Car Forum / BMW Cars / January 2007losing coolant
Hi all I have noted this before in my head, as it seems a common problem, and now i think my car is sufferant from it. About 150 miles i get the coolant warning on the dash, i could never find a leak, athough for the first time when i was parked i found a puddle of water, i kept checking the oil to see if it was mixing, but no...so i guess its the problem where the radiator and the filler leaks from somwhere. The car is a 96 525i Auto Touring, done 270000 miles, me doing 6 in a couple of months of that. I do have a 92 or 94 520i, which im hoping to fix (a tyre blew and pulled me into the kerb just bending the front susp etc) I had thought of swapping them, but then im still in the same boat. I prefer the looks on this one and it handles better than the touring, although the extra bhp and torque makes a big differance. Can this leak be fixed, thats if its the usual place that people talked about (i dont know where) or can i get a aftermarket item. any info app cheers > Hi all > I have noted this before in my head, as it seems a common problem, and now > i > think my car is sufferant from it.

Oil in the water - forms a film in the header tank. Water in the oil - forms an emulsion a bit like mayonaise found around the filler cap. Water in the combustion chambers - white smoke. Oil in the combustion chambers - blue or black smoke. Air in the water - high pressure etc. All indicate leakage between the various galleries in the head and / or the combustion chamber. This can be caused by cracks, warpage, lost or incorrect head bolt tension, worn rings, burnt valves or failed gaskets etc.. >> > The car is a 96 525i Auto Touring, done 270000 miles, me doing 6 in a >> > couple >> > of months of that. 270k - not bad, but bound to be a bit worn by now! >> > I do have a 92 or 94 520i, which im hoping to fix (a tyre blew and > pulled [quoted text clipped - 12 lines] >> > any info app >> > cheers > >> > Hi all > >> > I have noted this before in my head, as it seems a common problem, and [quoted text clipped - 5 lines] > > the > >> steam is coming from.. will do, i can do it a couple of times on route > > Now i have a rough idea and can take a look, i took a few quick looks but > > saw nothing...and other times it was empty [quoted text clipped - 15 lines] > The AC condenses water as part of its normal operation.

Thanks, AC is new to me, cant see the point of it over here and i know when its running is uses more power/fuel > >> > i kept checking the oil to see if it was mixing, but no...so i guess > >> > its the problem where the radiator and the filler leaks from somwhere. > > Oil in the water - forms a film in the header tank. > > Water in the oil - forms an emulsion a bit like mayonaise found around the > filler cap. > [quoted text clipped - 8 lines] > incorrect head bolt tension, worn rings, burnt valves or failed gaskets > etc.. Yep, i havent noticed any at all and kept looking, no loss of power etc > >> > The car is a 96 525i Auto Touring, done 270000 miles, me doing 6 in a > >> > couple > >> > of months of that. > > 270k - not bad, but bound to be a bit worn by now! True, doesnt smoke, had a FSH and the week after getting it i toured E Germany and Poland in it without a hitch, never lost a drop of oil or water and just needed topping up a little after 3000 miles when it poppped up on the dash > >> > I do have a 92 or 94 520i, which im hoping to fix (a tyre blew and > > pulled [quoted text clipped - 12 lines] > >> > any info app > >> > cheers >> >> Follow your nose.

In winter - keeps car interior dry and prevents windows misting up. Nedavno R. Mark Clayton pise: | Water in the combustion chambers - white smoke. I have white smoke coming out from my exhaust. But coolant level is not changed. Is there any other reason that may be the cause of a white smoke? And since water can get in combustion chamber than you would probably get air in the radiator - high pressure?

It's an expensive way to guess where a leak may be. If normal methods fail to find it, have the system pressurized and dye added. Small leaks often just evaporate away leaving no trace without the dye. In my case the small leak turned out to be the water pump seal.

I have noticed where many leaks have come from over cars over the past 20 years, apart from the odd one where it comes out in a jet and hits somethings else...i will clean everything up and see if i can notice |
