water pump / thermostat replacement

***elephantrider*** · 04-08-2009, 10:43 PM

quick how to on replacing the
thermostat and water pump.

remove thermostat housing via
7mm bolt ( 3 )

remove old thermostat

clean off facing and apply gasket sealant, and
replace with new thermostat

next remove the water pump via 10mm
bolts ( 2 ) - note that it really helps with
access if you remove the airbox if you still
have the oem box

try and dry as much antifreeze from the both
facings as well as remove any old gasket
material

here is the oem and the replacement - odd thing
i noticed was the the oem pump did not have
a seep hole, but the replacement did.

apply gasket sealant to the underside of the
rubber o ring then seat the ring in place. once
that is done apply additional sealant to the top
of the o ring and around the bolt holes just to
be safe, once again ensuring that no sealant
gets on the water pump fins

reinstall the water pump with the oem bolts and
reroute the serpentine belt and wah lah your
done.

hope this helps some peeps

Good write up

It will probably help a few people on hear. It seems so basic, but usually the easy things are the ones people are afraid to ask about, fearing the will look dumb.
