Even the S-10's aren't that hard. I have an 88 S-10 4.3 and did it 8 weeks
ago on the side of the road with a hot motor in the dark. Brutal, yes, but
only because I had worked all day and my back was shot, and I was hustling
to get it apart before the sun set. Long story short I didn't get it done
before it got dark, which really makes it a lot harder. All told, I spent 2
hours doing it. I knew it was dieing, so I had the new pump and
anti-freeze. It blew on the way home from the parts store. This was the
most catestrophic failure of a pump I have seen. We're talking bearings
sheared in half. I got the truck pulled to the side of the road and shut
off just in the nick of time. I think had I waited a few seconds more I
might have had fan hitting the hood or worse. Sometimes you just listen to
that little voice...
Take a half inch drive and socket and take tension off of the serpentine.
This is a good time to replace the belt. Draw a diagram of how it wraps
around everything. Really, draw it, you'll be cussing if you don't. Take
off top half of radiator shroud. Usually a few screws and a couple of bolts
on each side. Place shroud on ground. Open radiator cap, and drain
anti-freeze. Loosen and remove bolts holding fan on. These are a PITA, but
doing this keeps you from banging the radiator with the fan on removal.
Loosten and remove bolts holding pump, and lift old pump out. Now do
yourself a favor and do a really good job of cleaning the block where the
old gasket was. Make sure you get any little drops of anti-freeze out of
the passage ways in the block, as if this runs out while you are putting the
new pump on, you might not get the new gasket to seal. I use copper coat
spray on the gaskets and put the bolts through the new pump/gaskets and put
it back onto the block. Re-assemble and you should have many years of cool
running.
Additionally, on my truck you have to remove all the air cleaner system, as
it gets in the way, but I don't think any of the 95's have the TBI setup
like mine to get that in the way.
While you are in there, replace the serpentine belt, the upper and lower
hoses, and put a new thermostat in as well and save yourself a headache down
the road.
No real special tools, but having a half inch drive set to take the tension
off the tensioner pully is the only way to go. I've done it once with brute
force, and once with the half inch bar and socket, and believe me, it's
worth the few dollars to buy the tools. That or have a second person,
because trying to keep the belt on the pullies and cranking on the tensioner
is quite challenging by yourself without the right tools!
