Water Pump and More ?'s

[CCA-F450]

So I started my project today and after taking everything apart I just had a few questions before starting to put it all back together.

Water Pump ?s
1. I meant to flush the water system before I removed the water pump but got a little ahead of myself. Now I'm wondering if theres a way I can flush out the block with a garden hose thru the hole in the block and out the drain holes on the bottom? I would prefer to do this before installing the new pump and filtration system then flush with distilled water after it's back together...thoughts?

2. The new pump I got has a 90* elbow on it vs straight out on the old one. Is this a common mistake and or a big problem when going to install? I'm hoping the lower hose that I got will match up to it or at least enough to wear I can cut the hose down to fit...

3. Anybody have any issues installing the DieselSite.com Coolant Filtration system while using the dual alt upper rad hose? I vaguely remember reading something about the filter and hose rubbing together. I would really like to use the hose that routes around instead of thru the serp belt if at all possible!

Power Steering ?s
4. Any recommendations on ATF to refill when it's back together?

5. Is there a special procedure I should follow when refilling everything? I am replacing the pump, pressure lines and return lines.

6. Just in general, do you guys have any suggestions where I should use different thread compounds? (ie. anti seize or thread locker)

I'm gonna post some pics in a minute of what I got done today too, so watch out for those...

I think the difference is the single alternator version is the 90* bend, and the dual is straight.

Mine rub, Not a terrible amount, but I still run it. Might should get a hose sleeve for the upper.

You drained that? I'd flush with some synthetic ATF

5. Is there a special procedure I should follow when refilling everything? I am replacing the pump, pressure lines and return lines.

Nothing special. For flushing, I'd do multiple distilled water fills, runs of the motor/pump up to temp, drains, repeat to get all the tap water out. Then fill with 4gallons of your antifreeze. A CAT EC-1 rated ELC is a good idea. Then top off with distilled water. That will get you a 50/50 mix.

6. Just in general, do you guys have any suggestions where I should use different thread compounds? (ie. anti seize or thread locker)

I didn't and I've had it apart since I replaced it the first time. I'd suggest the Dieselsite billet thermostat housing.

jesilvas, sorry, I should've clarified, I'm doing a bunch of work to the truck in a sort of "while-im-at-it" mentality (water pump/hoses/therm, PS pump and lines, Adrenaline HPOP, Aux Fuel Pump, Fuel Bowl rebuild, the list goes on and on (heres a link to the thread I started with a parts list Doing Some Work, Any Suggestions?)..

2. that's weird because the truck only has 1 alternator? I'm actually wondering if the water pump has been "serviced" before cause it honestly looks like someone was beating on the clutch fan nut with a hammer and there is rtv gunked on the pump and the outlet

my ? #5 was actually directed towards the Power Steering system and a procedure to fill that since I am replacing the pump and pressure/return lines..

any thoughts on pumpin a garden hose thru the block and out the drain plugs with a garden hose? I don't see it being an issue, but this is my first diesel project so there's a lot I don't know lol

I already got the billet housing and 203* therm from them

[jesilvas]

Ok gotcha.
For powersteering, I'm not sure. I think just get the front tires off the ground and fill the reservoir, crank so it runs the pump, and keep refilling as you pump the brakes and turn the tires.
The garden hose idea sounds fine, I just don't know how much you can actually push water through the block.
Heater core, use a flush kit to do that.

She's officially in the "OR". It rained all day today so I wanted to keep dry (from the rain that is, it's impossible to avoid coolant and oil around this truck, you'll see why in a sec)


This is one thing that prompted this work. This truck leaks like a siv and we can't have it leaking all over our clients driveways! So i figured if I'm gonna replace the water pump I might as well take everything off the front of the motor to look for leaks and so it began! It's looking to me like most of it might be coming from around the front of the oil pan though unfortunately. What do yall think?





Here's the water pump right before I took it off, see the straight outlet?

Do y'all think it would be ok if I rigged something up to pump the garden hose thru the heater core hose that connected to the water pump too? Does the heater plumb back into the block?

typically when you buy a new waterpump it comes with both the straight and 90 elbow, the 90 is for the vans, its weird yours didnt come with both

[CCA-F450]

Well, ran into my first big issue. The drivers side water drain plug rounded out but I got the passenger side out..question is how good of a flush can I get without removing the driver side plug?

Just replaced my water pump too mine only came with a 90 and the old one was straight couldn't never find a hose so I cleaned my old one and reused and if your using billet therm housing better get some rtv and put around the oring I could never get mine to seal and get antiseeze to put on the 3 bolts holding therm housing

+12 on the RTV sealant.
All my connections leaked the first time. Clean it all good, and still use sealant.
I'd run the water hose until it comes out clear with it on, then put it all back together after draining what you can and refill with distilled water. Run it for a while. Drain. Distilled. Run. Drain. I went through about 3 cycles of that and felt good enough I got enough tap water out. Then drained and refilled with half coolant/top off with distilled water.
