Question about Buick Cars & Trucks

Open Question

How do I remove complete belt tensioner assembly from 1992 Buick Century 3.3 N engine? Do I have to also remove the water pump?

The lower left mounting hole of the tensioner assembly I'm trying to remove has two nuts on it. After removing the first nut there is a bracket holding the heater hose to the stud bolt. I cannot pull the bracket off to get to the next nut without stressing the pipe coming out of the water pump. Do I have to remove the water pump from the engine block in order to slide that bracket off of the stud? If this is the case I would need to buy both the water pump gasket and the water pump to block gasket?

The bolt holding you up is on the bottom by the compressor, right? You Will have to have an inverted torx socket to remove the studs. Also there is a spacer behind the mount bracket, remember where it goes. You will have to pull the pully bolts and get it out of the way too. Some of those cars have plastic elbows going from the intake to the water pump, be carefull with it. Your motor may not have this but be ready to replace it if it does because it will most likley break. Good Luck.

WHER IS THE WATER PUMP


Try Chilton's or All Data for instructions. This is a 4.5 -5 hour ordeal for a professional and a 2 day mess for an amateur. Plus you must remove the timing belt on the 2.4L 4 Cylinder to get to the pump. Mess up here and you can damage your engine. WATER PUMP is sign with the ITEM 5 in the next diagram...

zjlimited_152.gif


  1. Disconnect the negative battery cable.
This procedure requires removing the engine timing belt and the auto tensioner. The factory specifies that the timing marks should always be aligned before removing the timing belt. Set the engine at TDC on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

  1. Raise and safely support the vehicle to a level that allows access from above and below.
  2. Remove the right inner splash shield.
  3. Remove the accessory drive belts.
  4. Place a drain pan under the radiator drain plug. Drain and properly contain the cooling system.
  5. Support the engine using a floor jack and block of wood, then remove the right motor mount.
  6. Remove the timing belt, tensioner and camshaft sprockets.

WARNING With the timing belt removed, DO NOT rotate the camshaft or crankshaft, or damage to the engine could occur.

  1. Remove the rear timing belt cover to access the water pump.
  2. Remove the water pump attaching bolts.
  3. Remove the water pump.

To install:

  1. Thoroughly clean all sealing surfaces. Replace the water pump if there are any cracks, signs of coolant leakage from the shaft seal, loose or rough turning bearings, a damaged impeller or sprocket, or a loose or damaged sprocket flange.
  2. Install a new rubber O-ring into the water pump.
Make sure the O-ring is properly seated in the water pump groove before tightening the screws. An improperly located O-ring may cause damage to the O-ring and cause a coolant leak.

  1. Install the water pump and tighten the bolts to 105 inch lbs. (12 Nm).
  2. Using a cooling system pressure tester, pressurize the cooling system to 15 psi and check for leaks. If okay, release the pressure and continue the engine assembly process.
  3. Rotate the water pump by hand to check for freedom of movement.
  4. Install the rear timing belt cover.
  5. Install the camshaft sprocket(s), timing belt and tensioner. DO NOT allow the camshafts to turn while the sprocket bolts are being tightened, in order to maintain timing mark alignment.

WARNING Do not attempt to compress the tensioner plunger with the tensioner assembly installed in the engine. This will cause damage to the tensioner and other related components. The tensioner MUST be compressed in a vise.

  1. Install the timing belt covers.
  2. Install the right engine mount bracket and engine mount.
  3. Remove the floor jack and wood block from underneath the engine.
  4. Install the crankshaft damper.
