Introduction: Replacing the Lower Radiator Hose on a Hyundai Trajet/sonata.

Picture of Replacing the Lower Radiator Hose on a Hyundai Trajet/sonata.

The 16year old hose in the car is soft and prone to failure. I ordered the replacement from and went ahead to do a proactive changeout.

As you see one of my doggies doesn't care about being proactive. Don't be like that. Take charge of your vehicle and replace aging components before failure.

Step 1: Removing the Old Hose.

A 10mm socket with Ratchet to remove the radiator fan. Next an 8mm socket to remove the radiator hoses. As you can see some corrosion on the engine side.

Step 2: Installing the New Hose.

Here is a side by side pic of the old and new lower hoses. Installation is the reverse of removal.

Step 3: Refill With Coolant.

Using low cost premix Coolant I filled the reservoir and let the air bubbles come out.

Step 4: Testing and Completion.

I started the engine and let it come up to temperature while observing for any leaks below the engine. Once there were no more escaping air bubbles in the reservoir, I put on the pressure Cap. I waited till the radiator fan came on and seeing no leaks I shutoff the car.

Now the car has a fresh radiator hose and ready for service.

You should run the heater to get any air out of there as well.

Our cars don't have the heaters connected. We live in a hot climate. Heat while driving a car can kill us here.
