Removal and installation of the heat exchanger of a heater

Cars considered in the real Management are equipped with system of additional safety of SRS which is better known as a safety cushion. Before performing any works near assembly of a pillow or a steering column, without fail disconnect system in order to avoid receiving traumas as a result of its casual operation (see. Head Onboard electric equipment). Isolation and contact sockets of electroconducting of a chain of SRS are painted in bright yellow color. It is not necessary to connect any diagnostic devices to this chain!


Air central air constantly is under a high pressure. At all do not disconnect refrigerator lines and do not remove any components of system, previously without having executed a discharge of the last. The discharge of central air of air should be made by strengths of the skilled expert in the conditions of a car-care center workshop. At a rassoyedineniye of refrigerator lines surely put on goggles!


Do not allow antifreeze hit on open sites of a body and the painted surfaces of the car. Casually got splashes immediately wash away a plentiful quantity of water. Remember that antifreeze is extremely toxic liquid and its hit in an organism even in small amounts is fraught with the most serious consequences (up to a lethal outcome). Never leave antifreeze being stored in leaky closed container and immediately collect cooling liquid spilled on a floor. Remember that the sweetish smell of antifreeze can draw to itself attention of children and animals. About ways utilization of the fulfilled cooling liquid consult at any station of car-care center. In many regions of the world special points on different reception of working off are equipped. At all do not merge old cooling liquid in the sewerage and on the earth! Recently nontoxical grades of antifreeze are developed, however they also are subject to utilization in the organized order.


Before starting procedure performance, wait complete cooling of the engine.

Removal

 PERFORMANCE ORDER

  1. Empty cooling system (see. Head Routine maintenance).
  1. In an impellent compartment disconnect heater hoses from heat exchanger branch pipes — previously mark hoses for the purpose of a guarantee of correctness of their connection at assembly.

Firm hoses are equipped with sockets of fast joining.

  1. In the presence of access to a source of the compressed air, blow the heater heat exchanger for the purpose of removal of the remains from it cooling liquid in order to avoid hit on a salon carpet at heat exchanger removal. Connect to one of unions of branch pipes a hose which second end lower in suitable capacity. To the free union submit air, - in the absence of access to a source of the compressed air muffle unions.
  1. On equipped In models cock the parking brake, поддомкратьте a front of the car and establish it on props, at the corresponding complete set remove protection of a case. Remove a back support of the engine (see. Head Engine).


  1. Turn out two fixing bolts and remove from the floor panel intended for removal of condensate drainage knot.


Dismantle of drainage knot is possible and without preliminary removal of a support, however work thus essentially becomes complicated.

  1. Remove the central console (see. Head Body). Extend forward and remove sleeves of supply of air in back foot wells.

On the Zafira models before removal of air lines give bolts of fastening of racks.

  1. Release 9 clamps of fastening of a cover to the main case of a heater. Pay attention that on some models besides clamps are used also two fixing bolts.
  1. Lower a cover.
  1. On equipped In models disconnect electroconducting from the valve of an otsechka of cooling liquid.
  1. Release fixing collars and disconnect hoses of an okhladitelny path (model without To/in) / the otsechka valve (models with To/in) from the heater heat exchanger.
  1. Take the heat exchanger from the heater case.
  1. Remove sealing rings, - at installation of a ring are subject to replacement without fail. Check a condition of sockets of fast joining, - defective components replace.

Installation

Installation is made as it should be, the return to an order of dismantle of components.

 PERFORMANCE ORDER

  1. Before installation grease new sealing rings with a small amount of silicone greasing. On the Zafira models track reliability of landing of hoses on the unions on a partition of an impellent compartment, - at connection of hoses support them the hammer handle.
  2. In summary make filling of system of cooling (see. Head Routine maintenance). Check reliability of fixing of shtutserny sockets of fast joining, - the green lock ring should be planted freely.
