On my I4 swap, with a brand new coolant level warning module installed, the first coolant gauge I installed had an intermittent lingering blinking coolant light; if I left the bus sitting for a few days, after starting the bus the light would stay on for a period of time then go out. If bus driven daily, this didn't happen. This gauge was 25+ years old from a higher mileage 1985 1.9; a failing coolant level warning light capacitor is to be expected? I replaced this gauge with one from what was likely a lower mileage diesel. This gauge has been reliable. On a recent trip in my I4 swap bus, while coasting down a long steep mountain pass in Oregon, the coolant level warning light did exactly what it was intended to do. It warned me of a low coolant situation. Due to a certain level of engine swap arrogance on my part, and past gauge history, I assumed the gauge was at fault, so keyed the ignition on/off while driving. The light went out, but then came back on. Indeed there was a coolant loss happening. Image showing cause of the coolant loss (albeit a VERY slow leak) on the Jetta coolant expansion tank installed in my swap: http://tinyurl.com/p5pg5ex I imagine this type of failure can happen on the WBX expansion tank? I digress. IMO, age of the part not withstanding, the coolant level warning light in the Vanagon coolant gauge works as the VW engineers intended. ;) Neil.
