Okay engineers, a question for you

The water pump pulley-wheel is fixed to the pump with x3 Torx or Spline screws, I can't remember which. It looks a little like this:



All of them look a little corroded, so I am considering removing the water-pump from the block, then drilling out the pulley-wheel screws and replacing them with nuts and bolts with a good allowance of locktite.

Are there any issues with me doing this?

I should point out that I need the pulley-wheel to go on to the new pump.

i would imagine that bolts with spring washers will suffice ..

No issues, providing you have clearance for the longer bolts.

Seems overkill if they're just a bit corroded, though . . . could end up being an unnecessary can of worms.

Can you not just re-tap the holes and wire-brush the bolts ?

Yes, there is quite a bit of space.

The bolts / screws are the problem, I think I will have to get the pulley in my vice and drill it out as the head seems 'fragile'. One of them is not rounded though.... Yet! I noticed it seemed to be giving and not in a good way, so I stopped attempting to take the pulley off in situ with the engine.

Then I thought that bolts and nuts would be much more secure and better should I have to remove it again

Fair enough - so not just corroded but actually pretty fooked.

Yeah, go with bolts, nuts and spring washers . . . I'd suggest you'd NOT want to use Loctite . . unnecessary, IMHO.

Decent set of spring washers, jobs a good'un.

Haven't got any photos of the final install, but when we upgraded the cooling fan and radiator on the Mustang we just pulled out some some stock ?UNF bolt and spring washers.

Loads of space in there! At least they thought about servicing when designing the car

I was thinking about finding a pulley to have as a backup in-case the drilling out of the screws does not go to plan.

I found the exact same pump for the same engine on eBay, yet interestingly, the fixings are bolts:



Which makes me wonder if a previous owner had the pump off at some point and replaced mine with screws rather than bolts, or the other way around.

I'm getting a bit lost in this, using terminology such as screws and bolts.

So your pulley is bolted on to the propellar shaft of the pump. That is via threaded holes on the shaft, with no nuts.

You're planning on taking the whole pump off, drilling out the bolts, then replacing the bolts that have been drilled out with bolts and nuts?

Is that right?

Cunning Plan

Ah sorry dude!

Right, when I say, 'screw' I mean a bolt with a spline-type head.

I cannot find a really good picture of it right now and I can't take one (in the office), but it is quite similar to this Torx one:

you sorted it yet ...


Nope

I'm off from December 16, so I can have a good look then. In fact, it is hardly seeping at all now, so I am wondering if it is wise to disturb it at all...

you have two options...


1- if its not broken leave it alone...

2- if its not broken keep on fixing it ..until it is....
