Can I replace the radiator on 2007 Impala without removing AC coolant hoses? If not, how do I remove and replace the AC coolant?

It is NOT necessary to remove the "A/C Radiator" (condenser) to replace the radiator. The condenser is mounted in FRONT of the radiator and the radiator is removed from the rear.

  • Drain the coolant from the radiator.
  • CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Always drain coolant into a sealable container.
  • Remove the engine mount strut. Some technicians will disconnect just one and swing the strut out of the way. In this case, loosen the through bolts to prevent shearing the rubber bushings when the strut is moved out of the way for radiator removal. In some cases, it is best to remove the strut and its mounting bracket completely.
  • Separate the cooling fan harness connector from the engine harness.
  • Separate the low coolant level module harness connector at the module.
  • Disconnect the radiator hoses.
  • Remove the cooling fan assembly from the vehicle.
  • Disconnect the automatic transaxle cooling lines from the radiator
  • There should be two small retaining brackets at both ends of the radiator that are removed.
  • Carefully lift the radiator up and out of the vehicle. Note that the bottom should have locating pins on each end which should fit into grommet-like rubber mounts at installation.

    How do I change engine cradle

    First you would need to support the engine with a front wheel drive designed "engine support craddle" You will need to find at least two areas of the engine, right side front and left side rear or visa versa that can be used to mount the chains or brackets to support the weight of the engine safely. You can purchase a cheap engine support craddle for front wheel drive vehicles at your local auto parts supplier. It is really not too difficult to do but depends on what service you are going to perform on the vehicle. ie: craddle damage or transmission work ? The craddle usually supports the engine by using the inner edges of the front fender mounting areas and front radiator support and cowl inner lip area. Good luck !

    Change thermostat on 1998 toyota camry

    1. Write down your radio code if it has some anti-theft device.
    2. Allow the engine to cool down for about 3-hours before the start of this operation.
    3. Open the hood, and disconnect the battery negative terminal. Tuck the negative terminal aside so it won't flip back.
    4. Locate the radiator drain-plug (plastic wing-nut) on the lower back side of the radiator, and turn it backward to remove it.
    5. Place a container under the radiator to catch the anti-freeze coolant.
    6. Remove the radiator cap.
    7. Once the coolant is drained, trace the upper radiator hose to where it ends on the engine(thermostat housing), and remove the hose with a medium size plier.
    8. Loosen the three bolts holding the thermostat housing. Gently take out the housing.
    9. Notice the position the thermostat was previously installed.
    10. Replace the old thermostat, and the o-ring around it. Clean its mounting area. Notice that the o-ring fits around the thermostat.
    11. Replace the thermostat housing and torque the three bolts to 78-inch pounds. Replace the upper hose.
    12. Replace the radiator drain-plug.
    13. Re-use the antifreeze coolant and be careful no dirt goes in with the coolant into the radiator.
    14. Return the radiator cap.
    15. Reconnect the negative battery terminal.
    16. Start the car and check for leak.

    Important: Anti-freeze coolant harmful to the environment. Return unwanted anti-freeze coolant to collection areas.

    2000 impala the air controls all work properly the air just will not get hot

    The first thing to check when this happens is the thermostat. They are about $10. They are located on the engine at the beginning of the lower or upper radiator hose. They are usually mounted inside a round, bowl shaped housing. It blocks the coolant from getting out of the engine until the engine is up to operating temperature. If it's stuck open, the engine will never reach operating temperature in cold weather. Does the temperature meter on your instrument panel get up to the normal area? If it stays down on the cold side, I would say that confirms this theory. If the engine gets up to normal temp, there may be something wrong inside the heater box. There may be a flap that is not opening or closing. If that is the case, a seasoned mechanic will need to take a look at it. Hope this helps.
