How long have you driven the car since getting it? If this issue has never occurred before, you can probably eliminate air in the system as an issue. Is your aux fan kicking on? Does this happen every time you drive? The T-stat & W-pump are less likely causes due to recent replacement. Is your belt system operating properly? A failed tensioner or pulley could cause slack in the belt system causing the WP to become ineffective. Check it.
