I'd check the lower radiator hose where it attaches to the engine and the heater hoses. Both are in that area. Double check those elbows too. If the O rings aren't lubricated with at least some coolant before installation they can roll back onto the elbow and not seal. I use WD 40 to lubricate the O rings before installation. Did you make sure you got all the old water pump gasket off? Did you use gasket sealant on the new water pump gasket? Hope that helps! Jim
