Do i have to put coolant into the radiator or can i put it in the reservoir? My car is out of coolant and over heated today. There is no coolant in the reservoir and someone told me I have to put it straight into the radiator and drain it first. But someone else told me I could put it in the reservoir.
A 50/50 mix of liquid or coolant is usually sufficient. Some coolant recovery systems are pressurized and have a radiator pressure cap instead of a normal cap. Some older vehicles have no coolant reservoir, so to check and add coolant, you have to open the cap on the radiator. Never add coolant to a hot engine!
