Worked on leaking heater hose this morning.
I taped a line to my $29.17 NAPA 5/16th wrench in case I dropped it while tightening the hose clamp. Without this line the wrench would have fallen into the engine several times.
Tightened the clamp nut about 30 degrees of a full turn. Run the engine up to full temperature and no leak. After the engine cools down I will see if I can get a little more of turn on the nut, after I get the wrench on the nut i have just my finger tips as turning leverage.
