coolant leak at rear of motor

[lazlow]

I have a 2008 with mini max and 4" straight pipe. just today I noticed a puddle under the truck and its coming from the back of the motor. from what I can see its weeping from the top back and dripping down along the back of the heads then down to the block then oil pan. I've never had coolant puke out the degas but I got a faint coolant smell but that was a loose egr hose. I just got back from a 1500 mile trip with no problems and the truck is not beat on really. boost defuel is at 42 and I never go above wild. I've check my service manual and can't see any coolant related things at the rear. I don't suspect head gaskets weeping either. any ideas? sorry for any spelling I'm on my phone as I have not gotten internet back in jersey

Did you ever discover where the leak was? I noticed my '08 2WD is also leaking at rear of engine. Not much but any is too much. Last night I parked with front slightly uphill. I noticed a coolant spot under rear of engine. I could not tell where it was coming from but I did notice a drop of water hanging on some kind of shield about 2" in front of oil pan. I am already going to replace radiator due to a leak. Will delete EGR while I'm at it. Where the drop of water is located I don't think it is coming from the EGR so am doubting this will solve my new leak.

I ended up tracing the coolant back up towards around the head under the intake manifold on passenger side. Looking a little further i saw a drip somewhere by the egr valve/intake elbow. It was hard to see due to it not really staining the intake too much but the leak was from the egr and ran down the intake manifold to the head then down and out the back of the motor.

I ordered the performance truck products full egr delete with elbow and while removing the coolers they were full of coolant. I have a minimaxx so the valve was turned off and i didnt notice any smoke. Good luck with your truck and if your going to do the radiator it should make it real easy to find the leak if its in the front and the egr delete should be much easier with the extra room.
