What’s that sight?

Driveway Stains

Stains on the driveway 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 slightly greasy/slimy feel on your fingers or feels thinner than motor oil, it may be coolant/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 ACDelco trained technician about the driveway stains and have the vehicle inspected right away!
