Hi guys. I installed a water temp sensor last weekend and fearing that I'd caused some air bubbles in the system, I took the reservoir cap off and let the engine run until it got up to temperature and the radiator fans came on. Little bubbles immediately starting coming to the top of the water in the reservoir. This continued (extremely quickly - like 3 every second!) for all of the 15 minutes that it took for the car to turn the fans on. Now, whenever I turn my car on, I can hear it bubbling away! I captured this on my phone (you can hear it bubbling away furiously)... View My Video What should I do?!
