Alvin1966, hi I looked under the hood, the cap was off the radiator reservior, looks like something splattered all over my motor. No heater or a/c were not on. Doesn't sound like it was on either.
It maybe your vehicle is running hot or there is a A/C or heater hose/line that's ruptured. I suggest taking your vehicle to a trusted mechanic so not to fixing stuff not necessary.
