2003 jeep liberty overheating still. Hello, I own a 2003 jeep liberty 3.7l sport and its been having problems ever since i got it. At first i just had to replace the water pump then i had to replace the radiator cause it got cracked, then i replaced the coolant temperature sensor and i thought it would be fixed. Well it was working fine until today i was driving home from walmart and i noticed the temp. gauge going up so i pulled over and there was steam coming from under the hood. so i popped it and the reservoir was spraying steam out the back of it. What's the problem now????

Wherever it was spraying water out of is a leak, a leak in your coolant reservoir is not good, I wouldn't be surprised if the reservoir has a leak...maybe at the seam. It is plastic on these vehicles.
It sounds like your previous overheating problem may have stressed or even damaged other parts that are involved in the cooling process.
Has the thermostat been replaced? It's an inexpensive part, if it's not opening fully, damaged or clogged water will not pass through it as designed to do and cause overheating.
Just my 2 cents as a 2003 Liberty owner, I bought mine brand new and have done all repairs myself and it is still running fine.
