2006 Hyundai Tuscon Coolant Loss

you see nothing on the ground when the car is parked in one spot overnight or all day? have you checked the oil to see if it looks milky of foamy? does the heater work good and blow hot air? any steam coming out of the heater ducts?

No leaks, heater works fine,car does not overheat as long as I keep the coolant level ok. No steam and no leaks noticed. The oil looks OK to me and the dealer thought the same. Hence the mystery

have you checked the transmission fluid level to make sure that it is not over full? are either side of the floor boards getting wet? check up high under the dash on both sides to see if the carpet is getting wet.

Thanks Carpet is fine. I will check the tranny fluid

PULL YOUR PLUGS (KEEP THEM IN ORDER AS TO THE CYLINDER THEY CAME FROM) AND COMPARE THEIR COLOR

IF YOU CAN SEE THE TOPS OF THE PISTONS---SEE IF ONE (OR MORE) HAS A SANDBLASTED TEXTURE (THEY SHOULD BE SMOOTH OR SLICK)........SOME PLACES HAVE A MINI-CAM THAT MIGHT SEE THIS THRU THE PLUG HOLES

AN SLOW INTERNAL HEAD GASKET LEAK INTO A CYLINDER CAUSES "DETONATION".....THIS GIVES IT THE "SANDBLASTED" OR "PITTED" LOOK

I HAVE A '46 JEEP THAT THIS HAPPENED TO A FEW YEARS BACK (MINE WAS RUNNING FINE TOO AND UN-NOTICED......UNTIL "DETONATION" BROKE A TOP RING (THIS WAS IN MY CYLINDER 4)....I STARTED HEARING A TAPPING

I INVESTIGATED EZ STUFF 1ST---THIS IS A FLATHEAD, EZ TO WORK ON---I DROPPED THE PAN AND IT WASN'T MY BEARINGS----THEN I PULLED THE HEAD.......IT WAS OBVIOUS #4 HAD A PROBLEM

MY OLD PISTONS ARE AT MY BUDDIES HOUSE ( I FAILED TO TAKE PICS OF THEM THUS FAR)....BUT I WILL SOON!

I DO HAVE A PIC OF THE BOTTOM SIDE OF THE HEAD---LOOK AT #4s COLOR !!!

I REPLACED ALL OF MY BEARINGS (SINCE I WAS IN THERE) AND ALL 4 PISTONS......SURFACED THE HEAD AND A NEW HEAD GASKET.......I SPENT LESS THAN $300...........WHEW!!!

KEEP US POSTED ON PROGRESS

THE MEDIC

Tranny Fluid is fine. It snowed yesterday. So I ran the car and then let it sit over night after I place snow under the car. So i did find some drops on the ground in the snow in front close to front driver side wheel. I could not see where it came from just where it landed. Wants much a few drops only a small % of what I am losing. So I assuming its probably hitting somewhere else evporating and then whats left is hitting the ground

I am having the same problem. I noticed mine during the summer while traveling. After driving a couple of hours, I had the AC on low and it was still not cold. I stopped for a break and when I started the car again and turned on the AC, small ice pieces blew out of the vents!?!

Any ideas, thoughts, suggestions?
