To access the heads of a 2001 GMC Savana with a 305 engine, begin by disconnecting the battery and removing any belts, starting with the serpentine belt. Next, remove hoses that may obstruct access, including vacuum lines and coolant hoses. Then, take off the intake manifold, followed by the exhaust manifold if necessary, before finally unbolting the cylinder heads. Always refer to a repair manual for specific torque specifications and detailed procedures.
a. Sahara belt b. savana belt
When changing belts, it is important to know the layout and have a diagram to help guide the removal and replacement of these belts. A diagram for these belts can be found in the maintenance manual of a 1989 Toyota Corolla 4-A-F.
the water pump is in with the timing chain, and is very hard to get to. If you will look under your exuast manifold you will see it to change it you have to your manifold off,altinator,belts, balancer,exc just have someone do it
Replacing a CPS can be easy or hard. On the 2001 Gallant 2.4, it is located behind the timing belts. Removal of the main pulley, the covers and the belts is required. This isn't as hard as it sounds and is essentially the same as changing the timing belts. A manual (from Haynes) is helpful. Once the belts are gone, the crank shaft position sensor removal is trivial. Go look in the book and see if you're up to it.
Have you had any belts changed recently? That could be the cause. Turbo wear can cause a whistle as can a leak on the inlet manifold, though a manifold leak usually affects the performance also.
Check for a vacuum leak around the throtle body and intake manifold.
Its located on the lower intake manifold on the 3.9 motor. Its behind the belts, between the two heads.
It is incorrect.
There are two belts on the passenger
Here is a How to/ DIY (do it yourself) for your car. Its for water pump removal, but it shows how to remove the belts, since you have to remove the belts to obviously remove the water pump. http://www.tuningemotion.com/forum/showthread.php?t=2471
The PCV is located on the valve cover either on the front side of the motor ie: by the belts or on the backside under the intake manifold and throttle body....
If it has the 4.3 ltr engine, the intake manifold is notorious for leaking at the back of the engine where you cannot see it. Try using a mirror at the rear of the intake manifold and look for wetness. Replacing the gaskey is the best fix.
