Always something with older cars.....while hunting for the power steering leak I noticed the coolant level has decreased slightly...again. Maybe losing 3 or 4 oz a month. 2003 Liberty, has 141k on a 3.7L Runs fine, but I did notice some beige droplets in the last of the oil as it drained out, not much. Any typical failure item to look for on these motors? (I'm getting too old to change head gaskets, btw). Thanks.
