Maintaining and replacing coolant hoses

Inspect the coolant hoses every year for cracks and leaks. Replace any coolant hoses that
have cracks or leaks. If the hose couplings leak, then replace the EPDM seal/gasket.
Coolant
Coolant can escape when the coolant hoses are disconnected. The coolant is harmful to eyes
and skin and can damage surfaces.
Therefore, wear appropriate protective clothing for all work on the converter. However, if your
eyes or skin do come into contact with coolant, rinse the affected area thoroughly with tap
water as soon as possible. If coolant leaks, eliminate the source of the problem and remove
the liquid from the surfaces affected.
Replacing coolant hoses
Before you start to replace the coolant hoses carefully ensure that there is no coolant in the
hoses.
