Posted: Sun Jan 12, 2020 9:30 am Post subject: Water Pump Rebuild
Can someone out there help me find the manual reference for rebuilding the water pump on my a1 ? Ive been trying to search this site but i never seem to be able to find what im looking for.
And a big shoutout to the moderators, thanks for doing this for us we appreciate you.
The details are very accurately covered in the M38A1's engine manual TM 9-8015-1 pages 85 thru 89.
There is no reason you should not already possess all applicable M38A1 manuals since we supply all of them in PDF format on our downloads page for absolutely free.
I try to send all new members that tell me what model jeep they have a copy of our survey form for that model and a copy of publications available for that model.
The List of M38A1 related manuals: ( you needn't collect all of these but you should keep your eye open for copies that can often be found for free or very cheap. The basic requirement for manuals is easily satisfied with our downloads page.
