Car Auto Coolant Fluid Level Sensor 93179551 1304702 For Opel Astra Zafira For Vauxhall Astra H MK5 & Zafira B

I had the common Saturn Astra “low coolant” warning whenever I’d start the car, despite a full coolant reservoir. So I replaced this coolant level sensor, but I also cleaned out and shook out the reservoir to be sure that its float moved freely, and I sprayed the new sensor’s connector with electric contact cleaner, all at the same time. At least one of these actions succeeded in getting rid of the annoying low coolant warning.
