Make sure the engine has cooled off before begining!
Buy a tube of RTV sealant, Permatex brand is recommended.
Option: Buy new hose clamps when you buy the water pump!
Option: Buy new hoses.
1. Disconnect the Negative side of the Battery (precautionary
measure only).
2. Drain the cooling system.
a. Mfg. says to reuse if it has
recently been changed, but spend the $6.00 for new Anti-Freeze.
3. Loosen the clamps and detach the hoses from the
water pump. If they are stuck, grasp each one with a pair
of adjustable pliers and twist
to break the seal, then pull off. If the hoses are deteriorated,
cut them off and get
new ones.
4. Remove the cooling fan shroud, Fan & viscous
clutch assy.
5. Remove the drive belt(s), and pully from the end
of the pump shaft.
6. Remove all accessory brackets from the water pump.
a. If removing power steering
and A/C compressor, do not disconnect any hoses, tie units aside with them
attached.
7. Remove the timing belt and idler assembly.
8. Remove the bolts, and detach the water pump from
the engine.
a. Note the different lengths
of the bolts, and where they went.
9. Clean the threads, and threaded holes on the bolts,
and engine to remove debris, and/or corrosion.
10. Compare the new pump to the old one to be sure you have the
right model.
11. Remove all traces of old gasket material with a agsket scraper,
or straight razor.
12. Clean the engine and new pump mounting surfaces with laquer
thinner or acetone.
a. Install new rubber seals in
the ridge gaps at the top and bottom of the pump.
13. Apply a thin coat of RTV (Permatex) sealant to the engine
side of the new gasket.
14. Apply a thin voat of RTV sealant to the gasket mating surface
of the new pump.
a. Carefully mate the gasket to
the pump; slip a couple of bolts through the holes to hold in place.
15. Carefully attach the pump and gasket to the engine, and thread
the bolts into the holes, finger tight.
16. Install the remaining bolts (with any accessory brackets).
Tighten them to specified torque in 1/4 turn
increments. Do not overtighten
them or the pump may be distorted.
17. Reinstall all parts removed for access to water pump..
a. Timing belt & Idler assy.
b. Pump pully
1. Fan
Clutch & Fan
c. Drive belt(s)
d. Fan shroud
e. Hoses
1. Use
new clamps if you can, and use the kind you tighten with a nut, or screw
driver.
f. Refill cooling system (after
you have, or have not decided to let it sit for a while to cure)
g. Reconnect (-) Side of battery
Lastly? Do you have any parts left over? Hope not!
Is is best to let sit for a few hours, the RTV instructions say it needs at least eight or more hours to cure!
My uncle once used RTV as a Carburator gasket. He did not let
it sit long enough to dry. When he started the engine, it ran fine
untill he saw gasoline spraying out of the carburator. Why?
The carburator sucked the RTV into the unit, and clogged up just about
everything. So, it's a good idea to let it all sit for a while, even
before refilling with coolant.
