possibly head gasket. Check the oil and see if there is any coolant in it.

Check you fan clutch first check for signs of oil around it also check it see if you put on fan blade backwards check to see if they sold you the right water pump some flow in a different direct than others use 1 gallon of anti-freeze then fill the rest with distilled water maker sure yor radiator istoped offalso check over flow tank make sure it has anti-freeze you first want to start from the small stuff first before you start sinking a lot of money in it that you don't have to. Let us know what happens. Good luck! GMC

If nothing seems to work after it warms up have some one watch and as you rev the engine see if you have a collapsing hose
