How to Troubleshoot the Flood Coolant System


When using a cold saw, it is important to ensure that the coolant pump is put under water. If you put the coolant pump under water, you can prevent unnecessary damage. The coolant is dispensed on the blade of your cold saw from the coolant fitting located on the upper blade guard. The tube provides the coolant to the cold saw through the pump in the base of the machine.

A proper coolant system should have a surge tank to prevent the entrance of air.  Besides the surge tank, the radiator should be full all the time when the cap is removed. If the surge tank is not full, it can be either the surge tank is empty or a leakage exists in the system. For surge tank without fluid, you can remedy the problem by pouring in a mixture of cryoprotectant and water. The mixture of cryoprotectant water will protect the system from erosion by chemical and increase the cooling rate. If a leakage exists in the flood coolant, the rubber gasket that seals the radiator cap must be replaced. The radiator cap is located on top of the neck.

It is a standard for the flood coolant system to have at least 18 psi for five minutes. You can perform the test yourself or bring it to an automobile or repair shop to perform the pressure test.

The flow restrictions in the coolant system are derived either from the debris or corrosion in the tubes. The debris in the tubes can cause the radiator to not release heat into the atmosphere efficiently. If your radiator has cool spots, it is likely that you will face with this problem. One way to remove the debris is by reverse flushing the radiator. Chemical flushing will help to lower the occurrence of corrosion restrictions. If the radiator has severe flow restriction problem, you should seek professional help. The airflow restriction in the radiator is mainly caused by obstacles such as dirt, leaves, and insects.

The thermostat has an important function in the coolant system. At the minimum, you must use a “minimum” hi-flow unit. The thermostat that available at the discount store should not be purchased since its temperature will increase when pressure builds. When the RPMs increase, the water pump pressure can increase the outlet restriction indicator of the thermostat. This usually happens on cheap thermostat. Thermostat that is more expensive will not be easily affected by the outlet pressure. Coolant system that suffers from overheating problem should be replaced with a quality balance thermostat.

In addition, the transmission cooler and engine oil to water cooler can increase the burdens of the radiator core of the coolant. If external cooler is used, the core area will be increased and gives you more capacity. Due to the high oil temperature, you should separate the transmission cooler and oil to water oil coolers.

The coolant system can work efficiently with a sufficient supply of an oil base or synthetic coolant such as Do All and Lenox coolant. The coolant should be replaced frequently. You can purchase the coolants from your local home improvement store.
