backflush the radiator. Push a garden hose into the bottom radiator stub (wrap it in a rag to prevent leakage). Turn on the tap and run it until the water runs out of the filter hole. In some cases, it may be necessary to remove the radiator, turn it upside down and again back-flush it by hosing water in through the bottom hose stub. If this does not improve the flow of water and the engine persistently overheat, consider de-scaling it using a powerful alkaline solution, but this later process requires a good knowledge of radiator maintenance and .
- Clean the outside of the with plenty of water and soft-bristled brush to any debris blocking the airflow.
- To flush the heater hoses at the . One will be clipped to the cylinder head or the inlet manifold and the other will be attached near the water pump. With the heater control on ‘hot’ or the cylinder head water open, fit the mains hose to the heater hose disconnected from the main pump, i.e when you turn on the water there should be an unrestricted flow from the outer heater hose, continue flushing until clear water emerges.
- The thermostat must come out in order to flush the cylinder . On most , it is located under a housing at the cylinder head end of the top hose. Unbolt the housing, it, and scrape away the around the edge of the thermostat. The thermostat should now lift out. It may, however, be corroded firmly in place. If so, scraping debris from the edge of the thermostat, using a small screwdriver, will allow it to be lifted.
- Disconnect the bottom hose at the water pump end. Insert the mains hose in the thermostat hole and turn on the water. There should be an unrestricted flow from the bottom hose stub. Flush the system until clear water emerges.
- Start the reassembling of the system by reversing the process.
With the steps mentioned above, it is believed that your will be in good condition always, thereby ensuring the prolonged lifespan of your . However, if you have an additional contribution to this post, please drop it through your comment.
