What can fail
A coolant system part like the thermostat, water pump, or fan belt may fail, causing coolant temperature and pressure to rise significantly. If the driver doesn't notice the overheating, coolant system damage could result.
What the fix does
Dealers will install a new radiator cap designed to better manage pressure and allow more coolant overflow during overheating.
