leak
 

I dont know much about car mechanical stuff. There is a metal rod that connects the 2 front wheels (it has other connections too) which is spirally shaped towards the end (with higher diameter) on either side ( I mean close to the wheel). There is a leak from the spirally shaped part on the left side. I am not sure what that is. is that a oil leak or coolant leak or some fluit ? no idea

It sounds like you are describing the tie rod that goes into the wheel spindle. If it is the tie rod then when the boot tears the grease inside will leak out.

What color is the fluid that is leaking? Can you take a picture?

i dont know the exact color. leak leaves a black spot wherever I park the car

I'm going to go out on a limb here and say it's an oil filter housing leak and dripping on the steering rack... but a picture would help a lot.

thanks. i will try to post the pic tomorrow

Also take a picture of the front of your engine, ok?

That looks like a power steering fluid leak. Have you had to top that off? I hope you are aware that these cars use Dextron III / Mercon Automatic Transmission Fluid (ATF) in the power steering.

Try wiping down the wet hoses and keep a close eye on it for a bit. This way you can get a better look at where the leak is starting from. Also look above the PS pump and see if something else is dripping on it. One more thing... does the fluid on the hoses look and smell like motor oil? Atf is red. You can see it clearly if you wipe it off with a white paper towel.

A common failure when it starts getting cold is the oil filter housing Oil can drip down from there, too.
