2002 Lincoln LS... ran hot...thru red gauge 3 times in 5 months. All 3 times 5 minutes after start up. 2 of the times start up of luke warm car. All 3 times blows cold air into cabin so I know its not circulating. Last time i released cap on resevoir and heard gurgling (boiling?) water rush into engine.Jumped in and off I went... been couple days and no probs. (Had new thermostat installed after 2nd boil.)
 
Hey,

You could have had air in the cooling system that finally bled out. If thestat is good and the fans are coming on there isn't alot that will cause it to overheat intermittently. You could take it to a shop that has a 5 gas analyser to check the cooling system for Hydrocarbons and Carbon Monoxide. That would let you know if combustion chamber gases are getting into the cooling system and causing a bubble front to cavitate the pump
 
whos doing the work is not very good and guessing to what it is one time in a few years too much to over heat ive had my van five yrs no over heating yet so first let have a look at radiator while cool remove cap fill radiator with coolant fil over flow look for any wet spots check belt and hoses belt should have no signs of cracks or slipping hoses firm to squease then crank motor and watch coolant add more as it needs watch flow til it drops and rises again if it does this thermostat working an dyou can see it open and stuck then we go to driving it so driving it at highway speed like 70 does it heat up then if so radiator about plugged .. if its siting in traffic not moving fan not working right or belt slipping if it heats up fast coul dbe thermo or even wrose head gasket bad and yes it dont have to show signs like stream or oil mixing til it blows out if its in a exhaut side of some parts heat wil go to coolant boiling it out and you might not see it for a long time only way to check is pressure testing radiator could even have radiator boiled out or dip at a radiator shop but checking it out first best just to take it to a shop have th e whole system check
