Inspecting Coolant Level and Hoses
Proceed as follows to inspect the coolant level and
hoses:
1. See Figure 5-6. Verify coolant level is between
HOT and COLD marks on the overflow reservoir.
Figure 5-6. Coolant Overflow Reservoir
NOTE: Coolant expands when hot, so coolant level may
be higher than the HOT mark. Do not add coolant higher
than the HOT mark.
2. If coolant level is below the COLD mark, remove fill
cap from overflow reservoir and add coolant. See
Coolant Water Treatment.
3. Inspect coolant hoses for leaks. Tighten hose
clamps, if necessary.
4. Inspect hoses for nicks, cuts, tears, or general
deterioration. Replace as necessary.
