Yes Just changed the anti-freeze and have been getting "Coolant Temp" Alerts
on my dash. The anti freeze is spilling out from the front left side looks
like through a relief valve. just below the hose going into the aluminum
casing for the radiator. scared to drive it. It runs hot. Whats going on??
This vehicle is a direct import from augsburg germany. One owner, 162,000+
miles on it. Runs like a dream until the above took place.
Why not just have your car towed to the nearest independent repair shop or
BMW dealership to have it examined by a competent mechanic. Then you will
know exactly what is wrong and can get it repaired. Its pretty obvious you
are not going to fix your own car, so get it done, NOW!
"Just changed the anti freeze." Did you change the thermostat too? It sounds
like you might have put the tstat in backwards and now it doesn't open
properly. The result is overheating.
Spitting out antifreeze is the affect of the problem you are having, getting
to the bottom of the Error Message will fix it.
The M20 has a bleed valve in the top of the thermostat housing - maybe the
M30 has the same thing? The radiator on mine also has a plastic bleed
screw in the top so that the coolant will get to the top of the engine.
I know from experience that if you don't bleed the M20 properly when
changing the coolant then you're asking for trouble from the inevitable
air-lock which will be in there.
I seized the engine, wrecked the pistons and warped the cylinder head
shortly after changing coolant for the first time on a BMW resulting in a
$300 repair job. A slant 6 can be a real learning experience.
must be. did not design that 1990 735i series, the anti-freeze is spilling
out of where I explained in my earlier posts.
hopefully I can do an internet search and get some photos of the A/C system
to confirm my suspicions.
the pressure stay up after you have switched off the engine?
Usually this points to a blown gasket. Cylinder pressure manages to get
into water ways and pressurise the cooling system, causing leaks and or
bursted water pipes. Hope for your sake the problem is less serious though.
If it is a blown gasket, make sure you have the cylinder head skimmed before
replacing the gasket. Actually, have the cylinder head checked out by a
specialist and overhaul it while you have it off.
