Exclamation Coolant Leek Easy Fix?

I have been adding coolant for the past month not sure where it was going. I finally decided to take the front passenger tire off. I removed the plastic pins holding the plastic wheel well shroud. I was able to watch the coolant run down from a plastic tee down the house and onto the ground. See image below.

It was leaking for a while because of the color of the silver heat-shield that fits over the hose is now all tarnished with an orange and red color.

Can I just replace the plastic tee or do I need to replace the hose too? Does the hose press fit into it? Any suggestions and part numbers would be greatly appreciated.

This is a common leak point on the Commander. The OEM tee fitting is plastic and has a plastic ring as a clamp to hold the hose to the tee. Over time the hose shrinks and/or the plastic ring loosens and the seepage starts. The tee is not available separately but it could be replaced if you can find one. Goodyear makes a replacement hose assembly (google it)with metal tee and metal swage clamping the hose. I replaced my leaking OEM hose assembly with this one about a year ago. I believe you will find that replacing the hose assembly with the tee fitting already in place is much easier than trying to replace the tee and hoses separately.

If it's leaking from the area where the hose fits over the clamp because the plastic ring has stretched/loosened over time, maybe just replace plastic rings with metal hose clamps and see if that secures the hoses firmly enough to stop the leak.

If the plastic tee is damaged - and that's what's causing the leak, then you'll probably be forced to replace the whole assembly as bdalameda suggested.

I tried removing the plastic clamps/rings when I had these leaking. Very difficult to remove these as it seems these plastic rings are molded or some type of press/ heat process is used to install them at the factory. Not much working room either. I tried to use a dremel type tool to cut them off but it was just about impossible not to damage the hose ends. The aftermarket hose assemblies from Goodyear were not too expensive so I went ahead and replaced them.

It sounds like a complete replacement with aftermarket parts is the way to go.
Thanks for the heads up.

What would I google? I am not sure what it is called or the part number. Can you suggest the search string?

Look up heater hoses for a Commander. CariD has them made by Continental - looks identical as the Goodyear hoses I installed. See link:

Make sure you order the correct ones for your year model and engine.
