LT-1 primary fan removal/replacement.
(The manual is REAL wrong on this)
And to save anyone any added trouble, here's my recommended tool set for
1/2" box wrench, long (fan to motor)
1/2" socket 1/4" drive. (fan to motor) long handle
10mm open end, short (motor to bracket)
10mm socket (bracket to shroud, shroud to radiator cover)
12" pry bar
This was so much more than the manual said. I had to remove the bracket
screws, of course. Then remove upper radiator hose. Here's the rest- loosen
the three schools that hold te motor to the bracket. REmove the screws that
hold the a/c accumulator to teh shroud, and the remainder of the shroud
upper screws. Now, after backing teh motor mounting screws (3 of 'em) out
about 3/16", pry the power connector off the motor, and then pull the shroud
top back, it will move about 1" or a bit more. Snake in a 1/2" socket wrench
onto the nut that holds the fan blade assembly on. BAck it off. And then
work the fan blade off the motor, and then carefully back out the three
motor mounting screws. Carefully remove the fan mount bracket, and the
motor, eventually get the fan blade out.
Here's the rest of the story re: installation:
First, out of the car assemble everything to make sure it all fits. The
Siemens motor I bought needed a washer, not much of one, under the nut that
holds the fan blade assembly to the motor.
Remove the fan, place it inside the shroud ahead of putting the
motor/bracket in. next, put the three screws in that hold the motor to the
bracket, but only enough thread in to not let them fall out.
Put the bracket/motor in place, will need to jack around with refrigerant
Once in place (need skinny hands/arms here) tighten the screws that hold the
motor to the bracket. And remember, you have removed the top row of screws
for the shroud.
Pull back on the shroud top, and place the fan blade assembly on to the
motor shaft. It is keyed with several plastic "nubbies" inside the hub.
Next, I used a box wrench to set the nut on the shaft. It is reverse
threaded, so be sure you turn the right way, or you'll be there forever
backing it off. I held the nut with the wrench, and simply spun the fan
blades to tighten, the last bit just had to do that tightening manual type.
At this point, just re-mount all the crap you removed in the process. Don't
forget the electrical connector.
I hope I saved someone some time. I spent way too much time trying to figure
how the manual's method could be accomplished. It can't. Period.
I hope my secondary one hangs in. I really hate moving a/c components.
System is tight, moving stuff can only disturb that status.
