[DML] Re: Coolant Leak Problem HELP ME!

["cruznmd" <racuti1@xxxxxxxxxxxx>]

How old are your hoses? 

As "someone" suggested, it's either a hose on the rear of the pump or 
the waterpump shaft seal has blown. There is a hole in the casting on 
the underside of the water pump shaft where the coolant runs right 
out if the seal is shot. You can stick your finger behind the pulley, 
on the underside of the casting and feel it.

I hate to break it to you, but you usually have to remove the intake 
for this job. I was able to do it without pulling the intake once but 
only because I had screwdrivers of all funky lengths and all the hose 
clamp screws were pointed in -exactly- the right directions. In the 
end, I had to pull the intake to seat everything properly anyway.

Contrary to popular myth, this is -not- an impossible job. I'd say 
removing the fuel/mixture control unit is the biggest hassle, not the 
intake. The only trick is merely to lable all of your hardware, fuel 
and electrical connections for easy reassembly. Oh, and buy the 
intake O-ring seals from a vendor -before- you begin. This will 
prevent vacuum leaks at reassembly.

As David Titlebaum's favorite phrase is "While you're in there..."
I recommend replacing all hoses in that vicinity. That way you only 
have to go in there ONE time. Heck, I was so paranoid I even replaced 
all switches and sensors in the coolant "Y" pipe under the intake 
with brandy-new ones from Houston. Also inspect that metal heater 
hose pipe to make sure it's not about to rust through. It also runs 
under the intake. Lastly, clean out the castings in the "valley". 
Make sure there's no coolant rotting a hole in the engine block on 
you, and get all the dirt, hardware, dead rodents and what-all that 
have accumulated in there.

Despite the length of my reply, it's not that ugly of a job. A day, 
depending on how rusty your engine hardware is. Many days if you snap 
off a bunch of bolts. :)
