I've been searching and can't find the answer. Hope someone here can help.
I have a '99 model truck(see sig) and it has the "one big nut" water pump. Is this the 'good' HO pump (like Heath sells) or do I still need to check the part number? It has a number on it but I can't really read all of it. Ends with ...5717 I believe. Can anyone set the record straight for me?
 
It's the good one..If it's factory GM or a quality replacement...I did a thread on Chinese Knocks offs not lining up but otherwise..yeah you got the good one.
 
Of course, right after I posted I searched for something else and found a thread that told me it was the good one! Mine is the original pump (with only 290K on it!) but I'm planning to put it back on and see how long it goes. Maybe a bad idea, but my funding requires that i make certain cuts!
