OK...so my Jeep Liberty has a few problems that I hope someone might have some insight into. Problem #1 - On really cold days it won't start. We have replaced the battery and alternator but still won't start on some really cold New England mornings. We have to get a boost and rev the engin 2000rpm's for a couple of minutes. Problem #2 problem is that on really cold days the heater does't heat up the car. The engine is running at normal temp but it only blows lukewarm air while driving on highway but on mild days I have to shut off the heat. Problem #3 is that the radio shuts off after running for 20 minutes and now it won't work all together. The radio still functions because on the really really cold morning that we get a boost the radio comes back on for 20 minutes and then starts blinking on and off until it finally quits working altogether. Can anyone help??
Problem 1: buy a system heater to keep the engine warm at night.
You can buy them at any autoparts store . You take your pick from the variety.
Place a light 100 Watt Bulb near the battery but not too close to anything else where it might burn anything.
Problem 2. Check your coolant level to see if you have the proper level. Make sure you have 1/2 antifreeze and 1/2 water if you add any coolant /antifreeze and bleed the colant system. By running the car let it cool, then turn the radiator cap or turn the bleed screw provided on some cars near the thermostat outlet. Then adding some more water and coolant etc.The tightening the cap or bleed screw. When radiator is full. Check the radiator and and remove any debris that may be keeping the air out.
Problem 3. Will get fixed because your battery won't die.

I have a 2002 Liberty and have similar problems. #1 - I have needed the battery jumped twice within last 2-3 months. Battery was replaced a week ago with no issues so far. However my mechanic and place where battery was purchased did not think it needed replacing... #2 - I do not have heating issues #3 Response given to problem 3 does not help in my situation..Radio will shut off after 45-60 minutes during morning commute. It did start-up during evening commute but shut off after 30+ minutes...Now it does not come on at all and the LED clock does not display. It did come back on when vehicle was jumped and after battery replaced.
It appears radio is draining battery somehow... I brought it to a Dealership right after 2nd jump so the radio happened to be working and they couldn't fix something that was working... I got home 10 minutes after leaving and radio stopped working...
Dealership & other mechanic said fuses either work or they don't.
