Engine Cooling problem
2003 Chevy Suburban V8 Four Wheel Drive Automatic 80,100 miles
My 5.3l 1/2ton Suburban shows a very small coolant leak. When I crawl under the truck and look at it, I cannot see anything wet. When the puddle occurs, it's very small (about 1 - 2in. In diameter). I can go days or weeks w/o seeing any fluid on the ground - and then it's there again. When I'm laying on the ground and looking up, I can see a red-orange discoloration on a wiring harness - which would indicate something is leaking on the wiring harness, the leak is following the harness and dripping off of that at it's lowest point. The harness is on the passenger side is in the vicinity of the air compressor/trans. Fluid lines that follow the passenger side of the oil pan. The coolant tank itself has dropped 1/4 - 1/2 inch below the 'full mark' - and I topped off the tank back in January when my dash displayed a 'low coolant' msg (my first indication of trouble). Whatever it is - it's a really slow leak. I'd like to get it repaired before it gets worse. Any ideas?
