5. Volvo C3 part# is 461162, unless your great uncle works for the SDF you, probably won’t find that pump. You can use Volvo part # 461094 from the civilian B30 on the same year 164 vehicles. You’ll need to press on and off the mounting flange to accommodate the military pulley and fan shaft. The spacing from the rear face of the water pump and the rear of the flange should be 102 mm. If you’ve swapped to electric, you can use the twin 10.5 mm lighter pulley off of the 164 and forgo the pressing. Be careful in pressing you can actually press the shaft out of position in the water pump.
