common causes for the car to over heat can be boiled down to a few things (pardon the pun)
-bad radiator, but usually leaks when it is bad or when it is clogged both top and bottom hoses are not the same temp
-bad FAN, will cause air not to flow over the radiator thus not cooling it
-bad ect sensor aka engine temperature sensor, self explaitory what it does. a bad one will show that it never gets above the 4:00pm position at normal temps then shoots to HOT. cheap $30 swap out
-bad coolant bottle cap, cant hold pressure
-blown headgasket. pop the coolant bottle off and smell inside if it smells like exhuast or fuel you done. another check is oil dipstick check for choclate milkshake.
-bad water pump can cause overheating too
refund? not likely since they did change it with working components. most mechanics aka parts changers/fortune stealers/guessers are great at spending your money to fix the problem.
to properly help you, we would need more info.
-is the top and bottom hoses hot when the car overheats?
-where is the coolant coming out from?
-engine temps before the overheating, does it ever get over the 4:00pm position, normal is 3:30
-cooling fan kicking in when AC is turned on?
-color of coolant tank cap? brown is old one, green is new style one.
