protection. Dex-Cool
®
meets ASTM D 3306 standards and is
recommended for use in automotive applications.
The PSI 8.8L LPG engine requires the use of a 50/50 mixture
of Dex-Cool
®
and water. This mixture will not vary depending
on ambient temperature, the mixture will always remain 50%
Dex-Cool
®
and 50% water.
Contamination of Coolant
Coolant color can help indicate the condition of the coolant.
•
Coolant color should be orange (clear - not cloudy).
•
Coolant must not have floating debris or visible oil.
•
Over time, Dex-Cool
®
may begin to change to a pink color.
This is normal and should not be a concern as long as it
remains clear and free of debris.
For coolant part numbers, capacities, and other antifreeze
information, refer to the Engine Operation and Maintenance
Manual.
Fan Clutch
Inspect for proper operation, secure electrical connections, or
air supply as appropriate. See the applicable Service Manual
for details.
Heater and Coolant Hose Inspection and Replacement
Guide
Proper maintenance and inspection of the heater and coolant
distribution system is required to maximize hose life, maintain
performance of the system, and avoid potential failures.
Poorly maintained coolant is cause for hose failure. Coolant level
and condition should be inspected on a regular basis.
•
Check coolant level as part of the daily inspection.
•
Check coolant concentration per coolant manufacturer
requirements.
Heater and coolant hose inspections should be performed on
an annual basis, or anytime a hose repair is made. To properly
inspect engine and body heater hoses, protective metal or
plastic covers and closeout panels are to be removed to allow
inspection of the complete heater and coolant / hose system.
Once protective covers and closeout panels are removed, the
following basic steps should be followed.
•
Perform a visual and touch inspection of all hoses. Hose
inspection process is to include all engine compartment and
body, interior and under body, hoses.
•
Check heater and coolant system for signs of cold and hot
leaks.
•
Pay attention to the hose ends and contact points that will
typically show early signs of hose failure. Observe the area
around all hoses for signs of leakage.
•
Synthetic rubber can oxidize and harden over time.
Squeeze the hose to make sure it is pliable. Entire hose
length should have a consistent feel and appearance.
