This thread popped up first when I tried searching for a solution to "
stripped water pump bolts 4.0L"...
Mine is a 4.0L SOHC [2-door Explorer Sport] and I replaced my original water pump literally four years ago...
AND I barely got 30/40K miles before it started leaking...
I got a deal on a "Magneti-Marelli by MOPAR" brand/version water pump so I went with it...
I guess I got what I paid for...
This time I just went to Autozone & paid retail for a replacement.
Anyway, a month later it started to leak too. So I found the bolts seem to have backed-out or sorta loose.
BUT when I tried re-tightening the second bolt to the right of the top nozzle/nipple [connects to the thermostat], it STRIPPED OUT before I had a chance to torque it.
Plus the bottom one right below too!
I replaced the other "10" bolts with
longer M6-1.00 x 25MM hex-flange bolts
Stripped out holes, I went with
1/4-20 x 1inch with two washers for the top bolt & one washer for the bottom bolt.
SO FAR... It's holding... but time will tell.
