Yes a special tool is needed but better to have amechanic do it as they have experience in what to look for. You dont'

You need a coolant pressure tester for your car then you pum p it up to about 20lbs on gauge and see if it goes down. If there is a leak you can look at allhoses, connections etc. Ifyou see no leakage it is either a head or intake gasket leaking internally.
