Question about Cars & Trucks

1 Answer

1997 Pontiac Bonneville While trying to take the intake manifold off to replace the gasket the belt tensioner broke and its not something simple like a bolt or anything, its where the bracket for it connects to another bracket, from what I can tell. Its like a circular plastic piece that was either pressed into place or maybe bolted on, I can't tell. Is there any simple solution for this? Or will I need to replace the tensioner?

SOURCE: 1999 Pontiac Bonneville serpentine belt installation.

if you look by the crankshaft pulley to the right you will see a tubular looking shaft about 1" diameter , you will notice you can't get the belt out from under this piece , it has a nut on it , once you take the nut off , you will notice it has a star shaped point on the tip of the stud , it requires a reverse torx socket or wrench to remove the stud , when you get the stud out the tube piece it can be removed , then the belt comes off , replace the belt , now comes the tricky part , fitting that tube spacer back into its spot , it can be difficult , once its in place put the stud back in , and put the nut on and tighten it , your pretty much a pro now . thanks.

SOURCE: how to remove belt tensioner???

you need a long bar... the kind with a 3/8 inch socket head that goes into the opening in the tensioner and you move it that way to loosen it so you can get the belt off... then undo the three or so bolts holding the tensioner on... you will probably need a vise to hold it when you take the bolt off for the pulley. replace the pulley and bolt it back on...

Pontiac bonneville 3.8 vin code k . I replaced the in take gasket because it was leaking water between the top an bottom intakes going into the cyclinder heads its still leaking after all this work ive...


This is the entire task for it. It sounds like you might not have torqued it correctly, or your intake is cracked. But take a look at all of the info:

VIN K Engine On these engines, the upper and lower intake manifolds must be removed separately.
  1. Properly relieve the fuel system pressure, as outlined in Section 5 of this manual.
  2. Disconnect the negative battery cable.
  3. Drain the cooling system into a suitable container.
  4. Remove the fuel injector sight shield and air intake duct.
  5. Tag and disconnect the spark plug wires on the right side of the engine and position aside.
  6. Remove the manifold vacuum source.
  7. Remove the fuel rail.
  8. Remove the EGR heat shield.
  9. Unfasten the cable bracket-to-cylinder head mounting bolt.
  10. Disconnect the throttle cable.
  11. Remove the throttle body support bracket.
  12. Unfasten the upper intake manifold bolts, then remove the upper manifold.
This engine has two bolts which are hidden beneath the upper intake. These bolts are located in the right front and left rear corners of the lower intake manifold. This is why it is necessary to remove the upper before servicing the lower manifold.
  1. Disconnect the upper radiator hose.
  2. Remove the alternator, as outlined in Section 2 of this manual.
  3. Remove the drive belt tensioner.
  4. Remove the EGR valve outlet pipe.
  5. Unfasten the intake manifold bolt, then remove the manifold from the vehicle. Remove and discard the gaskets. Thoroughly clean the gasket mating surfaces, intake manifold bolts and bolt holes.
To install:
  1. Position a new gasket, then place the lower intake manifold over it. Apply a suitable threadlocking compound to the bolts, then install them. For 1995 vehicles, tighten the bolts twice, to 88 inch lbs. (10 Nm), in the sequence shown in the accompanying figure. For 1996-97 vehicles, tighten the bolts to 11 ft. lbs. (15 Nm), in the sequence shown in the accompanying figure.
    1. Install the EGR valve outlet pipe.
    2. Install the drive belt tensioner.
    3. Install the alternator.
    4. Connect the upper radiator hose.
    5. Position the upper intake manifold on the lower manifold. Install the retaining bolts and tighten to 89 inch lbs. (10 Nm).
    6. Install the throttle body support bracket, then connect the throttle cable.
    7. Install the cable bracket-to-cylinder head mounting bolt.
    8. Install the EGR heat shield.
    9. Install the fuel rail.
    10. Install the manifold vacuum source.
    11. Connect the right side spark wires on the right side of the engine.
    12. Install the fuel injector sight shield and air intake duct.
    13. Fill the cooling system with the proper type and amount of fluid.
    14. Connect the negative battery cable. Start the engine and check for leaks. Check the cooling system, and add as necessary.

A serpentine belt tensioner. Tell the parts person the year, make, model and the engine size. They will know what to get you. Open the box to make sure it comes with the appropriate gaskets. Hope this helps. Good luck

Water on top end of engine below intake cover


This may not help, but my 1990 Ford Bronco has a small coolant line running through the throttle housing,(which I bypassed after the metal pipe broke)- "IF" you have a similar setup, maybe it is cracked on the interior and leaking in that way.
