Car is making bubbling/ boiling noise when i turn it off but not smoking nor do i see any leaks. Just recently changed raditor and the thermostat and changed the water pump couple months ago!
Boiling coolant suggests that the cooling system a) isn't holding pressure, or b) isn't full, and/or c) isn't cooling.
a) could be caused by a faulty radiator cap or coolant overflow tank cap, or a leak in the cooling system that you haven't seen. b) could be caused by not filling the cooling system completely, so that air remains inside; some cars require filling in non-intuitive ways. c) could be caused by a water pump failure (even new pumps fail), a failure of the pump's drive belt to actually drive the water pump shaft, a clogged radiator, and/or a failed thermostat.
