Engine cooling system overhaul
If the coolant runs too hot, check the radiators. Any foreign matter trapped
between the ns (such as leaves, bugs, mud, etc.) will obstruct air ow and
must be removed carefully to avoid damage to radiator. Straighten any bent
ns to ensure free ow of air. If the cooling mass is clogged or damaged, no
more than 20% of its surface must be affected. If damage exceeds this limit,
the radiator must be replaced. Periodically check the connecting hoses (see
Section B, “Scheduled Maintenance Chart”); this will avoid coolant leakage and
consequent engine seizure. If hoses show cracks, swelling or hardening due
to sheaths desiccation, their replacement shall be advisable. Check the correct
tightening of the clamps.
