2001 GMC Sierra 2500 HD Question: new recovery tank did not extinguish low coolant lite

low coolant is constant. I have plenty of coolant in tank. I replaced the recovery tank, but light is still on. -
Answer 1
ON many newer GM vehicles, the low coolant light is controlled by a module that is on the radiator. It has 3 wires and is usually below the radiator neck. Look for it. Also, I would go to www.alldatadiy.com and get a subscription for your Truck, its very reasonable. That way you will have pictures and all the info that you need. Then you will know. -
