Truck in sig, EGR delete (cooler and valve gone), diesel site coolant filter, and vegistroke (taps into the coolant lines on each side of the motor). I recently replaced the batteries in the truck ~ 1 1/2 weeks ago. The truck has been sitting for a week plugged in. I got home this weekend and swapped the FICM out on it (the one on it was bad), and usually when I do this, I undo the coolant bottle and just move it out of the way, so some of the soft coolant lines going into the bottle get bent, but they seem fine. I put the new FICM in, fired up truck and it idled in the driveway for about 10 minutes, all was good, no leaks. I drive 10 minutes into town and park. Some guy flags me down as I'm walking in the store to tell me my truck is leaking something. I think nothing of it as it's usually leaking some small amount of something... whatever. I come back to find a miniature fountain coming out the bottom of the truck. I open the hood and can't really see anything. I just drive it straight back home, and start looking more. I can not seem to pinpoint exactly where this leak is coming from.
It is definitely on the drivers side. From under the truck, the power steering pump is soaked and has coolant dripping off of it (definitely coolant, it's gold, and feels/smells just like it). from the top, I remove the battery on drivers side, the battery tray, the intake, the CAC tube, drain some coolant out, pull the large radiator hose going to the waterpump housing, pull the small line coming from the coolant reservoir to the waterpump housing and still don't see anything. At this point there is so much stuff covered in coolant I can not pinpoint it exactly.
There is a small tube that bolts to the waterpump housing that connects the housing to the 3/4" soft hose going to the coolant reservoir bottle. At first glance, I thought this tube was cracked, which makes perfect sense since I swap FICM's on a weekly basis, and I always just unbolt the coolant bottle and shove it out of the way, so that hose is constantly being flexed everywhich way. So I proceed to pull that little tube out, one 8mm bolt holding it in. Bolt comes out easy, tube does not (indicating to me that this probably isn't the leak point), get it out, inspect the o-ring on it, which appears good, and it doesn't look cracked, like I had thought. In fact it looks fine...
I'm still torn down to this point and not sure what else to look at... this leak sprung out of no where on me, and it seems worse with more RPM/more driving. Just idle in the driveway will drip, I kick it into high idle and the leak picks up a bit. Truck has 90k miles.
Any other places you guys can think of? Definitely drivers side and definitely in that area.
FWIW, the clamp that held the large radiator hose on the waterpump housing broke in two when I tried prying it apart, but the bottom side of that hose appeared dry, as if it was sealed good, so I'm not sure.
The plan as of now is to get a new o-ring for that tube where it inserts into the waterpump housing as well as a new clamp for the radiator hose. Might just go to a hose clamp instead of the spring clamp that was on there, but not sure yet. I'd really hate to put it back together like this and have it still leak. Very tough to pinpoint where it's coming from.
Any suggestions welcomed...
Thanks
