I just did one on a Dodge Charger. On the coolant system the radiator, thermostat, and quite a few components were named. However, this car had a plastic coolant outlet that runs underneath the upper intake leaking. Guess what, since the coolant outlet wasn't named it wasn't covered. Most car may not even have coolant outlets like thjis but these warranties are written to cover ever make of vehicle. Truth is a good warranty would have covered this problem because it was definitely a defect and failure in the coolant system but it was not covered,
