Introduction: 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 Amazon.com 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.
We have a be nice policy.
Please be positive and constructive.
