Water pump.


Does your vehicle have the cap on the radiator or on the over flow tank ? If cap is on the radiator or if it's on the over flow tank just leave cap off and fill to fill line with anti freeze let vehicle run with cap off until vehicle reaches normal operating temperature once t- stat opens add more anti freeze to fill level and put cap back on. If cap is on radiator fill with anti freeze until you can see anti freeze. Follow same instructions as above. Now some vehicles will over flow anti freeze from radiator while its reaching operating temp but that is normal. They do make a tool that is like a bucket attaches to radiator for that problem. Hope this helps
