My mini is leaking some yellow fluid near the rear axle!
Any ideas?

 

Have you checked the battery box? Maybe it's battery acid. Unless you have a MC, in that case I don't know what it could be.

 

The battery compartment is super dry. No leaks at all.
the leak is definately not coming from the engine bay i know. but from somewhere mid-length to the back of the car.

 

im scared!

 

Check around the exhaust for any type of debri. Maybe a plastic bag or some other type of foreign material.

 

This is a 2003 cooper s by the way.

I drove 150 miles through an insane blizzard yesterday here in new york. I think I scared my mini lol.

I've checked under the car and there are no foreign objects. I waited for a couple of minutes and don't see the leak but where ever i went today, i leave behind a trail of yellow snow.

My washer fluid is blue so thats not it. What is yellow?

 

When you were driving through that blizzard, could you have driven through some yellow slush? Could that still be dripping off?

 

It is time to take a good look under the car. Ramps, or jack with jack stands may be in order. Or, pull into a real service station with a lift and have them put it up just for a look see.

Check your brake fluid level, should be clear, if old will be brownish, but check.

YD

 

Uumm, you know what they say about yellow snow...
Definetly jack the car up and get under there and eyeball that thing (use jackstands! -sorry, I'm a safety nut). Start from where the drip hits the ground and work your way forward; use your fingers to feel for the stuff as fluids tend to work their way backwards while driving. Good luck.

Check your brake lines they travel along the channel under the car. Remove wheels and check calipers, and look for leaks around shocks. Basically as posted above, get the car up in the air and look around underneath. Trans will be red or smelly yellow, antifreeze comes in green , yellow, orange, blue, brake fluid new is clear like honey and older is dark like soda. Oil is dark, PS Hydralic I haven't looked. And washer fluid is blue or yellow.

 

 

First thing that comes to mind when seeing that color is Prestone Extended Life Universal Antifreeze. It's a bright yellow and if you've had service done at a non-dealer, it is used by many shops 'cuz it's compatible.

 

Not to sound rude, but are you sure it isn't just urine from a pet?

 

Oh Dayam
Then I remembered that I used yellow antifreeze =x
Will jack car up tomorrow to verify.


Before it was snowing, it was raining a bunch near Binghamton, I took pit stop to pee and remembering seeing steam coming out from the grille.

Would that just be the evaportion of rain water on the radiator or is it the radiotor leaking? That was the first time i saw steam coming out during rain.

 

for sure

 

Coming from a part of the country where rain is the default weather, I'd opt for steam from the radiator. Don't remember ever seeing steam coming from raindrops, unless the system is overheating and the radiator is really, really hot.
What year/model? Is rad fan working? AF level down? so many questions, so little time...

 

2003 cooper s.


The fan is working for sure cuz I hear it running sometimes.
My temp gauge never shows anything higher than normal temp.

 

So you saw steam coming out from under your hood and couldn't be bothered to check and see? Do you have 100% antifreeze or is it a mixture of water? Do they salt the roads in your area in the winter. I bet its salty ice melting off your undercarriage.

 

I only saw the steam when I stopped and it was there for less than a minute.

I didn't check because the day before I saw a picture on NAM with steam coming out of someone's grill while it was raining so I thought it was just the rain. -and it was a picture showing his new grill. lol

 

Don't depend on the temp gauge 100%. It 'averages' temp not a direct read. There are some posts on this, I think. When my PS fan went south, the temp gauge did not move off "peachy keen, all OK" until the system started puking coolant all over my clean engine. Grrrr!
