Removal and installation of the heat exchanger of a heater

The prevention in the beginning see Has undressed Removal and installation of the block of the fan of a heater.


Air central air constantly is under pressure. Do not weaken штуцерные connection of lines and do not disconnect systems any of components before carrying out of its discharge. The coolant should be extorted from system in the special compensatory-regenerative ERA-BLOCK at station of dealer branch or in a specialised workshop of car-care centre. At рассоединении system lines necessarily put on goggles!

Removal

Repair of the heat exchanger of a heater of car Jeep Grand Cherokee is the challenge lying out of limits of qualification of the average mechanic-fan Work it is necessary to make very attentively, without haste. Many of unions and electric sockets of system are deeply under the panel of devices and access to them is extremely limited. For extraction from the car of the block of a heater/conditioner of air it is necessary to remove all panel of devices.


 PERFORMANCE ORDER

  1. On the models equipped with the conditioner of air, make a system discharge (the prevention above see).
  2. Disconnect a negative wire from the battery.
  3. Empty cooling system (the Head of Adjustment and routine maintenance) and disconnect hoses from inlet and final unions of the heat exchanger of a heater.
  4. Remove the console lower a steering column and remove assemblage of the panel of devices (the Head the Body).
  5. Disunite an electric socket of the motor of the fan of a heater (Has undressed Removal and installation of the block of the fan of a heater).
  6. On the models equipped with the conditioner of air, disconnect lines of system from the evaporator on a partition of an impellent compartment. For a detachment of unions special clips are required.
  1. For a stretching of a ring spring at a detachment of lines of a central air it is necessary to take advantage of the special tool.
  1. Remove a broad tank (Has undressed Removal and installation of a radiator and a broad tank of system of cooling).
  2. Remove from a partition of an impellent compartment the processor (РСМ), without disuniting 60-klemmnyj an electric socket.
  3. Delay РСМ far enough to give fixing nuts of the block of a heater/conditioner of air (three behind the processor, one - over the distributor on models with engine V8) from hairpins on the party turned towards the engine to a partition of an impellent compartment.
  1. Give nuts of fastening of a casing on the impellent party to a compartment partition.
  1. Mark and disunite electric sockets of the block of a heater/conditioner of air and resistive assemblage of the motor of the fan. Disconnect a vacuum hose from the vacuum motor.
  2. Remove a drain tube of the evaporator.
  3. Remove a sleeve blowing glasses (over the block of a heater/conditioner of air).
  1. Disconnect a sleeve of heating of back foot wells.
  1. Give nuts from hairpins from the party of a partition of an impellent compartment turned to salon and take assemblage of a heater/conditioner of air from the car.
  2. Give fixing screws and remove the heater heat exchanger, having pulled it vertically upwards from a casing.
  1. The heater heat exchanger is taken from a casing of the block of a heater/conditioner of air.

Installation

 PERFORMANCE ORDER

  1. Establish the heat exchanger in a casing of a heater/conditioner of air and screw screws.
  2. At heat exchanger installation glue a lining for its fixing in the course of installation of assemblage of the fan.
  3. Installation of the remained components make in an order, the return to an order of their removal.

At installation of a casing of the fan/evaporator try not to jam a wire between the case of an air inlet and the panel of devices on the right party of a casing.

  1. Fill cooling system.
  2. Make опорожнение, a recharge and check on leaks of a central air of air (if that is provided).
  3. Start the engine and check up serviceability of its functioning.
