Bolt tightening sequence for water pump 1999 Olds Intrigue

Tighten the long bolts first then the rest of the short bolts. A torque sequence isn't necessary for a water pump.

Ian: According to Chuck on FixYa.com:

Head bolts are torque to yeild so you MUST use new bolts.

Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

1. 20 Nm (15 lb-ft).

1. 40 Nm (30 lb-ft).

1. 50 Nm (37 lb-ft)

Loosen retaining bolts one at a time two to three revolutions and retighten as follows:



Long bolts:

• Tighten to 40-50 Nm (30-37 lb-ft).
  


• Rotate an additional 175-185 degrees.
  


• Go to next bolt in sequence.

Short Bolts:

• Tighten to 20-30 Nm (15-22 lb-ft).
  


• Rotate an additional 175-185 degrees.
  


• Go to next bolt in sequence.

Here is a pic of the sequence

Were to able to torque them all to spec? Did you torque in the proper sequence? If so, you are ok, but if you are still concerned, you could put some locktite on the bolt you feel is a bit lose.

Hope this helps.

Water pump is driven by timing chain idler and is mounted on the rear of the timing chain housing. Disconnect the neg. battery cable. Drain cooling system. Disconnect oxygen sensor connector.
Remove upper exhaust manifould heat sheild. Remove exhaust manifold brace. Remove lower exhaust manifold heat sheild. Loosen manifold to exhaust manifold spring loaded nuts. Remove radiator outlet pipe to water pump coverbolts. Disconnect exhaust pipe from manifold.
Pull down on the exhaust pipe to disconnect it from exhaust manifold bolts. Disconnect outlet pipe from oil pan and transaxle. If equipped with manual tranaxle, remove exhaust maifold brace. Leave lower radiator hose attached and pull down on radiator out look pipe to disengauge from water pump. Leave outlet pipe hanging.
Lower vehicle. Remove exhaustmanifold to cylinder head nuts. Remove exhaust manifold to cylinder head nuts. Remove manifould. Remove timing chain front cover. Remove timing chain tensioner. Remove bolts bolts securing water pump cover to cylinder block. Remove water pump to timing chain housing nuts. Remove water pump attaching nuts. Remove water pump and cover assembly. Separate componets as necessary.
WHEN INSTALLING WATER PUMP MAKE SURE YOU FOLLOW THE TIGHTENING SEQUENCES THAT AFFECT SEALING. My frist one I messed up and broke the pump so becarful.
Installation
If cover was separated from body during removal, join this componets with a new gasket and hand tighten bolts. Apply bearing grease to splines of water pump drive. Set body and assemble into position.
Install and hand tighten bolts securing cover to cylinder block. Install and hand tighten bolts securing cover to cylinder block. Installand hand tighten nuts securing body to timing chain housing. Lubracate outlet pipe "O" ring with antifreeze. (I use RTV) Connect outlet pipe. Install and hand tighten bolts. Tighten bolts and nuts to specification in the following sequence. I'll ad the torque spec. at the end but this is where if you tighten out of order something will break.
pump assembly to timing chain housing nuts.
pump cover to pump body bolts
pump cover to cylinder block bolts (Bottom Bolt First)
outlet pipe to cover bolts
To complete installation reverse removel procedure.
Torque specs are 19 in. or 26mm all except water pump cover bolts which are 124 in or 14Nm
I never torque the bolts just make sure there done in the right order.

On the V8, tighten the bolts, in the sequence illustrated, to 100 ft. lbs. When all bolts have been tightened to this figure, begin the tightening sequence again, and torque all bolts to 130 ft. lbs.

On V6's, tighten all head bolts in sequence to the following torques:
* All except bolts 5, 6, 11, 12, 13 and 14 - 100 ft. lbs.(19-135.5 Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 41 ft. lbs. (19-55.5 Nm)
* All bolts except 5, 6, 11, 12, 13, and 14 - 142 ft. lbs. (19-192.5 Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 59 ft. lbs. (19-80 Nm)

Hope this help (remember rated and commento).

Easy - drain coolant, remove pulley, remove drive belt, remove water pump bolts, reverse.

Check it out at http://99intrigue.shutterfly.com/waterpump

the filler pipe has collapsed ,its need renewing

Either in the center of the tension pulley or on the arm that the tension pulley is bolted to there is a square hole that is the size of the square on a 1/2" ratchet. Take a 1/2" ratchet and stick it in that hole and I think most of them you put it in the tighten position and pull on the ratchet. the tension will release and you can remove the belt.

Good Luck
