Bright green fluid on top of the engine.
What can this fluid be? Looks like antifreeze, but this truck has yellowish green antifreeze. Could it be freon or soap? Dealer says its windshield washer fluid, but that fluid is blue in this truck. It is not slippery like antifreeze or soap.

 

Some places use simple green soap to clean dust and dirt.. Maybe they washed it as part of the delivery prep.

 

simple green seems more dark green, this is more of a neon bright green.
