Pump Installation Instructions
Before installing your new Flowkooler water pump:
1) Do NOT PAINT YoUR PUMP BEFORE CHECKING IT IS CORRECT FOR YOUR APPLICATION. We cannot accept returns due to fit if they are unsaleable as new pumps.
2) Disconnect battery.
3) Drain coolant. Thoroughly flush and drain the
cooling system.
4) Check hoses, clamps, radiator. Examine the
hoses, clamps, and the radiator and cap. Repair or replace
if necessary.
5) Gain working room. If necessary for working
room, remove the radiator, fan shroud, and other components.
A few minutes spent analyzing adjacent components and
removing those in the way may save you hours of lost labor.
6) Remove belts. Remove all belts that ride on the
fan pulley.
7) Remove the fan. Remove the fan and inspect it
carefully. Important: A flying fan blade can be deadly! If
you detect any evidence of cracks or bends in a fan, replace
it. Never try to straighten or repair a fan.
8) Inspect fan clutch. If a fan clutch is present,
check it for evidence of fluid leakage. If the fan spins
more than five revolutions when turned by hand, the fan
clutch mechanism should be replaced. Faulty fan clutches are
a major cause of overheating (See
Fan Clutch Overview).
How to install your new Flowkooler water pump:
1)
Flush cooling system if it shows signs of corrosion.
Clean pump impeller cavity and gasket surface. Tighten back
plate mounting bolts where applicable.
2) Position new gaskets after coating them on both
sides with sealer. Check rivet head clearance with open
back impeller chamber type pumps before coating gaskets (see
instructions in box).
3) Carefully install new pump. Do not strike
shaft! Tighten pump bolts hand-tight, then torque them in a
criss-cross pattern to manufacturer's specifications. Note:
On some applications, it is necessary to apply a sealant to
the mounting bolt threads. If there are traces of old
sealant on bolts, or evidence of corrosion of the bolts
(from contact with coolant), clean threads and apply
sealant.
4) Turn pump shaft by hand. It should move freely.
5) Check thermostat and radiator cap. Replace if
they show signs of sticking or leaking.
6) Connect hoses and fill cooling system. Check
for leaks. Fill system according to manufacturer's
procedures.
7) Check fan blade for cracks, bent blades, loose
rivets, etc. Never straighten a bent blade! If any
defects are found, replace the entire fan.
8) Check fan clutch (if used) for loss of oil,
looseness, or wobble. A bad or misaligned clutch will
damage pump. (See Fan Clutch Overview)
9) Check that the fan pulley (or clutch, if used) sits
square on the pump hub. Using lock washers, torque bolts
evenly to assure wobble-free operation.
10) Rotate fan by hand and check for fan wobble:
3/32" maximum at outer edge (with no fanclutch); 1/4"
maximum with fan clutch.
11) Check belts for cracks, frayed edges, missing
sections. If in doubt, replace belt(s).
12) Adjust fan belt(s) to proper tension, using
commercial tension gauge, if available. Or lay straight
edge between alternator and pump pulley and adjust belt
deflection to1/2"to 3/4". (See vehicle manufacturer's
specifications for recommended tension.)
13) Check fan clearances at blade tip, between fan and
shroud, and fan and radiator.
14) Check motor mounts for wear or splitting.
Check bolt tightness, cracked or damaged rubber in mounts. A
broken motor mount will let the engine "rise up" under load,
causing the fan blades to contact the shroud, hoses, etc.;
this results in damage to all, including the water pump.
15) Start engine andrun until normal operating
temperature is reached. Check for leaks and for smooth
operation. Never stand in line with or near fan when revving
engine! For your own protection, the hood should be closed
when revving engine.
Note: Many things can cause water pump failure,
including defective, crooked, or unbalanced fans; defective
or unbalanced fan clutches; excessive (too tight) fan belt
tension; dirty cooling systems; insufficient clearance
between fan and shroud or radiator; loose or broken motor
mounts. Check everything when you have the chance; help
avoid future water pump failures. This product intended only
for use as originally specified by the OEM manufacturer
and/or the catalog.
Caution: The addition of more water than
recommended will raise the freezing protection temperature
and weaken the corrosion inhibitors. Refer to specifications
for the cooling system capacity for all vehicles.
Note: The system must be maintained with the
correct concentration and type of antifreeze to prevent
corrosion damage. The coolant normally contains a 50/50 mix
of water and permanent coolant. |
