ORD 9 SNL G-740 M38 parts list page 96 Cooling System Group 0503 Nipple, hose, 1/4" P thread. ORD# 7372808, WO# 649720, NSN 4730-00-737-2808. Note this is illustrated in Fig 05-2 as Item F in the water pump but the listing on page 96 says "Head". Just a slight mis-statement but I believe both are the same.

Maybe this help:
The water pump and cylinder head of the M38A1 has the same Nipple # 7372808, WO-645905.
See ORD9 SNL G-758,Sept1956, page 109:
2 pcs. Nipple, hose 1/4"-18NF pipe thd x1 1/4"
(cilinder head(1); water pump(1))
I can send a photo or drawing, let me know.

If all that's left are the old male threads wedged into the female threads then a thread chaser would work. If you have a solid ID of the nipple plus the male threads then a piece of taper square stock steel that will fit tightly in the remaining stub and driven it then turned with a spanner. Pre-soaking with a penetrant goes without saying and often times heat will help. _________________ Wes K
