Spitting Out Antifreeze from Underneath? - BMW Forum

Ok Really weird, but hopefully someone can explain. I recently got my car re-built. New head new water pump timing thermo, radiator yada yada yada. Anyhow the car is not overheating and I do have heat in the car. But today I was sitting waiting for some girls to hop in for lunch. When I get back I noticed a antifreeze puddle in my parking spot. I looked underneath the car and there was antifreeze all over like it sprayed like a watergun or something.

Is this normal. I still have antifreeze in the overflow. I still have heat, and I have no overheating issue. Its almost like there is a nozzle underneath the car that says to much antifreeze and it spits it out. Does anyone know of this?

something might have blown, hose? gasket for the thermo ? etc . you have to track down the source of the leak somehow because you just recently had yours cooling system done there is the possiblility something wasnt put on properly.

Yeah I checked it. No hoses blown, and no overheating. Just like as if there is a nozzle that spit out extra antifreeze. I duno, I'll ask the mechanic see what he says. I'm just tired of going back. I finally got my car back, and I dont want to be with out it.

If there is too much water, it can come out of the expansion tank. Where is the puddle underneath the car? That is where I would start looking.

The puddle was underneath, when I shut the car off, if is as if it was a blow off valve for the radiator. It did not continue to leak, and when I check the tank it still had fluid not as full as I had it before but it had fluid. I had heat in the car and the car was not overheating. Any ideas. Someone said something about it being a overflow valve if you have to much antifreeze when pressure is built at its peak it lets it out. I was a Acura owner before and this really doesnt make any sense to me.

Were would this come out of if there is to much fluid from the radiator cap (its not) or rite underneath the radiator (were it looks to have come out rite be the driver side rim).

Most overflow valves are on the expansion tank. I would just keep monitoring it right now, since there doesn't seem to be an imminent problem. If it weren't for bad luck, you wouldn't have any, would you?

guys come on antifreez spraying under your car is never a good thing!

Well found out what it was. Dam car and its dam confusing cooling system. LOL. It wasnt a big deal, just had some air in the system that was trying to get out. My mechanic bleed the system for like an hour. Bubbles of air just keep coming out. Finally DONE!

Good to hear man!

Unless it's something obvious, the first thing I'd check is if the system is properly bled. These cars are the hardest to bleed of any that I have owned. Seems to take forever.

i second that tom.. they can be painfull.

Well it leaked again. I just dont get it.After having the entire thing re-built, I would think that they would change hoses and all, but no... So I dropped it off again at the shop. Explained, if I let the fan kick on once its warmed up, it wont leak but if I turn it off before the fan kicks on it drips from underneath the radiator. Seems to me like there is a leak in a hose or the radiator itself. So...
