Hi, new to the 4x4 group.
My Blazer is bone-stock.
I would like to find some info on waterproofing my truck, basically just for
fun I guess.
I've found some useful and extensive sources on the web for water proofing
everything but my truck. Most of what I have found would work for my truck,
but if I could get some input on weird things to water proof on my truck,
maybe tips&tricks that people have had luck with it? I would just like to
know that I didn't miss anything.....
Sorry, I forgot the entire run down. I'm usually pretty good about this.

My previous post (that 0 people responded too) had all that info in the
subject. I forgot to put that stuff in when I changed my subject and
reposted (in a desperate attempt for a response...sigh)
Well, since it's full size, I may be able to help....what exactly is
your definition of "waterproofing?". Is it to be able to go fording
through 4 foot water, or just to seal everything nice and tight?
4 foot is kind of mild, that's maybe the hood on a stock k5. But yes,
fording insane depths of water.... keep the engine running while a normal
engine would otherwise be 100% swamped and hydrolocked.
I'm guessing - air pump to keep the diffs with positive pressure, mayhaps
the tranny and t-case too?
Dielectric grease on the spark plugs both ends, how about sealing the
I've read that sometimes fuel pumps have drain holes, breathers of some
It has a clutched fan, should an electric be installed or just let it chew
I've heard of some flexing forward and damaging the radiator....
Any wire harnesses to "Tupperware" into a sealed box?
the usual tubes and stuff like that on all breathers, but are there any
WEIRD (like fuel pump) things that I need to water proof?
I'd also assume that fording is really hard on an engine, and very abnormal
wear. How hard is this on an engine?
Well, your way ahead of me, I can only comment on the fan, yes electric.
with a switch in the cab, so you can turn on the fan on the road to
keep the engine cool and shut it completely off when you ford...
I've been around some forder's before, but havn't really gotten into
myself, the electric fan is a must..never heard of any fuel pump
problems, but that's not to say there isn't one, I don't believe any SBC
has a breather in the fuel pump, just a pressure sensitive hole that is
the first to blow when the pump goes out, but nothing I would think you
would need to worry about fording, I remember seeing an article in a mag
a long time ago (like 3-4 years) on how to water-proff your rig, and it
had a thing on the distributer, don't remember how or even which mag,
mabey search all thier backissue article thingys (some are online, some
you have to call).
If the answer is fording, then here are some suggestions:
Route all axle/trans/transfer vents up nice and high..I ran one hose
down the driver's frame rail, starting at the back for the rear axle,
gradually increased the size of the hose at each intersections (transfer
case, transmission, front axle) and then ran the end hose (ended up at
3/4" id) up to the highest point in the engine compartment.
Wrap your air cleaner with a good large pore (so it shed water and dries
quickly) cloth material, or buy a snorkel kit if your really serious.
The only other thing, that I should really do as well but just havn't
gotten around to is making some nice mud/water dampers to loosely seal
up the engine compartment...seal those front wheel wells to the frame
rail, some front rubber along the bottom of the core support, etc...
