No, you can't isolate the rear air from the front air, it's all one system. You would have to fix the leak if you want to keep a/c anywhere in your car.

Good Luck!

Why even with new brake parts in the front and rear on my 2995 Ford f150 2wd truck would front brakes work but not back ? I even put truck on bay lift and hit the brakes and rear just kept spinning.


Bill:

Check your master cylinder. It could be a piece of junk lodged in the fluid port for the rear brake lines, or in the brake line its self. The fact that both rear wheels spin tells me that if it is a clogged line, it is between the two manifolds, (one next to the master cylinder, and the other where the rear brake line splits into two... one for each rear hub. Or it could be that the piston in the master cylinder needs to be replaced. I would disconnect one brake line at one rear wheel and disconnect the rear brake line at the manifold (near the master cylinder)and blow that line out with air pressure. . do not leave the rear brake line connected to the master cylinder as you blow air through the lines as you may damage the master cylinder piston packings. You'll have to bleed the brakes when you are done.

Rear Air Suspension won't air up


take the sensor arm loose and manually operate it, when it is up, it thinks the suspension is low. Spray the bags and hoses with soapy water to find any leaks, dawn dish detergent works well. repair any leaks. If no leaks manifest, take a hose loose and see if you are actually getting air pressure from the air pump. Just because it is running, doesn't mean it is supplying pressure.

Coolant leaks from my ford escape I have had it pressure tested and fitted a new cap When parked leaves a puddle of coolant


Always find the source first, The rear water ports are directly behind the rear lower intake bolts and the front ports are directly in front of the front bolts. The rear ports are cast into the lower intake manifold and are dead ends, air can get trapped in that area. In cold weather your thermostat may open slower, resulting in a pressure build up at the rear ports. Any trapped air will compress. Normal coolant system pressure occurs when the glycol is operating temperature. I would try refilling the system and getting the air out,the leak may only occur when the system is full. With a cold engine, open the radiator cap and add 50/50 mix, fill the resevoir to the low mark. Run the engine with the radiator cap off until the thermostat opens, the upper hose will be hot when the stat opens. Turn the car off and refill the radiator to the top. Sqeeze the upper hose to remove any air. fill if necessary. replace cap, run car again until it reaches operating temp. Now with a full system check for leaks. When replacing lost coolant should also have the heat at max temp. Get a good mirror to check for leaks. The outter mating surface of the rear water jacket gasket is flush with the block and the edge of the lower manifold, sometimes you can see where it blew out.

Heater Core Removal & Installation Front To Remove:
  1. Make sure you have the anti-theft codes for the audio and the navigation system, and then write down the audio presets.
  2. Disconnect the negative cable from the battery.
  3. From under the hood, disconnect the heater valve cable from the heater valve. Turn the heater valve arm to the fully opened position.
  4. When the engine is cool, drain the engine coolant from the radiator.
  5. Disconnect the inlet heater hose and the outlet heater hose from the heater core.
  6. Remove the mounting nut from the heater unit. Take care not to damage or bend the fuel lines, the brake lines, and related parts.
  7. Remove the dashboard.
  8. Remove the evaporator.
  9. Remove the mounting bolts and remove the heater unit. Front heater unit honda-10-00-4128.gif

  10. Remove the self-tapping screws and the clamp.
  11. Carefully pull out the heater core so you don't bend the inlet and outlet pipes.

To Install:
  1. Using care, install the heater core to the heater unit and secure.
  2. Using care, install the heater unit and tighten mounting nuts and bolts to 7 ft-lb (10 Nm).
  3. Install the evaporator.
  4. Install the dashboard.
  5. Connect the inlet heater hose and the outlet heater hose to the heater core.
  6. Connect the heater valve cable to the heater valve.
  7. Refill the cooling system with engine coolant.
  8. Adjust the heater valve cable.
  9. Make sure that there is no coolant leakage.
  10. Make sure that there is no air leakage.
  11. Connect the negative battery cable.
  12. Perform the power window control unit resetting procedure.
  13. Enter the anti-theft codes for the audio and the navigation system, and then enter the audio presets.
Rear To Remove:
NOTE: The rear blower motor, the rear heater core, the blower screen, the rear blower resistor (heating/air conditioning system) and the rear power transistor (climate control system), the rear air mix control motor (climate control system) , the rear mode control motor and the rear expansion valve can be replaced without removing the rear heater-A/C unit.
  1. Remove the self-tapping screws and the clamp, and then remove the bolts and the rear evaporator lines with the rear expansion valve. If necessary, remove the rear expansion valve. Use a second wrench to hold the other fitting on the valve so the rear evaporator lines won't twist. Leave the first fitting loosely connected so you can use it to hold the valve while you loosen the second fitting.
  2. Remove the rear heater hoses.
  3. If necessary, remove the rear blower motor, the rear heater core, the blower screen, the rear blower resistor (heating/air conditioning system), the rear power transistor (climate control system), the rear air mix control motor and the rear mode control motor.

I have a busted rear brake line on my 97 Malibu(V6). Stranded outside city limits. In order to ger into town I need to disconnect rear line at the master cyclinder. Is it the front line for the front...


Disconnecting the line won't stop the fluid from leaking out. Your best bet would be to use a pair of Vise-Grips and pinch the line off where it is broken. You'll probably have to pinch it a couple of times to get it to stop leaking or only seep a little and make sur the pliers are as tight as you can get them usung the square flat part of the jaws to cover the line. Hope this helps.

start from the farthest, right rear, left rear, right front, then left front, take some time in bleeding your left front since it has more air induced during line replacement. good luck!
