PT Timing Belt

Alors pour changer de la sphère VW...Le PT accuse timidement ses 19866km...un peu tôt pour une distrib recommandée à 96000km...oui mais de 2005...donc 5 ans...faut y passer!

J'en suis pas à ma première distib: VW Golf, BMW 524, Pigeot 309-205, Opel astra, Ford Fiesta...chacun sa procédure mais ça reste en soi identique. Tu découvres la courroie - Tu piges - Tu changes (avé la pompe à flotte, bon ici vu le km, on pourra s'en passer!). Mais si je tenais l'ingénieur de détroit qui a décidé de caser le bloc du 2.4L turbo dans l'écrin du PT, j'ui démontrais bien sa teuté! le compartiment du 2,4 turbo te ferait passer un compartiment de type 3 pour un loft vide...

Juste pour l'exemple, quand il s'agit de détendre l'alternateur...t'as ça:

Le reste est tout pareil, environ 4 h pour extirper un support moteur, avec des vis insortables car elles tapaient dans le longeron en face...

 Sans parler du damper de vilo, qui chantera tout au long de son extraction (3cm d'emboitement serré-serré), heureusement, y'avait l'arrache kivabien:

Alors après avoir galéré une demi journée, je me décide à chercher la procédure Chrysler sur des forums US (parce que les francophones c'est plutôt "j'ai monté seul mes casquettes de phares chromées")

Résultat des courses:

 

Disconnect negative battery cable.

Raise vehicle on hoist. Remove right front wheel.

Remove the right splash shield.

Remove accessory drive belts.

Remove crankshaft damper

Remove the lower torque strut

Disconnect exhaust system from manifold.

Disconnect A/C pressure switch at rear of compressor housing.

Lower vehicle and support engine with a jack.

Discharge A/C system and disconnect A/C lines at coupling block

Remove upper torque strut

Remove screw attaching ground strap to strut bracket.

Remove torque strut bracket from strut tower.

Remove upper radiator support crossmember

Remove power steering pump and bracket. Set pump aside. Do not disconnect lines from pump.

With engine properly supported, remove right engine mount through bolt.

Raise engine with jack until engine support bracket bolts are accessible.

Remove support bracket bolts.

Remove support bracket.

Remove upper timing belt cover fasteners and remove cover.

Remove lower timing belt cover fasteners and remove cover

CAUTION: When aligning crankshaft and camshaft timing marks always rotate engine from crankshaft. Camshaft should not be rotated after timing belt is removed. Damage to valve components may occur. Always align timing marks before removing timing belt.

Before the removal of the timing belt, rotate crankshaft until the TDC mark on oil pump housing aligns with the TDC mark on crankshaft sprocket (trailing edge of sprocket tooth)

NOTE: The crankshaft sprocket TDC mark is located on the trailing edge of the sprocket tooth. Failure to align trailing edge of sprocket tooth to TDC mark on oil pump housing will cause the camshaft timing marks to be misaligned.

Install 6 mm Allen wrench into belt tensioner. Before rotating the tensioner, insert the long end of a 1/8” or 3 mm Allen wrench into the pin hole on the front of the tensioner .

While rotating the tensioner counterclockwise, push in lightly on the 1/8” or 3 mm Allen wrench, until it slides into the locking hole.

Remove timing belt. CAUTION: If timing belt was damaged due to incorrect tracking (alignment), the belt tensioner assembly must be replaced

 

INSTALLATION

 

Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing.

Set camshafts timing marks so that the exhaust camshaft sprocket is a 1/2 notch below the intake camshaft sprocket

CAUTION: Ensure that the arrows on both camshaft sprockets are facing up.

Install timing belt. Starting at the crankshaft, go around the water pump sprocket, idler pulley, camshaft sprockets and then around the tensioner

Move the exhaust camshaft sprocket counterclockwise to align marks and take up belt slack. NOTE: A new tensioner is held in the wound position by a pull pin.

Remove the pull pin or Allen wrench from the belt tensioner.

Once the timing belt has been installed and tensioner released, rotate the crankshaft two (2) complete revolutions. Verify that the TDC marks on crankshaft and timing marks on the camshafts are aligned as shown in .

Install lower timing belt cover and tighten fasteners to 9 N·m (80 in. lbs.

Install upper timing belt cover and tighten fasteners to 9 N·m (80 in. lbs.

Install right engine support bracket. Ensure the power steering pump is properly located in mounting location on bracket. Tighten mount bracket bolts to 61 N·m (45 ft. lbs.)

Lower engine into mounting position and install right engine mount through bolt. Tighten bolt to 118 N·m (87 ft. lbs.).

Install power steering pump and bracket.

Install upper radiator support crossmember

Install torque strut bracket to strut tower.

Connect ground strap to bracket.

Install upper torque strut

Connect A/C lines. Evacuate and recharge A/C system

Raise vehicle.

Connect exhaust system to manifold.

Connect A/C pressure switch connector.

Install crankshaft damper

Install accessory drive belts

Install lower torque strut

Perform torque strut adjustment procedure

Install right splash shield.

Install right front wheel.

Connect negative cable to battery.

 

 

Je me suis épargné la recharge de clim au prix d'un démontage de la transmission gauche...Putain, tu comprends qu'ils te prennent un billet de 1200roros en concession, c'est vraiment pas volé!

et dit donc,
tu aurais pas oublié de parlé du demarrage un peu accélérer
et de ta fuite d'eau qui a fait monté la pression (du proprietaire)
moi j'ai bien rigolé
