ok so about every two or three weeks im having to add coolant in my truck. I have tried really hard to trace it down and cant find a leak. It does not build up high pressure in the cooling system as if head gaskets were leaking. Does not smoke or blow out water vapor. it does not leak on the concrete so ?????????? Any suggestions?

Please define "hard" upper Rad. hose? After a water pump change out, I checked my this morning and it was colapised? WTF?
Pull glow plugs, pressurize system over night with airline,10-15lbs NO MORE THAN 20lbs. Check to see if coolant in cylinders. Either a head gasket or injector cup.
Thanks for all your help, How difficult is it to pull the glow plugs? and do I have to pull all 8 of them? I am assuming you mean to pressurize the cooling system through the bleeder valve ontop of the thermostat housing correct? How is that achived? I can get air in there but how do I get it to stay?
No injector cups on lly. Have you checked the oil for any coolant? Did you say you just did the water pump?
Mine had the same slow loss. There was no coolant on the garage floor and didn't seem to be any leak. Only way to see it was by taking the plastic pan off and looking up from below with a flashlight. There was a small dribble from the water pump. What came out while the truck was sitting landed on that plastic pan, then driving blew it away. Probably more came out with speed but it would get blown away too. As it gets worse there'll be coolant dropping down when you stop, especially on a hill.
Yes I just finished the water pump change out. I drove the truck this afternoon and seems to be running ok. I will keep an eye on everything to see what new develops. I would still like to check the cylinders for coolant.
Lol I just noticed there where two people. My bad. :screwy: I get confused sometimes. I hope for both of their sakes its just a water pump. HG is no fun.
The only symptoms I had when my pass side HG went out was pressure in the cooling system, and running a little bit warmer than usual. Only way I could tell which cylinder it was is because that piston was cleaner than the others. You may not find any coolant in the cylinder.

Shawn,
Are you sure you got all the air out of the coolant system after you installed the new water pump? The reason I ask is there have been some other guys on here that have had a similar issue but it was due to air in the coolant system.
Also some of you guys have said before (and correct me if I am wrong) if the HG is blown, you should be able to smell coolant in the exhaust or get it on your hand if you put your hand over the exhaust.

Thank you for the heads up. I have now logged about 300 miles on the truck and everything seems to be fine for the time being. I may have had airin the system which cause the concern for the lose of coolant. :hug:
I'd sure like to know this. Mine's leaking and dripping off the idler arm. I'll have to go and see if it's coming from the tailpipe
