On hot sunny
day this summer Cam (BlancoBronco), Emmet (ILVTNA, MudMad) and
I went for a little 4x4 adventure but it was cut short when
The Beater was charging up a hill and the radiator decided to
blow chunks. It had overheated on 100 + degree days before but
nothing like this.

I wanted to
not only fix the problem but take it up a notch so this won't
happen again. Emmet hooked me up with a heavy duty radiator.
It's twice as thick as the stock one so it's a good start. I
have seen a few write-ups from people that ditch the clutch
fan and go totally electric. I like the idea but I want total
I headed to
the local Pick-a-Part and spent a few hours digging up a
couple Ford Taurus 3.8 Liter radiator cooling fans. These draw
a lot of power so I also grabbed a high output 130 amp 3G
alternator from a 95 Mustang. My brother came by later to help
me with this project.
I had to
shorten the fan shrouds about 3/4" and carefully cut out
areas for the hoses and transmission cooling lines. Each one
has four nut and bolts holding it down firm. I also had to
fabricate some custom brackets since the fan on the far side
sticks out a little past the radiator.
Here is how
the brackets look under the shrouds.
installed the first 3G alternator. I used 4 gauge switch to
starter cables since this is a 130 amp alternator.
We placed a
175 Amp Mega Fuse with a bling bling fuse holder from the
audio section since no-one had a normal one in stock.
since I had everything out I would go ahead and replace the
water pump. Bad Idea! I ended up braking off two of the bolts
that go all the way through to the block. We spent the rest of
the day trying everything easy outs to welding nuts onto the
stubs to try and remove them with no success. We decided to
try and use the 5 remaining bolts and a heavy amount of
silicone to keep it from leaking. We got everything but the
fans wired and started it up.
installing the new water pump, it didn't leak there but did
leak between the timing chain cover and the block. I
also got nothing from the alternator so I took it to Pepboys
where it failed all tests.
So we removed
the radiator, all the pumps and hoses and spent hours trying
to fineness the timing cover off with no luck. Those two
snapped bolts were holding it tight. I finally decided to get
tough and using a dremel with a cutoff wheel and a grinder
with a cutoff wheel I cut out about half the bolt leaving
enough of the housing to be able to eventually get a new nut
on there to hold it tight.
what appears to be a core sample you can see why the cover
didn't want to budge. 15 years of rust had welded the things
in place. there isn't even threads there. Of course once we got
the timing cover off what remained of the bolts unscrewed with
With only 1
1/4" left we were able to pry the timing chain cover off.
(#$@% Penzoil!) It looks like it's time to change the timing
chain since I have it broken down this far. while relieved we
finally got to a point where we can start putting it back
together this is way further than I planned on taking it.
weekend I went back to Pick-a-part and got another 3G from a
1988 Taurus and a couple water pump bolts off an older 351. My
brother came back for another weekend of torture and we
started by placing the new timing chain set in. It's not only
cleaner but the new chain made it a nice tight fit. We spent
the next few hours muscling the timing cover back on. It was
getting dark so we will continue putting the Beater back
together in the morning.
start but we got the water pump back on then all the pulleys,
serpentine belt and hoses connected.
Before we put
the radiator back in I decided it wasn't Beater enough. It
needs a hole in the fender.
With the size
of the new radiator and fans I couldn't replace the fresh air
intake so I flipped the filter box and made a new one.
in my head are spinning on ideas for a scoop or snorkel or
some other way of pumping air into the box. Sometime I will
get a K&N or similar filter.
By the time
it got dark we had the radiator back in and all the hoses and
stuff back in. Tomorrow we will fill the fluids, change the
oil and oil filter then wire up the fans.
It was 100
degrees outside on Sunday so not a lot got done. We changed
the oil and filter added water and started her up. It seems to
be doing OK so far. The 3G from the Taurus works and there are
no leaks. I have the fans wired to the relay. I will
need a second one for high speed. I'll do that next week. Here's my
solution for the cold air intake, for now anyway.
I got a
second relay and made a bracket to hold them in place.
now I wired the low speeds only. One is switched to the AC
condenser. It will run with the AC on. The other is connected
to the Fan controller from my old wimpy fan. It is set to 180
degrees. I also ran the high speed wires from the fans to the
relays so I can easily switch it out if necessary.
drove it about five miles and popped the Mega fuse. I will
have to take a look and see what caused that to happen. It
worked fine at idol (14.3 Volts) but when I gunned the motor
it blew the Mega Fuse. I ordered a 200 Amp circuit breaker
from a car audio place to replace it.
installed the circuit breaker and managed to break it within a
few minutes of installing it. The web page states that you
push in the button to reset it. I did that since it was
sticking out and went to move the arm where it says 200A. I
broke a small piece of plastic on the inside. When I took it
apart it could see that pushing it in actually breaks contact.
I am waiting for the JB Weld to dry on the small broken
is the fan controller from the old aftermarket fan. The guy
that installed it didn't have it wired properly. The yellow
goes to positive, black to negative, orange to the fan and he
had the green going to the AC condenser which does nothing.
There is a small black that goes to a temp sensor in the
radiator. I think if you insert a relay into the socket the
other wires are for the high speed side but I have no idea
where the red and blue go. (red to high speed power and blue
Well the fan
controller ended up being bad so I wired the second fan to a
switch on the dash. I started the Bronco and the serpentine
belt started screeching, then smoking so I shut it off.. The
alternator was burning hot so I thought it seized up. NO that
would be my second one. I pulled the belt off and the alt spun
free so that wasnít the problem. I got a strait edge and
compared it to the other pulleys and it was about ľĒ off. I
went to pull it and the sparks started flying. The 4 gauge
cable from the alt had melted the housing and was shorting
out. I pulled the battery cable then removed it.
After a short trip to the Zone for a new cable I cut the end
off the sleeve that fits in the bottom hole of the alt bracket
so it could move forward. It was a little too much so I used a
thin washer to get it just right. I then used two 1/8Ē thick
washers on the top alt bracket hole to even it out. Now it all
lines up just right. It only squealed once before since I
installed it and it was just for a second at startup. Why it
decided to squeal now I donít know, but itís fixed. I also
noticed my lower radiator hose was a little too close to the
belt so I loosened it and moved it out of the way.
I took it for a drive and now the temperature gauge fluctuates
between the N and A on normal. Before it pretty much stayed in
one place. Other than that it seems to be running really good.
It's a few months later
and one of the fans was making more and more bearing noise. It
was the main one I was using so I decided to just go with one
I got an adjustable fan controller
(180 to 220 degrees) and wired it with two switches. One
with auto off manual and the other with high low. it goes
thru the first switch, auto for the controller or manual for
a hot lead or off to override it when forging deep water.
then it goes thru a high or low fan speed switch. from there
it goes to the two relays one for each speed.
