Replacing a car pump is an extremely difficult operation that will require a lot of your time and effort. Therefore, if you are not sure of anything, do not do this work yourself, but agree with the masters at the car service. As a rule, it is required to change the pump when, during its operation, a bearing noise appears or a coolant leak is detected through the control hole.
Necessary
- - assistant
- - pit or lift
- - head on "10"

- - hexagon to "5"
- - Phillips screwdriver
- - "Torx T-30" wrench
- - key to "10"
- - head on "17"
- - large slotted screwdriver
- - spanner or head on "15"
- - spanner wrench on "17"
- - side cutters
- - sealant
Instructions
Step 1
Remove the engine protection (if you have it installed) by unscrewing the five nuts with the head on "10".
Step 2
We drain the coolant from the system. We take a wide container with a volume of at least 6 liters and substitute it under the drain hole made in the lower part of the right radiator tank. Unscrew the radiator drain plug by hand.
Step 3
We drain the coolant from the engine cooling jacket. To do this, we substitute the container under the drain hole located on the front side of the cylinder block, closer to the clutch housing. With the key on "13" we unscrew the drain plug of the cylinder block.
Step 4
After the end of draining the liquid, we wrap the drain plugs of the radiator and cylinder block.
Step 5
Remove the timing belt, timing belt tensioner and support rollers. Using a "5" hexagon, unscrew the five screws securing the front upper timing cover.
Step 6
Remove the right mudguard in the engine compartment. Use a Phillips screwdriver to unscrew the self-tapping screw that secures the flap to the fender liner. Then, using the "Torx T-30" wrench, unscrew 2 self-tapping screws for fastening the flap to the body and 2 self-tapping screws for fastening to the mudguard of the power unit.
Step 7
We continue to remove the timing belt. Now turn off the two screws securing the front lower timing cover with a "5" hexagon and remove the cover.
Step 8
Now we need to remove the alternator belt. We loosen the tightening of the nut securing the generator to the upper bracket and turn the adjusting bolt counterclockwise with a key "10", decreasing the belt tension. Then, sliding the generator to the cylinder block, remove the belt from the generator pulleys and the crankshaft.
Step 9
Now we unscrew the alternator pulley bolt using the head on "17". An assistant must secure the flywheel during this operation by inserting a large slotted screwdriver through the hole in the clutch housing between the flywheel teeth. This is necessary so as not to knock out the valve timing. Remove the alternator pulley and its support washer.
Step 10
Using a spanner wrench or a "15" head, loosen the timing belt tension roller bolt. This will release the timing belt tension and you can remove it. We unscrew the tension roller mounting bolt and remove the roller.
Step 11
Using a spanner wrench on "15", unscrew the bolt securing the timing belt support roller and remove the roller assembly with a bolt and a thrust washer.
Step 12
Now we need to remove the phase sensor (or camshaft position). We remove the "-" terminal from the battery and, with the IGNITION OFF, be sure to squeeze the lock of the wiring harness of the engine control system. Disconnect the wires from the sensor. We take the head on "10", unscrew the two mounting bolts of the sensor and remove it.
Step 13
Now we need to remove the camshaft pulleys. Using a spanner wrench on "17", unscrew the bolt securing the toothed pulley of the inlet camshaft valves, keeping the pulley from turning with a screwdriver or other device. We carry out a similar operation with the toothed pulley of the exhaust valves.
Step 14
We unfasten or bite with side cutters two plastic clamps securing the wiring harness of the engine control system to the rear cover of the timing drive and remove the wires from the cover.
Step 15
Using the "10" head, unscrew the 6 bolts securing the rear timing drive cover, remove the cover from the engine and raise it. Now we unfasten or cut with side cutters the plastic clamp that secures the wiring harness of the engine control system to the bottom of the rear timing case cover. Then remove the cover.
Step 16
Now let's move on to the pump itself. Unscrew the three screws securing the pump with a "5" hexagon. Using a slotted screwdriver, we pry it by the tide on the body and remove it from the cylinder block socket.
Step 17
Before installing a new pump, clean the cylinder block mating surface from the old gasket. Apply a thin layer of sealant to both sides of the new gasket and glue it to the cylinder block. We install the pump only in one position - with the control hole in the body down.
Step 18
We install all the details in reverse order. Do not forget to add coolant!
