the first quad was invented by a greek union who fell off and made it with a quadrall force
chain
V6 3.1 OR QUAD 4 2.3?
ask if its a quad 4 engine IF IT IS RUNS FAST AND FAR WITHOUT THAT CAR ! THE QUAD 4 GM MOTOR IS A LEMON
ON THE 1996 I IT SAYS THEY ARE NEAR OR UNDER THE WATER PUMP
This information should be on the fan shroud.
The timing is ground in the crankshaft and not adjustable.
how do you rebuild 1990 bonneville transmission
Under the engine top cover ( the piece that says Quad 4 or some thing like that)
you have to remove the timing chain in order to remove the cam covers
