Some coolant are colored and it can range from green blue or pink. At the radiator neck, is there any signs of oil contaminations?

If the punk is clear, then it is the color of the coolant used. If the pink is milky, you could have oil based substances in the cooling syatem. Check the transmission fluid, if it is milky as well, you most probably has a leak in the transmission fluid system, which has cooler/heater core in the radiator.

If transmission fluid is contaminated with coolant, you need to at least replace the cooler inside the radiator and also flush the transmission.
