I am in the process of changing my water pump and while removing the old one I noticed the bolts were rusted to hell and I really don't want to re-use the old bolts. Does anyone make the factory water pump bolts or will I just have to find some the same size and length?

ALMOST STOCK

The studded bolts, or both standard and studded?

both.. I don't wanna re-use any of them. I'm afraid they'll snap. They are in rough shape.

This is all the information I have in my "file" that I have collected from some users...

Water Pump Bolts:

The quickest and easiest way to get the proper timing cover bolts and water pump bolts is to buy two kits from www.totallystainless.com.

Timing Chain Housing Kit 302 EFI 12 pt stainless. #6-0847
Water Pump Kit 302 EFI Through '93 12 pt stainless. #6-0931

The above are just bolts, no special studs for accessories�

TotallyStainless.com does not sell a water pump kit for 94/95 5.0L.

If the prices above are a bit steep you can piece them together with the information below:

Autozone carries 3 of the odd sizes, which includes 2 studs and one long bolt.

http://www.autozone.com/selectedZip,.../selectZip.htm

The Autozone part number is 23744.

Bolt Dimensions for Autozone (Motormite Inc.) 23744 bolts:

Ford/Lincoln/Mercury Cars & Trucks 3.8L, 4.6L, 5.0L, & 5.8L. Includes 1 bolt and 2 studs.

Stud Size: 5/16"-18 x 3/8" x 16 x 5-3/8" and 5/16"-18 x 3/8"-16 x 3-7/16".

Torrie at www.fastpartsnetwork.com can get you many of the bolts.

Ford studs use 5/16� on the engine side and 3/8� studs on the accessory side.

From Helmut Roner for timing cover/water pump bolts for no p/s and no a/c:

Lowes Hardware:

One 5/16 x 5½ inch @ $.47, Item # 55819.
Six 5/16 x 2 inch @ $.16 each, Item # 63319.
Three 5/16 x 4 inch @ $.28 each, Item # 63322
One 5/16 x ? inch @ $. , Item # ?????

The last one I typed I don't have, yet. It should be 2-3/4 to 3 inches long. I bought a 2½ and not much of the threads go far enough into the timing cover. It's for the bolt hole that is between the two water ports on the upper left of the water pump. I'll have that info later tomorrow.

The bolts for the water pump pulley to be used without a belt-driven fan are 5/16 x 3/4 24-thread. The two rearmost cover bolts which bolt the cover to the block (not shown) are 5/16 x 3/4 inch. I am scavenging those from an ARP bolt kit that I have which can't be used with late model timing covers. Only a few from the kit could be used as the kit was designed for older model 289/302/351W timing covers.

Good Luck[/align]
