Loosing a little Coolant

[smuesse]

I found another problem with my truck. Tonight wile making adjustments to my new FBD exhaust system i noticed antifreeze on the Right side of the block around the starter. I traced it up some but couldnt tell where it was coming from. So i checked the EGR Cooler hose and the intake and the hose looked dry. I didnt touch it to see if it was wet though. From what i have read it sounds like that hose but it didnt look swolen or wet, it is orange by the way. I did block off my EGR cooler last night and today is the first time for me to notice the coolant leaking. When i had the Up-Pipe off i did stick my finger in the EGR cooler and it came back with oily stuff. Nothing that looked or smelled like antifreeze. Any one have any suggestions to what this may be?

I've not heard of the orange hose going bad, but check your connections, they may need tightening. It likely could be your EGR cooler is bad, but you'll usually get white smoke when it goes...

I was thinking it could be the EGR cooler since i had it opened up at the exhaust when i was capping it off. I havnt gotten any white smoke, i guess ill just keep my eye on it and see what happens.

My 03 is leaking coolant from the exact same area.....seems to leak overnight, but not while running (hot)....leaves a puddle about 6 inches square overnight....

The Dealer has looked for the leak twice, and couldn't find it....so, it's a leak I'm having to live with.....

My truck was at the dealer for 4 days before they were able to replicate the leak. It turned out to be the hose/fitting and was covered under warranty minus $100 Ded. It only leaked COLD PRESSURIZED OVERNIGHT. They tried and tried to tell me there was no leak and I insisted there was because the resevior went dry twice in a two week period. I hope this helps, it drove me crazy when they couldn't replicate it. The pumped up the system and left it overnight, in the morning the walked in to find a puddle on the floor finally! At least they didn't give up!

Thanks for the info!.....that sounds EXACTLY like the leak I have!.....

I'm going to print out this thread, and take it in (along with my leaky PSD) and have them look at it again!.....

Especially since my 5 years ends this April......(but only 65k miles)

What hose fitting was it that was leaking?

I checked my EGR hose over and its dry and so is the intake under it. I think its going to be my EGR cooler thats bad and leaking. I know i did a crappy job capping it off so its probably leaking. I just need to get a mirror and flash light to see if i can see the leak. If so i plan to totally remove the EGR cooler and re-route the coolant.

The EGR cooler hose.

I have the same prob with my 04.. It would never develop a puddle or drip it would just be wet in the same place It was also puking coolant out the reservoir.. and when i turn it off and get out sometimes i can here the coolant boiling in the reservoir. I took it in in nov they took 2 weeks to replace the EGR cooler. I noticed it was still wet and still puking coolant... I have been keeping the reservoir a inch below the min line since i don't have the update sticker.. I have been running hypertech stage 2 tuning and i have no other mods till 3 days ago when i put on a 4 in turbo back kit..

The shop called and asked me how my truck was doing i told them it was just like it was before they got it.. he told me to bring it in and have them look at it and i asked them if they where going to keep it for another 2 weeks and he just started making up excuses.. and i have not had the time to be with out my truck since then eather.
