What is a radiator coolant hose and what does it do?

The car radiator hose takes coolant to and from the radiator. The coolant flows through the water pump and into the engine block, where it cools things down to prevent overheating. Without a radiator coolant hose, connections between the engine and radiator become stiff and inflexible which further disrupts the engine's function and purpose.

When should I replace my radiator coolant hose?

This is not the type of part that you need to religiously replace every so many miles, but if it is leaking then you should replace it as quickly as possible to avoid any major problems.

What happens if I don’t?

If your radiator coolant hose is leaking and you do not replace it right away, you could be putting your engine at a significantly increased risk of overheating. That can cause significant other damage.

How to do it: replacing your radiator coolant hose:

  1. Figure out which of the car radiator hoses are leaking so that you know what to replace. You can do this by running the car while it is parked on level ground with the emergency brake on. Look for visual cues of damage or leaks. Turn the engine off and inspect again. Hopefully you can pin point the leak.
  2. Once the engine cools off, drain the coolant into a bucket by opening the drain plug on the bottom side of the radiator.
  3. There are a couple of clamps on the car radiator pipes or hoses, so loosen them to improve your access to it.
  4. Now that it is loose, grab the hose and work it free of the end of the radiator that it is attached to. Since you are replacing it anyway, if you have trouble removing it you can use a knife or other sharp object to cut the hose.
  5. Take the new hose and seat it firmly over the stub or valve into the radiator so that it does not leak in the future.
  6. Use the clamps to tighten the hose as much as you need to.
  7. Close the drain on the bottom of the radiator and fill it up with coolant.
  8. Start the engine and warm it up. Look for leaks again.
  9. Drive the vehicle as normally as possible for a day or two, while monitoring your temperature and looking for signs of leaks.

Anything else I need to know?

For some vehicles, you may need to remove some ancillary parts to get to the Spark Plug Replacement, so be prepared for that. If you run into problems with that process, you may need to do some research to get instructions that are specific to your vehicle.

If you notice your leak slowly at first and have time to buy the parts ahead of time online, you can save money and make sure that you get the perfect fit.
