Norway Posted January 22, 2014 Share Posted January 22, 2014 I usually keep truck my truck indoors and the heat is set to 45. A couple weeks ago I had to leave outside. We had a cold snap, it went a few degrees below zero for a couple nights. I went to check on truck after 3 or 4 days when it warms some ( 20's) and there is a 2" puddle of antifreeze under it. I traced it back to a wet area inder the crome injector shield between the 1st and 2nd injectors.I dried it up and it hasn'n leaked since. We've had some cold and now were back to below zero. After a few days of 30 and 40 degrees weather, I started her up and let it run for a couple hours ( various high rpms ) and no leak ?In the picture where the red circle is is where it was wet and dripped to floor. I couldn't have lost 2 ounces and if it wasn't on a concrete floor I never would have noticed it.I know my antifreeze is correct whth 50 / 50 blend.I'm writing in because I've got no idea where this could have come from on this side of the engine. I'm looking for ideas and imput as to where this could have come from ?Thanks Rob Quote Link to comment https://www.bigmacktrucks.com/topic/34343-granite-anti-freeze-leak/ Share on other sites More sharing options...
farmer52 Posted January 22, 2014 Share Posted January 22, 2014 Is there a hose clamp near? I have seen clamps "loosen" in extremely cold temps. Now that I mention this I need to check the MH and my tractors...all are in the "deep freezer".

Norway Posted January 22, 2014 Author Share Posted January 22, 2014 No hose clamps. I do most of the general mechanics on truck and she really tight. I'm concerned that it could have puked out the head gasket or from under the injector ?Are there any bolts for the injector or anything else that pass thru coolant up front on passenger side ?Is there a weep hole on the water pump ? Could that have migrated around the corner ?Rob Quote Link to comment https://www.bigmacktrucks.com/topic/34343-granite-anti-freeze-leak/#findComment-228126 Share on other sites More sharing options...
br549 Posted January 22, 2014 Share Posted January 22, 2014 about 1/2 " above the red circle is that a hose clamp? On our 2005 ac engine there is a steel tube from the air compressor that comes to there and a short hose and 2 clamps and than steel tube around the water pump housing.

Norway Posted January 23, 2014 Author Share Posted January 23, 2014 That black tube in the circle is the wireing harness. Air compressor is below this area. However the info about the aircompressor line is great. I will look at that hose anyway. There are some burried items on the engine and unless pointed out you'd never know...Rob Quote Link to comment https://www.bigmacktrucks.com/topic/34343-granite-anti-freeze-leak/#findComment-228215 Share on other sites More sharing options...
Mackpro Posted January 23, 2014 Share Posted January 23, 2014 Right above that EUP harness there is the air compressor coolant steel pipes. A short piece of hose connects the two pieces of pipe. The Mack part # is 160AX570P3. Its a silicone hose and holds up the the heat very well. Changed one yesterday and the workorder was still on my clipboard with the part #.

Norway Posted January 23, 2014 Author Share Posted January 23, 2014 Thanks for the info. I can't get to it right away but that seems to be the problem. I'll end up changing all those hoses on that line. I've been slowly replacing all soft lines a little at a time.Regards Rob Quote Link to comment https://www.bigmacktrucks.com/topic/34343-granite-anti-freeze-leak/#findComment-228262 Share on other sites More sharing options...
thomastractorsvc Posted January 23, 2014 Share Posted January 23, 2014 More than likely it was shrinkage as it only happened when it was left out side for awhile. Antifreeze will go where water and oil won't meaning that it is a smaller molecule, if it is not leaking and shows no sign of a leak other than that small puddle I would not worry about it. The freeze point is good with mix and the line is not leaking when running, it was probably a shrinkage issue. Quote Robert"I reject your reality and substitute my own."
