Hi. Driving along on a beautiful autumn weekend afternoon. 10 miles in, all warning lights begin blinking off and on. Exited highway. Rattling noise began, increased to considerable intensity. Smoke began spewing from left side of hood as I was facing it. Pulled over. Opened hood. Huge splash of liquid all over. Water? Dark enough to be oil. Radiator looked okay, hoses, but I am not mechanical. Tow driver guessed water, but the loud rattling sound as he started engine to drive onto lift seemed of concern. Will get diagnosis Monday from mechanics. Meanwhile, can anyone guess what this was? Only problems waiting for fix are power steering rack and pinion, and overdrive troubles. Thanks for any opinions.
