Don Knight :

Good morning and welcome to JA.The most common cause for this problem is either a defective water pump or a head gasket problem.You could also have air trapped in the system.When you refilled the coolant resouivor did you fill the rear chamber as there are two chambers in the tank.If you just fill the front part you will have air is the system causing this problem.Please let me know if you need more assistance,Don
