Removal and installation of a radiator and broad tank of the cooling system

Before starting implementation of the procedure wait for full cooling of the engine.


 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Empty the cooling system (The head Nastroyki and routine maintenance). If the cooler is rather new, or is in satisfactory condition, keep it for further application.

Removal and installation of a broad tank of the cooling system

Before starting implementation of the procedure wait for full cooling of the engine.


 PERFORMANCE ORDER

  1. Uncover a jellied mouth of a tank and empty the cooling system (The head Nastroyki and routine maintenance), discharge from a tank all liquid.
  2. Weaken hose collars and disconnect a hose from a tank.
  3. Give screws/nut and remove a tank.
  1. Give the screw with a nut, disconnect a hose (shooters) and take a broad tank of the cooling system from the engine.
  1. You make installation upside-down.

Removal of a radiator

 PERFORMANCE ORDER

  1. Weaken hose collars remove radiator hoses from the unions. If hoses "stuck", grasp them closer by the end with self-locking nippers and try to rotate, then remove them from unions - try not to damage unions the Old or destroyed hoses it is necessary to cut off from unions and at assembly to replace new.
  2. Disconnect a hose of a broad tank from a jellied mouth of a radiator.
  3. Take (having hooked them) two clips of fastening of forward rubber consolidation of a cowl, having provided thereby access to two of bolts of fastening of the top support of a radiator (the panel with the information shilda fixed on it). Give bolts.
  4. Give other bolts of fastening of a support of a radiator and remove a support together with a clamp of the lock of a cowl and the driving cable connected to it. Put a support aside.
  1. Remove a radiator support together in a clamp of the lock of a cowl and put it aside.
  1. Give screws of fastening of a casing of the fan to a radiator and shift a casing towards the engine.
  2. If the car is equipped with AT, disconnect from a back part of a radiator of the line of cooling of transmission liquid (The head Automatic transmission). For collecting the spilled liquid use drain capacity.
  3. Zakuporte of the line and unions.
  4. Give fixing bolts and carefully take a radiator from a motive compartment. Do not allow pouring out from a cooler radiator on the painted surfaces of the car (antifreeze is aggressive in relation to them).
  1. Taking a radiator from a motive compartment, try not to damage its plates about blades and a casing of the fan (arrow).

Installation of a radiator

After removal the radiator can be checked for existence of signs of leaks and damages. If the radiator needs under repair, it should be sent to the specialized workshop or dealer office having the corresponding equipment at the order.

Taking a radiator from the car it is necessary to remember an arrangement and an order of installation of various rubber pillows and sealants (top, lower and side). At assembly all of them have to be established in accuracy on the former places.

Rubber a sealant and the pillows established on perimeter of a radiator and between a radiator and the condenser have to be established at assembly in accuracy on the former places.

Remains of insects and old leaves can be removed from gaps between radiator plates by means of a soft brush or compressed air. Try not to bend plates and not to cut about them fingers. At a purge of a radiator send a current of air only to the party, opposite to the engine.

 PERFORMANCE ORDER

  1. Check radiator support for existence of signs of aging of material of rubber pillows and track that in them nothing was forgotten at installation of a radiator into place.
  2. You make installation upside-down.
  3. After installation fill the cooling system with mix of the required structure (see the Head Nastroyki and routine maintenance).
  4. Start the engine and make sure of lack of signs of leakages of a cooler. Let's the engine get warm up to the normal working temperature that is confirmed by a warming up of the top hose of a radiator. Again check cooler level, in case of need you make having added.
  5. If works are performed on the car equipped with AT, check also the level of transmission liquid, in case of need you make having added.
