Coolant puddle: One sign of a cracked radiator is leaking coolant. The coolant fluid is red or green in color, so if you see a puddle of this under your vehicle, contact a mechanic as soon as possible. The coolant is toxic to both humans and animals so be careful if you have small kids or pets.
Inspect the Radiator and Thermostat. Inspect the radiator for any leaks. Make sure there is plenty of fluid in the radiator. If the radiator has plenty of fluid, but there is no heat in the vehicle, most likely the heater core is the problem. Check the thermostat to ensure it is working properly. The thermostat opens when the coolant flowing through the radiator hits a certain temperature when it is working properly.
