I've read and reread water pump parts numbers in the FAQs and some posts in this forum. I just want to be sure what the best high output water pump is for my 1993 application. My best study via parts available for 1993 K3500 (it's a 1994 class a RV pusher with the DB2 pump) is a part number 88926231. Other part numbers in the FAQs are

Single thermostat:AC Delco:# 13191,12559338
Dual thermostat: AC Delco:# 131103,12559336
  • Napa: 44042
  • 4 Bolt 130 Gal/Min AC Delco: 252717
  • 4 Bolt 130 Gal/Min OEM: 88926231
I really want a high out put (130 gal/min) pump I think.

Okay, I know this is opening up the can of worms, but what is my best option for a pump under 150$?



Next question. 190 or 195? Mine is a single T stat setup. Again from FAQs:

Thermostat:

  • GM: 12559338 (190*F 1994-1995 Single T-Stat)
  • GM (195F for dual t-stat): 12559336
  • AC Delco (as above): 131103
  • AC Delco: 13191 (190*F 1994-1995 Single T-Stat)
  • AC Delco: 12T45E (195*F 1994-1995 Single T-Stat)
Thanks gentlemen, I'm getting close to having this thing in :)

Single Stat, AC/Delco 190*
Napa 44042 is a highflow pump and is a direct bolt up replacement
