ENGINE COOLING SYSTEM
Engine cooling system overhauling
Verifying too high temperatures of cooling uid, check the radiant mass. Whether
on ns are noticed obstructions to the air ux as leaves, bugs, mud etc., carry
out removal of these obstructions taking care not to damage radiator. If distor-
tions 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.
