Coolant bottle/ Spring Torque specs

Went to drive the truck yesterday and found a huge coolant puddle under the motor, I traced it back to the coolant bottle it looks like it was coming from around the outlet nipple on the bottom. I pulled the bottle today and i cant find anything wrong, the hose looks good, and I cant find any cracks in the bottle. I even tried pressurizing the bottle and the cap bleeds off when it gets the a certain point (i think 16psi) like it should. Im stumped, the only thing i can think of is that when its hot the plastic separates and leaks,IDK im at a loss. Any Ideas? is it possible that my cap is messed up and doesn't always work right?


Also Im replacing the front leafs on my truck with x codes, does anyone know the torque specs for the U bolts, leaf bolts, track bar, sway bar, etc? Ive done a bunch of searches and everyone has a different answer.

Have you tried pressurizing the whole cooling system, either with a manual pressure pump and fitting or running the truck hard for a little while to get the pressure up there. The OEM cap is known to be faulty, I think they've changed the design, but Ive had good luck with the Stant cap. Is this on the 99 listed in your sig?

No EGR on the 7.3 and head gaskets are extremely rare on these. Im probably going to order a new bottle and cap, see what that does. i can hardly see through my bottle because its so faded and stained.

Well if you figured it was coming out of the nipple out the bottom did it leak when your pressurized it? Sounds to me its coming from somewhere else, pressurize the whole system to make sure its not leaking from the rad hoses or water pump. I wouldn't buy a new bottle honestly and it sounds like the cap is doing it's job..the caps were the problem on the 6.0s not the 7.3.

The Bottle didn't seem to leak. When I first found the leak I followed it up to the highest point and that was the bottom of the bottle. Its possible that it came from somewhere else. Anyone know the best way to pressurize the whole system? I'm guessing just drive it.

Well I finally got around to borrowing the pressure tester from work, and I found the leak! Like I suspected there was a crack in the coolant bottle, it was where the two halves of the bottle are glued together. Time for a new bottle!.

I still haven't found the correct torque specs for the front springs.
