Inlet Tube

Supercharger System:

REMOVAL
1. Disconnect the inlet tube from the supercharger outlet adapter.
2. Remove four nuts retaining inlet and outlet tubes to intercooler.
CAUTION: The inlet tube must be disconnected from the intercooler so the sealing surfaces and retaining studs are not damaged from bending while removing the inlet tube.
3. Remove nut and push-on nut retaining inlet tube to alternator-power steering pump bracket.
NOTE: To remove the inlet tube in the vehicle, the stud must also be removed from the alternator/power steering pump bracket.
4. Remove inlet tube.

CAUTION: Use extreme care during removal and installation of the intercooler tubes so as not to scratch, nick or contaminate the sealing surfaces.

NOTE: Whenever the outlet tube is disconnected from the intercooler sealing surfaces must be resealed. This is necessary because the existing seal may be disturbed or broken from the unintentional bending while removing the inlet tube.


INSTALLATION
1. Clean and inspect the sealing surfaces of the supercharger outlet adapter intake elbow, intercooler and tubes.
NOTE: Make sure there are no foreign particles on the sealing surfaces of the tubes. It is important that the intercooler tubes seal completely. The engine uses "MASS AIRFLOW" system to calculate fuel flow. Any air leak will cause poor operation and performance.
2. Install gasket sealant tape circumferentially to the spherical seat surfaces of the intercooler tubes. Overlap the tape ends approximately 6mm (1/4 inch).

CAUTION: Do not stretch the tape during installation or the seal may leak.

NOTE: During proper installation, a slight wrinkling will occur on the tape edge at the inner diameter.

CAUTION: The system must be torqued in sequence and to specification for that step. This is required for proper alignment of the system to insure proper sealing of the intercooler tubes.


3. Apply anti-seize/lubricating compound to the inner backside spherical seat surface and threads of the supercharger outlet adapter collar.
4. Position inlet tube, then install upper stud into alternator-power steering pump bracket.
5. Install push-on nut onto stud tight enough to retain tube against alternator-power steering pump bracket surface but free enough to allow tube movement to ensure seating of spherical seat in inlet tube to supercharger outlet adapter.
6. Fully hand tighten the supercharger outlet adaptor collar onto threaded tube end of inlet tube assembly.
7. Install intercooler assembly to inlet and outlet tubes. Install nuts to studs tight enough to retain intercooler and tubes together but free enough to allow movement on spherical seats. DO NOT TIGHTEN AT THIS TIME.
8. Tighten supercharger outlet adapter collar to inlet tube to 200 Nm (148 lb-ft).
NOTE: It is important to tighten the collar to 200 Nm (148 lb-ft) so the gasket sealant tape seats and forms properly to the shape of the sealing surface.
9. Wait 10 minutes minimum and retighten supercharger outlet collar to 200 Nm (148 lb-ft).
NOTE: When first compressed, the sealant tape flows and forms to the sealing surface. If the collar is not retightened, the torque if the collar will drop causing a leak at this joint.
10. Tighten inlet and outlet tube to intercooler nuts to 20-30 Nm (15-22 lb-ft).
11. Install nut retaining inlet tube to alternator-power steering pump support bracket and tighten to 40-55 Nm (30-40 lb-ft).
12. START engine and check for leaks using propane. For procedure
