Please read this quick while I have it apart

Chris, Daniel's suggestion on cleaning your engine and components is a good one. We do that on our log loaders all the time. It makes it much easier to trace leaks whether they be coolent,oil or any fluids. Another thing that sometimes will tell you where a leak is-is to pad the suspect part with absorbent pads. Be carefull when doing this especially with oil leaks and a heat situation. sometimes they are just time consuming to trace down... ... Good Luck

I did... I scrubbed my hole engine down last night with Gunk and the purple stuff for the more sensative areas.



Well guys, I put it all back together... and it's STILL LEAKING!



BUT: Now that the engine is clean, I have noticed that there is moisture under the weep hole on the water pump... I'll keep an eye on it.



In the mean time, I have the idler pully assembly out so I can get a new one in the morning. Plus I have the starter apart so I can install the Larry B kit and have a local machine shop clean up the armature.



THe ol' girl is getting some MUCH needed maintenance. And besides, the engine has never been cleaner!



I hope to be done tomorrow... I wasn't able to get started on the governer spring... It at least has to be running so I can pull the front of my truck into the garage... our driveway is shale, and I'm a butter fingers...

I was loosing coolant for about 6 months, before I finally found where it was going. I started my truck one day and was tinkering around and looked underneath and a stream was just pouring. The waterpump finally let go. I would certainly check there and if it is leaking much the fan and air will blow it everywhere making it hard to find. I think the waterpump I got was around $35.

Well... now that the engine is clean, it looks like it might be the water pump.



I am going to say this again, as I have many times before DO NOT ever go to Salmon River Motors in Salmon Idaho. They ripped me off, lied to me, and did TERRIBLE work. They treat there mechanics badly and they are all leaving because of there poor treatment. This water pump that may be shot was supposed to have been fixed by them a year ago... and it took them 3 trys to turn my rotors correctly, one of those times they didn't even try... and several other bogus jobs that were supposed to have been done before I picked up the truck when I bought it.



Ok, now that I'm off my box...



When I get the ol' girl all put back together, I'm going to put a chunk of sponge underneath the weep hole and see what happens.



Thanks guys.

Don't feel bad CB, I'm in the same boat as well. I can definately say that it's comming from my thermostat housing. I've tried everything I could think of to seal it up without major modification, which seems to always fix the problem until I pull the next major hill and it will start seeping again. My next plan of attack it to have a machine shop mill the engine hook flange and thermostat housing down some to allow for the installation of paper gaskets. I guessing that is the reason why Cummins always puts that blue plastic gasket pattern with every new thermostat they sell. I can add this as well, on engine side of my engine hook flange, the supposed machined surface is not exactly flat, but is slightly rounded. The other side looks perfectly flat. Weather I use RTV silicone or not, it always seems to leak at that rounded part of the whole works.
