2001 Jeep Cherokee Deer collision- radiator and other repai

Besides repairs to all front-end damage, what has to be checked completely when deer collision knocks out radiator and cooling system and can water pump, timing belt and other sytem parts, etc, be damaged and in need of repairs? Insurance Co, refuses to replace water pump-- it is making a noise which was not present before the deer collision. HELP! Give me a brief summary of what to demand that has to be checked and replaced. Impact was such that even part of front seat brackets were damaged? What other areas of front-end and engine have to be checked/rerpaired?
