2000 Chrysler LHS code P1391 meaning

SOURCE: replaced cracked radiator in 2000 Chrysler LHS but car still overheating. What could be the problem?

I had the same problem. My Chrysler LHS kept overheating. I had the thermostat changed out first and it didn't help. Then I had the water pump changed out and still did no good. Then changed out the radiator, still overheated. Come to find out the people that changed my thermostat put it in backwards. Evidently, the thermostats for these cars look different from all the others and people are not sure how to put them in. I took mine to a Chrysler dealer and they fixed it for me.

fix the radiator first.because coolant temperature sensor need to be in antifreeze.when antifreeze get up to 190 degrees. the coolant sensor act as a thermostat.it resistance decrease then the pcm will command cooling fans to run.if antifreeze low the coolant temperature sensor not going to work. engine is going to over heat.

oh yes you got to love that smell lol just kidding..this car is equipped with a cabin air filter over time it starts getting clogged up and starts smelling..also mice like getting in them and chewing them up and even dying in them try looking for that and see if that solves the problem

glow plugs preheat the fuel to help the engine start.....when its hot outside its not that bad...the colder it gets the harder it will be to start with bad glowplugs..
