I have had a new radiatorput in and a new water pump put in my jeep liberty 2002 I still have to put antifreeze in because of a leak and my heater does not work any suggestions? they said there was a leak in my radiator and whole in my water pump so I replaced those. but antifreeze is still leakin out and my heater does not work.
Re: I have had a new radiatorput in and a new water pump...
You did not say you replaced your thermostat Change the thermostat. Sometimes new thermostats stick. Test the new one before installing by putting it in hot water and watch to see if it opens or closes.
Hi:
You don't need to remove the water pump. The thermostat is located under a housing, at the engine end of the upper radiator hose.
All you need to do is drain your radiator, remove the upper radiator hose, and remove the thermostat housing. Clean it up well, and replace all gaskets before reinstalling!
Well you have 2 heater hoses that contain antifreeze then the top and bottom radiatior hose most likely at the end of a hose where it connects to the motor has a crack on it
Before servicing the vehicle, refer to the Precautions section.
Disconnect and remove the negative battery.
CAUTION
After disconnecting the negative battery cable, wait 2 minutes for
the driver-s/passenger-s air bag system capacitor to discharge before
attempting to do any work around the steering column or instrument.
Drain the cooling system into a clean container for reuse.
Remove the instrument panel by performing the following procedure:
Turn the steering wheel in the straight-ahead position.
Remove the A-pillar trim from both sides of the vehicle.
Remove the top cover from the instrument panel.
Remove the speakers.
Remove the floor console.
Remove the radio.
Remove the center support bracket.
Remove the trim panels from both sides of the inner cowl.
Remove the fuse cover from the junction box.
Remove the instrument panel cluster bezel.
Remove the steering column opening cover from the instrument panel.
Remove the steering column bracket from the instrument panel column support bracket.
Remove the lower steering column shroud cover-to-multifunction
switch screw; then, unsnap both halves of the shroud cover from the
steering column.
Disconnect the instrument panel wiring harness connectors from the following steering column components:
Both lower clockspring connector receptacles
Left multifunction switch receptacle
Right multifunction switch receptacle
Both ignition switch receptacles
Shifter interlock solenoid receptacle
Sentry Key Immobilizer Module (SKIM) receptacle, if equipped
Turn the ignition switch to
ON
position; then, release and remove the shifter interlock
cable connector from the ignition lock housing receptacle.
Turn the ignition switch to
OFF
position; this will prevent the steering wheel from
turning and the loss of the clockspring centering following steering
column removal.
Remove the 4 steering column-to-instrument panel steering column bracket nuts.
Remove the steering column from the instrument panel.
Remove the driver-s side cowl trim cover.
Disconnect the green and light blue wire harness bulk connectors at the junction block.
Disconnect the electrical connector at the inner side of the pedal support bracket.
Remove the 2 bolts from the front and the 2 from the side of the pedal support bracket.
Remove the glove box.
Remove the 2 HVAC mounting bolts behind the center trim.
Remove the passenger trim bezel.
Remove the HVAC mount bolt above the glove box.
Remove the HVAC bolt at the lower outside glove box opening.
Remove the passenger trim cover, disconnect the blower resistor, remove the rolldown brackets at the right cowl side panel.
Disconnect the vacuum check valve and the vacuum reservoir.
Disconnect the blower connectors.
Remove the 4 top bolts connecting the instrument panel to the cowl.
Roll the instrument panel rearward and disconnect the wiring.
Remove the panel.
Discharge and recover the air conditioning system refrigerant.
Disconnect the air conditioning system lines at the evaporator. Plug the openings to prevent contamination.
Disconnect the heater hoses from the heater core. Plug the openings to prevent coolant loss.
If equipped with a manual temperature control system, unplug the
heater/air conditioning system vacuum supply line connector from the
T-fitting located near the heater core tubes.
Remove all remaining fasteners and connections and remove the HVAC unit.
Disconnect all remaining hoses and wires.
Remove the blower motor.
Pop out the grommet on the vacuum supply line and slide hole.
Remove the foam gasket from around the heater core tubes.
Pry off the 4 snap clips that hold the halves of the unit together and separate the unit halves.
Installation is the reverse of removal.
Refill the cooling system.
Connect the negative battery.
Evacuate, charge and leak test the system.
Run the engine to normal operating temperatures. Check the climate control operation and check for leaks.

Also we could send the service manual; confirm us if you are interesting.
you could also be developing a heater core leak. if you start seeing fluid on the carpet or windows fog on the inside when defrosters are on, you got trouble. better to fix the problem now then in the middle of winter.

check level of coolant and check for leaks and unless you wiped clean your engine after doing repair most possible is coolant residue burning off engine
Could be a leak in one of your hoses under the hood, a water pump gasket, thermostat leak or bad heater core. Check under the hood for any signs of leaks. If antifreeze drip onto a hot engine block, you’ll smell it coming in through the vents. If you don’t find any leaks, I’d consider the heater core having an issue possibly.
What does your radiator fill tank look like? When is the last time you changed radiator fluid? If you have an oil leak into the radiator, combination produces a jelly like substance that may be what blocks the screen. You may need a radiator flush and refill.
My best guess would be that you have a bad water pump. When thhey go bad, they will often leak antifreeze from weep holes in the housing. Since your car's heater is nothing more than a small radiator that relies on hot coolant being circulated through it, a bad water pump would explain your lack of heat. Conversely, it may just be a leak. If your system has lost enough coolant, your heating system will suffer the same.

I love my 04 jeep I have replaced the water pump because my anti freeze was leaking..my gasket on my water pump was bad..Then 2 months later again leaking antifreeze,replaced the pump again..then again I ended up having to replace the timing cover because it built up so much pressure that it put pivets in the cover that or because they removed it so many times to replace the pump..thats where i would check first then go from there.
"Mystery leaks" can be very frustrating..You have a leak somewhere, guaranteed. Check all hose connections, hoses, the thermostat housing gasket, the water pump gasket, and the water pump itself (check it last). Try this: park the car overnight inside a garage immediately after driving it while it is still hot. Park it over a large piece of cardboard. Antifreeze is, among other things, oily in nature, and will stain the cardboard where the coolant drips onto it. The areas that get stained are not necessarily the area from which the coolant leaks--water travels along various surfaces until it reaches a low enough spot to drip from, But if you have a stain, even a small one, smell it...if it's antifreeze, check everything again. Sometimes you have a pinhole in a hose so small it is only open and spraying coolant when the system is at temperature and under pressure. Keep looking; you'll find it. If I helped you, please vote/comment, and good luck.
SOUNDS LIKE THE WATER PUMP HAS COME APART..WITH VEHICLE OFF,GRAB FAN (IF EQUIPPED) AND ROCK IT UP AND DOWN..IF NO FAN,GRAB PUMP PULLEY..CENTER PULLEY AND DO SAME..IF IT MOVES ALOT,YOUR WATER PUMP IS GONE..CHECK FOR ANY CUT HOSES,ETC.. ALSO
do you have a "check engine" light on? A bad temp sensor would give a wrong reading. Do you get heat from your heater core? Also make sure you are getting a good flow from catalytic converter and muffler so you know they aren't plugged heating up engine temp. Also make sure all your heat shields are in tact. Are you using 50/50 mix or mostly water? Though in cold temps you normally want to use more antifreeze less water, I would try more water, less antifrezze.
