Hehe, reminds me. we got these V12 C32 caterpillar engines installed.
After 500 hours this massive coolant tank on the front had a crack. So myself and another fella spent 6 hours changing out the 250lb pig of a tank.
Anyway I hate these new engines, 25 coolant lines and apparently 150 bolts go into this thing from all different angles.... Tighten one bolt more than finger tight and none of the others will fit in. What a pain in the butt.
So after the 6 hours of changing it out we install the new one, fire it up and as soon as it got hot, it had a leaking weld. Cat refused to weld it in place, they wanted us to pull it back out and send it off and they'd give us a new one.
I got pissed and hit the leak with a hammer and it stopped leaking.
That was 22,000 hours ago.
The End.
