So i was Driving in the snow today. I wasn't drifting or doing anything stupid. just driving slowly and carefully and when i pulled into my garage i looked out at my drive way and i noticed little green drops in between my tire marks and it wasnt just a few drops i followed the trail on foot for about 1/4 mile. the drops were spaced out every few feet or so.Should i be worried?

 

Yeah........have you check your coolant level?
You need to see where it is coming from.
Make sure your cap is tight #1. Then start looking at hoses, etc.

 

yeah u need to b worried....coolant is one of the life lines to an engine...like mazurfer said check the cap first and then try to pinpoint where the leak is....be sure that the coolant tank is full and not empty

 

Hmm, it could be that your water pump is going bad. If the seals on the shaft start going out you get a bit of dribble. Take a white clean paper towel and try wiping the area under the water pump pulley (one on the far left with 4 10mm screws). If it is leaking you should be able to tell.

Or if you were driving hard it may just be some blow-off from the pressure cap. Its totally normal and meant to do that.

 

i let my car cool down and i checked the coolant level and it was fine and all my hoses seemed to be pretty tight. My radiator was packed with snow though. could the coolant just have dripped out of my overflow tank?

 

Yeah, if your radiator was blocked then thats likely it was overheating.

yeah if the rad was packed with snow then no airflow was going across it and cause it to start to get hot and some coolant just came out the overflow hose....that is perfectly normal and meant to do that!

 

yea but if it was packed with snow then the radiator wasnt getting hott enough to melt the snow so i couldnt see it overheating kinda weird

 

Well, the radiator wouldn't melt the snow if there was some blockage or failing waterpump to circulate the coolant...

Snow works as an insulator pretty well also. And with the long bottom tray and how the radiator is mounted, its possible that the snow blocked any airflow without being close enough to the snow to melt it.

. . . or it could be something else.

 

I have experienced this green/yellow spotting also whenever my car is in 5 inches or more of snow. After a google search, this is what I found:
An explanation for the yellow snow under your car - The Globe and Mail

Basically it is a chemical reaction between the road salt, water (snow), and exhaust components (zince plating).
