7. Use plastic ties (BP-46) to secure hose in position and away from potential damage. Trim ties with
side cutter.
Note:
Over tightening the plastic ties may cause the hose to collapse and restrict oil flow.
8. Fill the selected Full-flow and By-pass filters with the same motor oil being used in the vehicle. Lubricate
the filter gaskets with oil and spin filters onto mount. Tighten per instructions on the filter can.
E. Start up procedures
1. Check that all fittings and hoses are securely attached, and that the hoses are routed properly.
2. Check engine oil level. Fill to full mark if necessary.
3. With the equipment secured start the engine and immediately check oil pressure.
Note:
Pressure
may initially take a moment or two to rise. Installing the Dual Remote By-Pass System may
result in a slight vibration sound in some applications. No harm to the engine will occur. Please
contact AMSOIL Technical Services for more information.
Caution:
Carefully check for leaks at fittings, hoses and mount. If leaks are observed,
STOP
ENGINE IMMEDIATELY,
repair leaks and continue.
4. After engine has warmed, shut off and re-check engine oil level. Top off as necessary.
5. Record equipment/operating hours and date of installation.
F. Periodic maintenance
1. Periodic visual inspection of the fittings and hoses is recommended. Check for leaks, hose
deterioration and cuts. Repair and/or replace as necessary.
2. Refer to Recommended Filter Change Interval chart for servicing intervals.
3. To change the filter elements:
a. Ensure engine is off and use caution as the engine, oil and filter may be hot and could result
in an injury.
b. Using a filter wrench, remove the filter elements. Dispose of properly.
c. Clean the filter gasket contact areas on the mount with a clean, lint-free rag.
d. Lubricate the new filter gaskets with clean oil or grease.
e. Fill filters as full as possible with engine oil.
f. Screw on new filters, tighten per instructions on the filter can.
g. Start engine and check for leaks.
h. Check engine oil level, fill as needed.
4. Record equipment/operating hours for future reference.
