Stains on the driveway or on your garage floor are annoying - and indicators of possible service or repair work.
Here's how to decipher them - (bring a rag - you'll need to touch the stain):
Black stain: - it's probably engine oil.
Reddish stain: - it could be transmission fluid.
Greenish stain: If it's greenish or has a greasy/slimy feel on your fingers or feels thinner than motor oil, it may be coolant or antifreeze.
Water: Water that drips beneath the vehicle and dries without leaving a stain is from the AC system and is generally nothing to worry about.
Regardless of the stain's source, it should be inspected immediately. Leaking fluids can reduce their safe operating level, which could lead to greater problems. Tell your J&C technician about the garage or driveway stains and have the vehicle looked at.
How Do I tell a New Stain from an Old One?
Place a piece of cardboard or a paper grocery bag under the engine when you're home for the evening and check it in the morning. A fresh stain on the cardboard or bag, means you'll need to have the vehicle inspected soon.
