Removal guidelines
 
A


Removing the radiator upper hose and the radiator
lower hose
Mark the radiator hose and the hose clamp with indicator marks
and then remove the radiator hose.
Fitting guidelines



A 
Fitting the O-ring and the water inlet pipe
Fit the O-ring into the groove at the end of the water inlet pipe, and
insert it after moistening with water the places where the O-ring and
the water inlet pipe will be in contact.
Caution
Ensure that absolutely no engine oil, or other type of grease,
gets onto the O-ring.



B 
Connecting the radiator lower hose and the radiator
upper hose
1. Insert the hose as far as the protrusion on the water inlet pipe
and the water outlet fitting.
2. Match up the indicator marks on the radiator hose and the hose
clamp, and fit the radiator hose.
