Renault Grand Scenic Dephaser and Cambelt Change. 2.0VVT

Before you start

• • Please don’t attempt this job without the cam/crank locking tool. The proper tool is a really tight precision fit.

There are no key-ways on the crank or cam pulleys so unless the crank / cams are locked the timing will be lost.

1. Unclip plastic cover and remove rubber seal 2. Unscrew and remove wiper arms

1. Remove wiper motor and linkage. There is 1 connector at the back of the wiper motor

1. Unbolt and remove metal cover to reveal the engine

1. Remove wheel and wheelarch liner. 2. Jack car up as shown. Note use of trolly jack under sump to support engine. Use wood block.

(Not shown – Remove the fan belt 15mm socket on long bar and pull down on tensioner.)

1. Remove throttle butterfly (4 bolts and 1 connector). This is on a rubber seal behind. When refitting put a light smear of RTV sealent to ensure a good seal.

2. Then remove 2 rubber core plugs on the end of each cam. 1 is hidden behind throttle butterfly. Punch a screwdriver through the middle and prise out. Dont try and put the cam lock tool in yet as its a very tight fit so you need to lock the crank first.

1. Looking from the top of the dipstick down the front of the engine use a couple of tie-straps to lift the water hose up and out the way.

2. Follow the dipstick down to where it goes into the block. Just to the right is a bolt (See next slide). Undo the bolt 3. Insert the crank pin. Turn the crank until the pin fully locates. This is TDC on No1.

1. Crank pin bolt in more detail. You’ll need an E16 socket. Its tight and a pain to get to.

1. Back to the cams now. The cam lock tool should now slide into the slots at the end of the cams. Its a very tight fit.

2. The locking pin for the tool slots into a notch on the head.

1. Remove the cam belt cover. This this one of the easiest I’ve come across to remove. Top half is alumnium and held with some 10mm bolts, lower part is plastic with 3 x 6mm bolts. All are easy to access if you jack the engine up and down to utilise the gaps in the inner wing.

1. 12mm allen key to remove the cap on the end of the dephaser. There will be some loss of oil.

Note that there is a copper washer behind this cap. Leave the cambelt on for now to give extra support to holding the cams in place.

1. Now you can remove the main bolt. The pulley just pulls off. No keyway

1. Losen cam belt tensioner and remove cambelt

To replace the belt, put the dephaser back on but leave it loose and free to rotate. Put the cambelt back on but keep the tension on the right hand side. When the belts back on you can torque to pulley bolt. I put mine on to 90lb, and because I used the correct locking tools everything stays lined up.

Putting everything back is simply the reverse process.
