Water pump

Yup. The engine was rolled forward to get easier access to the rear half of the engine. I took that picture just before I took off the front head. You can see that the rear head is already off (look for the 3 piston circles in the back). My next step was to remove that strap and take off the front head as when you do one, you do the other.

When I rotate my engine forward, I use the mount on the engine for that purpose, then either hook it to the framing member that the mounts get bolted to, or through the hole that the hood latches into. I have two different straps, one with a hook and one without. The one with the hook is the easier to use since I don't have to make a complete loop, but which ever one I find first is the one I use.

Here is another photo of where the hole is, looking straight down on the engine. The hole the o-ring will be at is in the lower left corner, just above the bolt you see, between the two wires.

(side note: that's actually the same head as in the other picture, just cleaned up. I thought it was amazing how much crud and varnish had built up on it.)

Well thank you very much for all of your help. I think my water pump job will go relatively smoothly.

Thanks again.

I bought the pump today. I went to an aftermarket supply shop. I looked at a rebuilt from Fel-pro and a new one with a lifetime warranty. I actually went with the new simply because the mating surface was machined smooth and the rebuilt had the casting texture.

I bought some permaflex sealant for the gasket but was wondering if I need it or if I should use something else. I have never used sealant on gaskets before including water pump and thermostats unless I wanted to "glue" it place for assembly ease.

I also bought some de-ionized water. I have always used tap water and I know that there are minerals in tap water. In fact someone once tried to tell I should look at the scale that forms inside a pipe. My thinking was that the only minerals from the tap water would be what was in the original 2 gallons. (There is not a constant flow of new water as in a pipe so that analogy is flawed imo).

Do the bolts need to have a sealant applid to the threads?

That's all I can think of for now.

Thanks

A bead of RTV I beleive is all that is called for in place of an actual seperate gasket. I can check my Haynes manual if you don't have one later. The coolant system isn't under high pressure so doesn't take much to seal the surface.

Using deionized isn't absolutely necessary, but isn't going to hurt. If you have "city" water, mineral content probably isn't going to be high enough to cause any problems. If you have hard or well water, then using deionized water is probably recommended.

The bolts don't require any type of lock tite or other sealant, although a low or medium locker isn't going to hurt if you are paranoid.

Thanks CDRU. Sorry for asking so much. I actually have a gasket. It came with it but the instructions mention someting about dressing the gasket which is something I have never done in the past.

[cdru]

You are correct on the gasket. I read my manual and there is one. I just had forgotten about it. Dressing the gasket is just spreading a thin layer of RTV on both sides to help it stick and fill in any slight imperfections between the two surfaces. So just put a few dots of rtv around the gasket and spread it around with your finger on both sides to coat everything evenly. Then quickly install it while it is still wet/tacky.

I knew I would come up with 1 more.

It looks like the pump can be oriented in any direction. Should the weep hole be at the top or bottom???

[KJRich]

Bottom.

Well I did the water pump today. It was relatively easy. I wasn't really sure if it was leaking through the weep hole but the bearing was making a noise. It almost looked like it was leaking around the gasket.

In any event I replaced it. I want to thanks those who offered answers especially CDRU.

If I can add any words of wisdom for the next person:

The water pump mounting holes are not evenly spaced. It looks like they are and I didn't find out until I had the gasket coated with sealant (and on the wrong side of course). But all went well just a bit messier than I had hoped.

I wondered about that when you asked if the weep hole when up or down. I had thought that the mounting holes were slightly off so that it really could only fit on there one way. I wasn't sure though and I couldn't tell from the picture of the water pump I found, so I didn't speak up. Oh well. Glad things went well.

I have the same problem as you did. Coolant droplets just fly around the pulley, radiator hose, and radiator. Can you tell me how you fixed your problem?
