coolant overflow tank, need help

[cosmicbluejosh]

ok i did a search and didnt find the answer i was looking for. my coolant overflow tank keeps draining all the fluid out of it. there is no leak as it was fine last week and i checked the hose for a leak, but on the weekend i installed the coolant sensor for my turbo kit which connects to the back of the engine on one of the hoses there. ever since then ill fill the overflow tank and it will be fine all day, but when i come out to the car in the morning all of it has leaked out. i check the radiator every morning too and it is full. im not overheating. its got me a bit stumped. any ideas or suggestions? thanks.

you may have a leak somewhere else. I had the same issue with my mustang. it developed a small leak on the thermostat housing that i already put on a new 180 deg one and gasket. tightened the bolts a little more and the leak was gone. check ALL rubber hoses and radiator for leaks.

ok thanks ill check the thermostat housing and hoses.

Check and see if where the hose from the overflow is loose or all crusty where it meets the top of the radiator under the cap, you may need to cut off an inch of the tubing and push it back on.

Same thing happened to me! but like in a day the coolant was gone 0.o some dude put Water instead in there and it seems its not leaking anymore, the only weird thing is the coolant tank got like brown like rust color (boom07)

Oh i almost forgot!. The hoses that go to the throttle body are often neglected and the passage on the tb sometimes gets obstructed with crap and corrodes away. I bypassed mine cause of that. I've seen this on many vehicles.
