Leaks and Pains
Not trusting my seal repair on the refrigerator, Mike devised an ice cube freezer alarm using a volt/ ohm multimeter with an audible alarm. Keeping the probes separated, he placed them into salty water [B] and put the water in the freezer; the meter itself stayed outside. If the fridge died, the ice would melt, and the electrical resistance would drop enough so the meter would sense continuity between the probes — and the buzzer would sound. “I wouldn’t stake my life on it,” Mike said, “but I’ve seen it work.”
With that set, we finally got under way. It was smooth sailing too, until the engine’s overheat alarm sounded. We were losing water from the closed cooling system but couldn’t find the leak. Then Mike remembered seeing white smoke (steam) coming from the exhaust, which probably meant a leaky head gasket. as a quick fix, I tried to seal the cooling system with crushed pepper. Pour a handful into any coolant-access point, such as the plastic reservoir near the pump, and let it circulate. as the fine grains get drawn into the leaks, they (temporarily) seal them.
We topped off the system and made it another few hours until the next disaster — a cracked exhaust hose. To patch the hose, we used the classic soda can hose repair. Wrap the leaky area in a rag. Cut the ends off a soda or beer can, and cut the can lengthwise. Wrap the can around the rag and secure it with at least four small pieces of rope tied with constrictor knots for optimum leverage (duct tape doesn’t squeeze hard enough, and zip ties can melt) [C].
