Removal and installation of the water pump

Before starting procedure performance wait full cooling of the engine.

Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Empty cooling system (the Head of Adjustment and routine maintenance). If the cooler still fresh or is in a satisfactory condition, keep it for the further use.
  3. Remove the fan of system of cooling with a casing (Section Check of serviceability and replacement of the fan of system of cooling and муфты its couplings).
  4. Remove приводные belts (the Head of Adjustment and routine maintenance) and a pulley of the water pump.
  5. Loosen the collars also disconnect hoses from the water pump. If hoses "have become attached", grasp serially each of them more close by the end try повращать it on the union, in case of clearing remove a hose from the union. Try not to damage unions. If hoses are damaged or there was an ageing of their material, cut off them from unions and at assemblage replace new.
  6. On 6-cylinder engines remove a tension roller and the pump of system of hydrostrengthening of a wheel, do not disconnect from the last hoses and establish it aside, a bottom downwards that the hydraulic liquid did not follow.

On 6-cylinder engines in volume of 4.0 l the pump of system of hydrostrengthening of a wheel can be removed in gathering 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 assemblage they should be established on former places. On the models equipped with engines V8 reach flat-nose pliers and ослабьте a collar перепускного a hose over the water pump.

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

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

Installation

 PERFORMANCE ORDER

  1. Clean carvings of bolts and болтовых apertures in the engine block, having removed from them traces of corrosion and old hermetic.
  2. Compare the new pump with old, having made sure of identity of their designs. On models with 6-cylinder engines remove with old наоса the union of a heating hose and transfer it on new, having greased a carving part with hermetic. If the old pump is established on the engine, check up the back party of shovels of a rotor on presence of traces of corrosion. If any of shovels it is lost or strongly corroded by corrosion, replace the pump.

On 6-cylinder engines in volume of 4.0 l with 1993 on 1995 вып. The water pump of reversive type (with return rotation) is established. The rotor of such pumps is usually marked by a letter R. Check the new pump on presence of marks in order to avoid installation on the pump engine not that type that will inevitably lead to an engine overheat.


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

  1. Scratch out all traces of a material of an old lining from a surface of the engine interfaced to the pump.
  2. Wipe interfaced surfaces of the engine and the new water pump the pure rags moistened in acetone.
  3. Grease the surface of a new lining turned to the engine with a thin layer of hermetic RTV.
  4. Grease a surface of the new pump interfaced to a lining with a thin layer of hermetic RTV, then cautiously put a lining to the pump. Pass pair of bolts through fixing apertures of the pump and accurately put on them a lining.
  1. At replacement of the water pump track correctness of installation of various length of bolts.
  1. Cautiously put the pump with a lining to the engine and screw bolts in apertures, having tightened from by hand.
  2. Establish the remained bolts (if they also are used for fastening of arms of any accessories, do not forget to establish these arms at the given stage). Gradually (on 1/4 turns for one approach) tighten bolts with demanded effort.
  3. Establish on the places all acting in film for providing of access to the pump knots and details. Track correctness of a lining tape drive a belt at its clothing on pulleys (the Head of Adjustment and routine maintenance) in order to avoid an overheat of the engine as a result of pump rotation in the opposite direction.
  4. Fill system of cooling and check up correctness of a tension drive a belt (the Head of Adjustment and routine maintenance). Start the engine and make sure of absence of leaks.
