If you recently had your entire cooling system replaced and it’s leaking coolant, it’s either one or two reasons. First and most logical, a hose was not properly attached or is loose. Second and most likely however is that your coolant system may have been filled with either too much coolant, or a higher concentration of coolant to distilled water. Most of the time, coolant sold in stores is a pre-mix 50/50 ratio of coolant to distilled water. However, there are some that are sold as a concentrate (100% coolant). As coolant gets hot, it expands; which can push out of the radiator and coolant tubes into the overflow reservoir and spill from there.
