What if it goes bad? What will be the symptoms? How will we be able to replace radiator hose without any problem or is it a DIY job? Find out in our article!

What is a radiator hose?

You must be wondering how radiator or coolant hose can control the temperature of coolant in the engine. Are they really capable of preventing engine overheating?

First of all, you must know about the composition of radiator hose i.e. what it is made up of. Radiator hose is a rubber device whose tubes are made of synthetic rubber which can resist heat, vibration successfully.

Radiator hose manages the coolant flow from engine’s water pump to the heater. Two types of hoses are generally used as upped radiator hose and lower radiator hose depending on model and need. The upper hose generally connects top of radiator to top of the engine and lower hose connects the lower part of the radiator to the water pump to keep the coolant flowing without interruption.

How do they help in controlling engine overheating? They carry coolant through the radiator and back through the engine to keep it operating at a specified temperature or required temperature.

As the hoses are made of rubber so by time they can develop cracks because of high temperature so it is very important to maintain and keep an eye on them to avoid further engine complications.

You can buy car radiator hose easily at any auto parts store online, so get them replaced quickly! Now check out the prominent symptoms of bad radiator hose.

Leaking coolant

Low coolant? Even after you refill, the problem of low coolant persists? There might be a leak in the radiator hose. Coolant is very easy to identify as it has a sweat smell and generally leaks through the radiator hose or radiator.

Keeping your car’s radiator running on low coolant is not a wise thought. You could end up stranded on road and engine overheating is not to be forgotten.

If you think car engine replacement is the easiest to do, then you are mislead because it is definitely going to hit your fortune for sure! To get the exact location of the leak, take your car to a trusted mechanic and then let him fix it for you! Just make sure you don’t ignore it for too long.

Engine overheating


Engine overheating is just not good! There can be various other culprits that cause engine to overheat so best idea is to take assistance from a professional.

But engine overheating is definitely related to car cooling system parts. Cracks and leaks are worst enemies of a car’s engine. If your car’s radiator hose has got one, then it is obvious for the engine to perform poorly.

Just stop driving if you get an alert message on your dash that the engine’s temperature is above normal or most common visible sign is of white smoke coming from the front part of car. Because, you can still revive your car from overheating if you stop driving but continuing it might halt your car forever.

Engine is heart of your car! Keep it cool and change radiator hoses whenever necessary.

DIY- Install coolant hose

  1. Stop the car and make the engine rest of at least 10 minutes.
  2. Remove the worn hoses and drain the cooling system. It’s a good chance to clean any corroded fitting so do this using a wire brush.
  3. Loosen the clamps at each end and once you have the clamp off, remove the radiator hose.
  4. Changing a coolant hose also means installing a new hose clamp. Slide them over the replacement hose but don’t tighten them.
  5. Slip the hose onto the hose end and then slide the hose onto the fitting.
  6. make sure the hose clamp is positioned so the tightening device is easy to reach.
  7. Check to ensure the clamps are located beyond the raised bead of the connector and tighten them.
  8. Now refill the coolant system with standard 50-50 ratio of coolant and water. Make sure to use distilled water instead of mineral one.
  9. Finally check visually for any impending leak and treat them along the way. Even if you need to bleed the cooling system don’t refrain from doing so. This will help the cooling system in performing better.
  10. Job’s done! If you can’t seem to locate or do as directed, don’t forget to go through your car’s manual.
