Good for you.
One time, DW was driving home in rush hour traffic. Steam started billowing up from under the hood. She pulled off and called me.
When I got there, with a large tool box, and popped the hood, I saw the lower radiator hose was busted. We got into my car and drove to AutoZone. I bought a pair of radiator hoses, clamps, and some pre-mixed antifreeze. Drove back to her car and replaced both upper and lower radiator hoses. Filled the radiator back up, and followed her home. Never had another problem with those hoses.
P.S. I worked the night shift, so I was in bed asleep when she called me. I got back home in time to go back to bed.
