    I have a 2000 Grand Jeep Cherokee with the inline 6. I replaced the water pump, and it still gets

    Over 210 degrees when in stop and go conditions. Plus my heater is barley working at all. Any suggestions???

    Got any coolant in it?  How much over 210?

    Some possibilities:

    Typical Diagnostic Tests:

    Check Belts and Hoses
    Visually inspect exterior Radiator rods for leakage (Corroded Fins by coolant - will appear like green stains) Inspect interior for corrosion blockage of fins
    Radiator Flow (Check flow for blockage & check thermostat opening operation)
    Fan operation (Possible failure Temp sensor / Fuse / Fan motor)
    Check for all leaks (Pressure test system)
    Radiator cap not holding pressure - Test
    Combustion leak (Block check system)

    Preventative maintenance measure w/ water pump replacement is to replace thermostat (To test means removing, so go ahead and replace)

    Coolant measures:
    System needs to be flushed?
    Coolant 50/50 Mix with water
    System needs to be purged of air
    Coolant level

    I hope this helps
