I replaced the coolant reservoir hoping to get rid of the low coolant message but unfortunately I still have the message. This was done at same time as water pump. So did I not get the connector hooked back into the new reservoir well enough? It is possible the new tank which I got from Atlantic British is faulty? I ran the truck to bleed the system. Could it take a few more start ups to get the message to go away. Do I still have air in the system and that’s why message is persistent. Clearly I can see I have plenty of coolant . Where to go from here .
