Engine cooling system overhauling
Verifying too high temperatures of cooling fluid, check the radiant mass. Whether
on fins are noticed obstructions to the air flux as leaves, bugs, mud etc., carry out
removal of these obstructions taking care not to damage radiator. If distortions are
noticed, it is advisable to straighten them so restoring the air passage. The radiant
mass has not to be clogged or damaged for more than 20% of its surface. If the
damaged surface is over this limit, it shall be advisable to replace radiator.
Periodically check the connecting hoses (see "Periodical maintenance card"
page B.8): this will avoid coolant leakages and consequent engine seizure. If
hoses show cracks, swelling or hardenings due to sheats desiccation, their
replacement shall be advisable. Check the correct tightening of the clamps.
