maintenance schedule. If the vehicle is 
being driven in severe conditions, more 
frequent oil and filter changes are 
required.

cracks, excessive wear or oil saturation 
and replace if necessary.
Drive belts should be checked 
periodically for proper tension and 
adjusted as necessary.
 
When you are inspecting the belt, turn the 
engine off.

abrasions, and excessive swelling 
indicate deterioration. Particular 
attention should be paid to examine 
those hose surfaces nearest to high heat 
sources, such as the exhaust manifold.
Inspect the hose routing to ensure that 
the hoses do not come in contact with any 
heat source, sharp edges or moving 
component which might cause heat 
damage or mechanical wear. Inspect all 
hose connections, such as clamps and 
couplings, to make sure they are secure, 
and that no leaks are present. Hoses 
should be replaced immediately if there is 
any evidence of deterioration or damage.
