1998 Mercury Sable Question: WHY DOES THE COOLANT IN THE RESERVOIR GET HOT AND BOIL OVER AFTER A LONG TRIP
Answer #1csubak30 August 22, 2013, 21:50Master
The engine may be overheating. If the coolant temperature sensor is not working properly, the actual temperature may not be showing on the display.

Above answers are correct. In Florida make sure the radiator cap will hold proper amount of pressure, also make sure you have the 50/50 mix of coolant. I'm assuming this is a 3.0 U engine. These are known for the water pump impellers to wear away. Also make sure the 2 small hoses going to the expansion tank are not clogged.
