Water Pump Bolts?

Does anyone have the bolt size/lengths/threads for the waterpump?

I need to this information for both bolts that hold the waterpump on. I can't find any information searching.

Thanks for any input.

What body, XJ? Year? Engine?

My 4.0 has four bolts, one long and three short.

5/16-18
Short is ~1 1/8", long is 1 3/4". Probably the same for all of them, but this is from the 97-99 parts book, lists the same bolts for 2.5 and 4.0 engines.

Thanks for that.

I forgot to mention its a 1995. Not sure if those bolts are different.

Most (if not all) of them should be threaded 5/16"-18, and I think they were SAE all the way up.

I would probably use brass, bronze, or CRES to control corrosion - if they're not available, simply coat the carbon steel screws with RTV black (which helps them seal and helps keep them from rusting.)

I don't recall anything about the lengths. If I have the information, it's probably on my site (www.kelleyswip.com/tech.html, follow the links,) or you can match the lengths underhead (if you have an alternate way to the hardware store.)
