Removal and fitting
Caution
If Brembo brake callipers are being used take care that they are not scratched by other
components or tools because there is a chance that the paint might peel off. In
addition, if any brake fluid gets on the callipers, it should be wiped off immediately.
Jobs to be completed before removal and after fitting
•Removal and refitting of the valence. (Ref Section 51: Front bumper)
•Removal and refitting of the LH side cover.
•Checking and adjustment of the tension of the drive belt.
•Removal and refitting of the crankshaft pulley.
•Removal and refitting of the cross member bar.
•Removal and refitting of the front exhaust pipe.

General
The following servicing guidelines for the water pump and the water hose and pipe have been prepared for vehicles which use
the 4G63-MIVEC-T/C engine. Other servicing guidelines remain unchanged.

ENGINE COOLING – WATER PUMP14-2
Water pump
Removal and fitting
Jobs to be completed before removal and after fitting
•Draining and refilling of the coolant
•Removal and refitting of the timing belt (Ref Section 11)
Removal procedure
1. Alternator bracket
2. Water pump
3. Water pump gasket
4. O-ring
Fitting guidelines



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

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.
