Ok so yesterday i was flushing the system and i went to put the coolant bolt back in and it broke. The head snapped right off, and it in there pretty far. I was wondering if this has ever happen to anyone and how did you fix it? Also looking for some insight on how to get it out. Im not sure but im thinking about getting a set of left hand drill bits and doing it that way. waht does everyone think?? Thanks ahead of time guys.

 

does anyone know the part number for that bolt?

 

Upper or lower bolt?

 

the lower bolt on the water pump. the one with th "C" on it that drains the coolant.

 

That's the bottom drain bolt (there's another one to drain the cylinders, if you really want to drain/flush the system, you need to remove both).

The waterpump drain bolt is 90121-MV9-670, the sealing washer is 90463-ML7-000.

The upper drain is a real pain to get to, did mine about a month ago and would love to never do it again.

Torque is only 9 ft/pounds.

 

Thx for the part #'s. I didnt know about that top bolt. So i take that out too and reflush my system??. If so no biggie since i have to get that lower bolt out. thanks again for your help.

 

Here's the way I've done it on my 600 and the 954:

I remove the bottom bolt, let it drain, then the cylinder (upper) bolt, drain some more. I loosely screw in the lower bolt and run distilled water through, it will ultimately come out the top bolt hole. Then I release the lower again, more water comes out. Do this a couple of times to guarantee the system is flushed. (If you're replacing the antifreeze with fresh antifreeze you don't have to do all the flushing with water. I was replacing the antifreeze with water and redline, so I needed it cleaned out of all the green stuff).

Replace both bolts with new sealing washers, fill it up (including the overflow tank to the upper level line). Start the engine, let idle 2-3 minutes, snap the throttle three or four times to bleed the air out. Refill everything as needed.
