Ive got an 02 Sierra 2500 that shows a low level coolant message on the dash every 1,000 miles or so. I've done some research and I dont believe my engine falls into the problem with the head castings. Ive got the LS2 6L and I dont believe they were the engines with the problems. Ive changed the oil several times since I bought the truck and there are no signs of coolant in the oil. Theres no obvious leaks on the gound, and I dont seem to smell it being burned off, where the heck could it be going. I'm leaning towards head gasket thats directing coolant out the exaust port put I cant seem to see any white smoke or smell it. Any suggestions. Oh 210,000 miles, not sure if its the original motor or not.Read more at http://gmcowners.com/gmc-forum/newthread.php?do=newthread&f=2&kcplink=1
