Supercharger Replacement
If supercharger removal is needed, follow the instruc-
tions given in the service manual. Procedures vary based
on engine and supercharger design. Generally, first remove
any parts that will interfere with supercharger removal.
This includes the air plenum, drive belt, wires, hoses, lines,
and throttle cable or linkage, Figure 16-26.
Next, remove the bolts that secure the supercharger to
the engine, Figure 16-27. Free the gasket with light prying.
Then, lift the unit off of the engine.
Superchargers are not normally serviced in the field and
are simply replaced as a unit. However, seal kits are avail-
able that typically include the gaskets, oil seals, and special
oil for the supercharger. These items are easily serviced.
To install the supercharger, use a new base gasket
and apply sealer as recommended in the service manual,
Figure 16-28A. Then, slowly lower the supercharger onto
the engine without damaging the gasket or breaking the
sealant bead. Start all bolts by hand. Then, use a torque
wrench to tighten the bolts in the recommended torque
sequence, Figure 16-28B. Reinstall any accessories and fill
the supercharger with the correct oil.
Finally, reinstall the drive belt and related parts. Start
and warm the engine. Test drive the vehicle to make sure
you have corrected the problem. Make sure the engine has
normal power, does not have abnormal noises, and does
not smoke.
Intercooler Replacement
The intercooler on most supercharged V-6 and V-8
engines is mounted under the supercharger. Once the
supercharger is removed, you can easily access the bolts
securing the intercooler. Remove the bolts and separate the
intercooler from the engine. On some designs, the inter-
cooler is secured to top of the intake manifold. On other
designs, it is secured to the bottom of the supercharger.
Once the intercooler is removed, inspect it for any
signs of coolant leakage. If needed, send the intercooler
