Heater barely wtms up, coolant comes form below the block. Hoses fine, new water pump and gasket. What will this cost me at the shop?

have a good shop pressure test cooling system for you, most shops charge an hr labor to test but they may also only charge you a 1/2 hr if they can determine issue in that time.

could be anything from head or intake gasket or a frost plug have it pressure tested to see where the leak is coming from
it is usually $90 to find the leak
