The bottom-most stud certainly requires one of these nuts as its location is shrouded by the WP's casting. Even with these nuts you must use an open-ended wrench as there is not room for a socket,</div><div class="gmail_default" style="color:#3333ff"><br></div><div class="gmail_default" style="color:#3333ff">Good luck--Michael Oritt</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, May 9, 2020 at 1:04 AM Michael MacLean <<a href="mailto:rrengineer.mike@att.net">rrengineer.mike@att.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">This is actually a three part inquiry. First, what size BSF die do I need to clean up the threads on a 100 water pump stud? Or, does anyone have a water pump stud in a jar somewhere in your garage? Two, I have two extended shoulder nuts to mount the water pump with, but which stud do they go on? Even with the extended nut, the stud closest to the angled tap (left top) does not have enough clearance for a socket. The two ribs of the water pump body at the bottom stud prevent a socket use with a regular nut. Does anyone else with a four cylinder car pull what's left of their hair out replacing a water pump or am I missing something?<div id="gmail-m_-6674846589287638381yMail_cursorElementTracker_1589000607518">Mike MacLean<br><br><div id="gmail-m_-6674846589287638381ymail_android_signature"><a id="gmail-m_-6674846589287638381ymail_android_signature_link" href="https://go.onelink.me/107872968?pid=InProduct&c=Global_Internal_YGrowth_AndroidEmailSig__AndroidUsers&af_wl=ym&af_sub1=Internal&af_sub2=Global_YGrowth&af_sub3=EmailSignature" target="_blank">Sent from AT&T Yahoo Mail on Android</a></div></div>_______________________________________________<br>
