I was removing some heatshield underneath my car because it was rattling, and came across this hose that was covered in grease and oil. It probably needs replacing. Is this the lower radiator hose?

Sorry about the pictures I was under the car and my phone apparently
doesn't focus well.

It looks as if the hose is thin and around 4-5 inches long and connects to the bottom of the radiator.

 

looks like the hose to the transmission cooler...yes...definitely is.

 

I wouldn't worry so much about replacing the hose as I would trying to figure out what's leaking on it. That doesn't look good........ My car has 120K and I've never had anything like that in that area, you might have a radiator leak somewhere.

 

I agree.

IS that coolant, or Trans FLuid?

 

So a Transmission Cooler Hose?

It seems like is Black Oil on it. I think Im leaking Oil.... But I don't notice any oil leaks on my driveway....

I remember replacing the O ring gasket 2 years ago. Can't trust Jiffy Lube these days...

 

It looks reddish now that I look closely at it. I can't tell where the leak is, but it might be as simple as moving and retightening the hose clamp.

Grab some gunk engine degreaser and clean the spot. Drive it for a day and then recheck to confirm where the leak is coming from and then repair it. Degrease it again, drive for a day or two and make sure it's leak free.

 

If it is reddish...it is tranny fluid

 

I hate it when my tranny leaks fluids, gotta get him to clean up before he leaves......

 

Hey oh!

 

Somebody has been in there b4, 'cause those aren't o.e.m clamps on the hose(s). The fittings that go into the rad look pretty rough too. If you're lucky, just a hose and a clamp. If you're not, could be replace the fittings or even rad and clamps and hoses. Clean the area and check it out.

 

I'm confused is it an engine oil cooler hose #5 with #6 clamp.

Or the cooler hose #20 but no clamp there....

I ain't lazy just trying to get some advice from you experts.

 

Its none of the hoses you have pictured. Its for the transmission cooler not engine coolant.

Just need to purchase standard transmission or fuel line from auto parts store and cut to length.
