In this project, we will not only be replacing the radiator, but we will
also be replacing the water pump with a nice (slightly used) polished
aluminum offering from Weiand. We will also be disconnecting the
heater hoses and getting those out of the way. First thing's first...
lets get rid of that nasty old water pump. Some of these steps will
overlap with the camshaft swap, so be patient until I get that section
up.

|
Icky old water pump... behind the
pulley of course
|
Ahh... now there we go. I
hate scraping gaskets.
|
I also pulled the heater hoses (after blowing out the remaining coolant)
and plugged the firewall holes. I had a set of body plugs laying
around that I was forced to buy just to get one plug, and I found a pair
of plugs in there the PERFECT size.
|
|
Plugged holes. No more unnecessary heat
in the passenger compartment
|
I also have to mount my temp sensor someplace. I was going to mount
it in the water pump, but I was advised against that. I found an
alternative. I am going to install it in the STOCK temp sender location,
and then move the stock sender (for the gauge) to the water pump. It
beats trying to hack up my radiator, and it can be changed if it doesnt
work.

Stock pump.. see the passage there?
Coolant flows through there, and would spill out of that hole
you see the vacuum tree in if the tree wasnt there.
|
One problem though... that passage doesnt exist on my aluminum water
pump that I am going to use. Hence, I will need to drill a passage
to let the coolant circulate:
|
|
 |
|
Uh oh... no hole... what in the
world will I do? DRILL IT BABY!!
|
There we are! Nice little hole.
Water will flow OUT of this hole and into the block.
|
So now that the hole is drilled, I need to install the sensor. Unfortunately,
the hole in the pump is 1/2 NPT, and the sensor is 3/8 NPT. I considered
duct taping it shut, but I fought back my Kentucky roots and decided to
get a bushing
|
|
 |
|
Sender with the bushing... both
with their teflon.
|
Ahh... perfect placement of the
hole! See the sensor? It's a beautiful thing!
|
And finally...
|
|
|
Worked out VERY nice. I get
to use the stock hole for my fan sensor, and still retain gauge
functionality
|
And the water pump is COMPLETE.
