Lower radiator hose replacement

I attached the process from the manual. You should not need to remove much in order to get to it. It may be needed to get to it from underneath. Most all these processes assume you are working at a shop with a lift so they take that for granted.

Let me know if you still need more info and we can see about getting more details. Thanks

Are you looking from the top or the bottom? I would suggest looking from under the vehicle and then seeing what you may need to remove. Unfortunately it is one of these repairs that you are going to have to just look at what is in your way and remove it. I have not done one on a Malibu in a couple years so I don't remember taking anything special off.

Also, you are going to want to make sure you depressurize the system before you attempt this otherwise it is going to spray coolant all over.

Hello, I'm Danny.

Here is a basic tutorial on how to replace radiator hoses:

The question you asked was if the system is pressurized but mainly when the engine is running and at operating temperature is what you need to be aware of. When the engine is cool and not running is when you should perform this repair.If you want better access to the lower radiator hose you might consider removing the lower air baffle underneath the radiator.It is just a few plastic screws.When the cooling system has cooled off you can then remove the radiator cap to remove the residual pressure without worry of burn. I've attached a picture below of the air deflector-baffle.Hope this helps and thanks for using 2CarPros.
