You will face overheating your car engine, which can damage engine parts badly.

Here, we will direct you how to replace lower radiator hose. Usually, two radiator hoses are used with the car radiator in cooling system. The upper radiator hose provides coolant from car engine to the radiator, and it connects to the thermostat assembly. Simultaneously lower radiator hose provides coolant from the radiator to engine. The car engine should always remain at normal operating temperature for getting better efficiency.

If you notice lower radiator hose leaking at clamp or other places, you will face engine overheating, which is very harmful to car engine components. So, after identifying the radiator hose leak, replace the hose immediately.

If would be best if you refill radiator with the recommended coolant for your car, but keep in mind that you must tight the drain nut properly before that.

Finally, install the radiator cap. Start the vehicle and allow your car engine to reach an operating temperature, which will allow the system opening the thermostat bulb. Then add antifreeze to go the specified level. Drive your car to find out any leakage and also monitor the engine temperature gauge.

After that, shut it down as well as allow it cool. Then recheck the coolant level for final confirmation. If the coolant is clean and of good quality, you can reuse it. After setting the hose clamps, if you find it week than before, replace it immediately. Put on your safety glasses before starting the coolant replacement process.

Aug 16, †∑ Radiator hoses connect the top of the radiator to the top of the engine, as well as the bottom of the radiator to the water pump. Radiator hoses are essentia. Use a utility knife or razor blade to cut the hose linearly where it is connected. Cut through until you feel metal on the inside and then gently pry up the edges and peel the hose end off. Once the hose is removed take the time to clean the surface of the metal before installing the new hose. Use fine sandpaper, steel wool, etc.

The radiator is an essential part of your cooling system. As coolant pass through it, the coolant is cooled and returned to the water pump to cool the engine. Hot coolant is forced through thin passages in the radiator element. Fins disperse the heat across more surface area and air passing over the fins takes away the heat. As your car ages corrosion builds up in these small passages in the radiator element.

This restricts or blocks coolant flow and causes the engine temperature to rise. If your engine is running hot, damage can occur and over time can result in lowering your engine life. This also overtaxes your oil causing thermal breakdown. In this tech article we will go over all the steps needed to replace your radiator. We strongly recommend draining your cooling system before removing your radiator. Just pulling off the lower radiator hose will easily cause a mess in your garage or driveway.
