Removal and installation of the water pump

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

Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Empty the cooling system (The head Nastroyki and routine maintenance). If the cooler still fresh or is in satisfactory condition, keep it for further use.
  3. Remove the cooling system fan with a casing (The section Check of Serviceability and Replacement of the Fan of the Cooling System and couplings of its coupling).
  4. Take off driving belts (The head Nastroyki and routine maintenance) and a pulley of the water pump.
  5. Weaken collars and disconnect hoses from the water pump. If hoses "stuck", grasp serially each of them closer to the end and try to rotate it on the union, in case of release remove a hose from the union. Try not to damage unions. If hoses are damaged or there was an aging of their material, cut off them from unions and at assembly replace new.
  6. On 6-cylinder engines shoot a tension video and the pump of system of hydrostrengthening of a wheel, do not disconnect from the last hoses and establish it aside, a bottom down that hydraulic liquid did not follow.

On the 4.0 l 6-cylinder engines the pump of system of hydrostrengthening of a wheel can be removed assembled by an arm - an arm on the water pump.

  1. Give bolts and remove the water pump from the engine. Remember an arrangement of bolts of various length and type - at assembly they have to be established on former places. On the models equipped with V8 engines reach flat-nose pliers and weaken a collar of a perepuskny hose over the water pump.

Details of assembly of the water pump - the 6-cylinder engine (pay attention to location of short and long fixture and do not forget to transfer the union of a heating hose to the new pump).

Location of bolts of the water pump - the V8 engine.
  1. Having reached flat-nose pliers, disconnect perepuskny a hose behind the water pump - the V8 engine.

Installation

 PERFORMANCE ORDER

  1. Clean carvings of bolts and bolted openings in the engine block, having removed from them traces of corrosion and old sealant.
  2. Compare the new pump to old, having made sure of identity of their designs. On models with 6-cylinder engines remove the union of a heating hose from an old naos and transfer it to new, having greased a carving part with sealant. If the old pump is installed on the engine, check back side of shovels of a rotor for existence of traces of corrosion. If any of shovels it is lost or strongly corroded corrosion, replace the pump.

On the 4.0 l 6-cylinder engines from 1993 to 1995 the issue. The water pump of reversive type is installed (with the return rotation). The rotor of such pumps is usually marked with a letter of "R". Check the new pump for existence of marking in order to avoid installation on the engine of the pump not of that type that will inevitably lead to an engine overheat.


The replaceable water pump of the 6-cylinder engine has to be reversive type - make sure available tags in the form of a letter of "R" on a pump rotor.

  1. Scratch out all traces of material of old laying from the surface of the engine interfaced to the pump.
  2. Wipe the interfaced surfaces of the engine and the new water pump with the pure rags moistened in acetone.
  3. Grease the surface of new laying turned to the engine with a thin layer of RTV sealant.
  4. Grease the surface of the new pump interfaced to laying with a thin layer of RTV sealant, then carefully apply laying to the pump. Pass couple of bolts through fixing openings of the pump and accurately put on them laying.
  1. When replacing the water pump track correctness of installation of various length of bolts.
  1. Carefully apply the pump with laying to the engine and screw bolts in openings, having tightened from by hand.
  2. Establish the remained bolts (if they are also used for fastening of arms of any accessories, do not forget to establish these arms at this stage). Gradually (on 1/4 turns for one approach) tighten bolts with the required effort.
  3. Establish all knots and details which were removed for ensuring access to the pump on the places. Track correctness of laying of a tape driving belt when clothing it on pulleys (The head Nastroyki and routine maintenance) in order to avoid an engine overheat as a result of rotation of the pump in the opposite direction.
  4. Fill the cooling system and check correctness of a tension of a driving belt (The head Nastroyki and routine maintenance). Start the engine and make sure of lack of leaks.
