The poor neglected Jeep has had a very small coolant leak since, basically, forever. Ironically, only a few weeks after I actually gave the cooling system a little care and feeding it got a lot less small. The engine ran totally dry and pegged the meter this morning while I was ferrying Landlady to the county road. Fortunately we got close enough that an athletic person could walk the rest of the way, and that part of the road is tame enough that she could come back to the Jeep in a townie car to get her stuff.
Meanwhile I determined that the leak, which appears to be coming from the radiator core, is minor enough that a refill would at least get me home. The second neighbor I called picked up, then more or less dropped what he was doing and came to rescue me. The first neighbor I called called back a few minutes later to see what he was missing.
So I’m home safe instead of fuming beside the road, and that’s why neighbors are important.
