replacing the water pump on a 95 ram 2500 5.9 and wnt to install the brass fitting from the old water pump for the hose that comes in from the drivers side and ther are no threads for it. Is this normal? any suggestions would be thanks .

 

that is normal. look in your water pump box/bag to find o-ring that goes on that pipe. remove old pipe from old water pump and replace old o-ring with new o-ring. oil or grease it. wait until you have new water pump bolted on and then push the pipe down in the pump. use the mounting bracket on the pipe to know when its seated all the way in. you have to push it pretty far (and hard) down into the pump. amazingly it doesn't leak.

 

I had the O-ring in my pump and didn't think about it. I sealed mine with RTV. Now that I think about it, maybe that's why I keep losing coolant[:@] Thanks, now I have to check that out!

 

thanks, so i swapped the fan over to the new water pump that does not have the 4 bolts that hold the pulley on, the pulley is permanently fixed to the water pump with a couple of spot welds, eliminating the leverage i used to remove the fan from the assembly (excessive force required) if i would need to take the fan off again would i be SOL?

 

on both the old water pump i took off, and the new water pump i put on, the pulley was on the shaft with no bolts, so there was nothing to grab ahold of. there were 4 holes in the pulley and i bent a couple of short screwdrivers trying to hold the pulley against the wp through those holes. i was thinking about making some kind of sturdy tool to insert into 2 of the the holes, but i just went ahead and unbolted the wp from the front of the engine and lifted out the wp, fan, and shroud all in one piece. once off, i put the wp in the vise to get the fan off. another stupid design in my opinion.

 

here's an archived post that may have info of value:

" I have researched the heater fitting issue and have found a replacement for
the press in tube with the o-ring. I work at a NAPA and mentioned this in
another thread a couple days ago, but I wanted to get good solid research in.

The water pumps on a early Magnum (92-93) have a threaded heater fitting and
are the same both in height of pulley and mounting pattern. They are also the
correct rotation on the impeller.

Here are some part numbers, whether you have a press on or bolt on pulley:

NAPA part#
58-447- bolt on pulley, threaded heater fitting

58-559-pressed on pulley, threaded heater fitting

I looked both of these pumps up for a 92-93 Dakota with a 318.
Both are rebuilts for about 50-60$.
Just thought I would satisfy some curiousity.

{HankL's note: the 1993-2001 5.2/5.9 Magnum V8s have on the driver's side a
5/8ths slip in fitting with an O-ring that is VERY prone to leaking when
changed. The threaded fitting water pumps above should be considered for less
hassle}

 

I am betting that's what is wrong with my truck. I have bled the air out of that thing continuously, topped the coolant level, yet it keeps losing coolant! [:@] I am going to check the water pump this week when the rain lets up.

 

the brass fitting has standard thread, used in the plumbing industry, so i tapped the water pump with a 1/2 inch tap, used a little teflon tape and still used the oring and thats it , now if i can just figure out where this extra bolt goes....
