Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire of the battery.
  2. Merge cooling system (see. Head Routine maintenance of the car). If a cooler rather new or in a good condition, keep it that then to use.
  3. Remove a casing of the fan of cooling (see. Section work Check, removal and installation of the fan of cooling of the engine and coupling of its drive).
  4. Remove driving belts (see. Head Routine maintenance of the car).
  5. Where they are available, weaken collars and disconnect hoses from the water pump. If they became attached, grasp each hose at the end flat-nose pliers for the water pump, softly turn to break hermetic, then remove. If hoses old or worn-out, cut off them and replace new.
  6. Remove fan and coupling assembly, and also a pulley on the end of a shaft of the water pump (see. Section work Check, removal and installation of the fan of cooling of the engine and coupling of its drive).
  7. To remove the water pump, follow the procedure corresponding to your type of the engine.

M10 engines

Give seven bolts (are specified by shooters), and remove the water pump.

M20 engines

 PERFORMANCE ORDER

  1. Uncover the distributor of ignition and wire VV, a begunok of ignition and a dustproof guard (see. Head Routine maintenance of the car).
  2. Where it is provided, remove the distributive sensor (see. Head ignition System).
  3. Remove the top cover of a distributive belt (see. A part the Repair work which is carried out without extraction of the engine from the car).
  1. Weaken all three fixing bolts of the water pump. Give the top and right bolts, but DO NOT GIVE the bottom bolt.
  1. Unscrew the pump down and remove a spring and a pin of a natyazhitel of a driving belt.
  2. Give the last bolt of fastening of the water pump and remove the pump.

Leave a bolt of a natyazhitel strong tightened. Be careful not to shift a cam-shaft asterisk since if valves will start moving, it can lead to serious damages.

M40 engines

Give fixing bolts and remove the water pump. If the pump became attached to a head of cylinders, insert two bolts into special ears in the top and lower part of the pump and evenly tighten them to take the pump of their head.
 

Installation

 PERFORMANCE ORDER

  1. Clear carvings and openings of bolts of the engine to remove corrosion and hermetic traces.
  2. Compare the new pump with old to make sure that they are identical.
  3. Remove all traces of a material of old laying from the engine by means of a special scraper.
  4. Clear interfaced surfaces of the water pump.
  1. On M40 engines establish on the pump a new sealing ring.
  1. Establish new laying on the pump and put forward the pump up to the engine.
  1. Insert pair of bolts into fixing openings of the pump to hold laying on a place.
  2. Accurately fix the pump with laying on the engine, having tightened bolts a hand.

On M20 engines tighten a hand the bottom bolt, then turn the water pump on a place and establish a spring and a pin of a natyazhitel of a driving belt.

  1. Establish other bolts (if they hold also an auxiliary arm, make sure that it by this time is already established into place). Tighten them with demanded effort gradually, on a turn quarter for once. Do not draw them since thus it is possible to deform the pump.
  2. Establish all components which have been removed earlier for ensuring access to the pump.
  3. Fill system of cooling and check a tension of a driving belt (see. Head Routine maintenance of the car). Start the engine and check, whether there are no leaks.
