water pump to block contact area

[vsho]

When replacing the H2O pump is it advised to coat the pump to Block surface with non-hardening gasket compound?

When I replaced my water pump I did not use any extra sealing. All you need is that little o-ring to stay in the grove, (which is a pain while trying to fasten it down, they like to fall off so keep looking on the floor,) and torque it to specks. I am not saying that it would not help, it might. Maybe someone else can answer that.

93nighthawk~ I just got a new waterpump and it came with a standard gasget not an o-ring. 94 ATX 3.2L. Just want to make sure of two things I recieved the right part and not tear into it if I dont.

I got my waterpump from O'Riely's Auto parts (I opted for the brand new one, not the rebuild,) It came with 3 O-rings (the Two tubes and one to connect to the block). There was no gasket at all. When I pulled the original one out, all it had were O-rings. I looked at the two, they were identical for parts and sizes (except the old one was a little rusty), so I assumed everything was there. That was a little over two years ago. Sorry I can't be more help.

Well I'm thinking they sold me new front half at autozone. Could you see your impellar.

 

[93nighthawk]

ah, I could see it if I looked at it where it connects to the block, but after thinking about it, are you sure you did not get the re-build kit? It shoul be a whole piece.

Go to www.shotimes.com they have step by step procedure w/ pics. That is where I got started doing my own work, screw paying someone $50+/hr for something you can do yourself.

(below is a pic of the water pump, owned by shotimes.)

Now if it does not look like this, there is something wrong.

It looks like half of that. My new autozone waterpump is only the pump half, simular to what you would get if you bought a reman.

It definitely sounds like you got the rebuild kit. Mine was complete and looked exactly like the pic. How much did you pay for it? I only question how well the new part will mate with your part, if any of it is off, your going to have a leaky water pump. Here is a list off of www.carparts.com water pumps.

I called about the A1Cordone at Oriely which is the same part # you've indicated and it is the same as the one I got just the front (pump) half. Doesn't come with the back housing with the outlet tube.

vsho~sorry I took over your post. Hope you got the info you needed. You shouldn't need any extra sealer. If your in my boat and only purchased the front half of the pump then you will need to use some shalack on the gasket. If your talking about the o-ring apply a little white grease or vasaline on the groove and then put the o-ring in the groove and she will not fall out while you put her together.

It looks like you just bolt it together with the gasket inbetween. I can't believe they didn't sell it pre-assembled. Well the tube the goes down to the lower radiator hose should be able to fasten that on to your new pump. Did you get gaskets for those pieces too? Honestly if I were you I would take it back and get the

(I think that is the one I got, the price sounds about right)

It is a very extensive job tearing into that area of the engine and I would rather spend a little more $$ now on a new replacemnet, than having to spend more $$ and time later.

 

[93nighthawk]

I'm sorry too vsho, You are probably learning more than you every want to know about a waterpump.

 

[vsho]

Purchase a A-1 Cardone for $57 plus some change. The pump is only the front half though. O'well.

Decided to go ahead and attach to the block with the old "O" ring, but I cleaned both surfaces with 600 grit then applied a coat of Permatex non-hardening which I diluted with isopropanol (just insure a uniform thickess.

Now I need two idler pulleys and can not find them in the LA area - no instant gratification have to wait until Wednesday..

This is why I only use the OEM replacement pumps. Comes with water tube O ring, block to pump O ring, and inlet gasket.

Most of the aftermarket pumps are just a front half, and don't even address the rear O rings and inlet gasket, which in my experience leak just as much as the front seal/bearing.

If you use a reman pump from the local store, at least order the Ford O rings and remount the old rear housing with the new rings.

Excellent advice. I would suggest for anyone changing the waterpump to always get a new O-ring for the block seal. Its only a few bucks, but will save a lot of grief. PN E9DZ-8513-B, usually available at a local dealer, or FPN.

When I did my 3.2 swap I replaced the H20 pump with a brand-new unit so I wouldn't have this problem. But It leaks from I believe the o-ring to block. I went through 2 CPS since the swap and after inspecting it in storage the leak still exists (i was hoping it would go away on its own... I know, I know). All teh gaskets, o-rings etc were replaced, I even cleane dthe block where the o-ring mats to it just to be sure but to no avail. I know that RTV is a no-no for coolant leaks, what type of sealer should I use when reinstalling the pump?

 

[SHOtimer]

I have never used any sealant on the block to O-ring seal and it has always sealed. You just have to make sure the block is clean and smooth, and the O-ring is in the groove (and the O-ring is new). I personally wouldn't recommend using any sealant ing the block to O-ring area.

I cleaned the block really well, I sanded it a little to be sure it was smooth then hit i twith brake cleaner. The only other thing I can think of is i did have a littl etrouble getting the o-ring in the groove on the pump, it may have shifted some before I got it flush against the block. well, regardless I guess it has to come off.

 

[Cobraii976]

Well I only buy the front halfs considering I throw away the junk O rings they give you with a full pump. I just hit the hardware store and buy new and thicker for the block. we did a full pump on a customer car and it leaked from the new O Ring fatter ring better seal.

 

[rrg93sho]

you only need the front half the rear housing is a non wear item unless something went horrably wrong lol.
