Re: [bmw e28] Re: Heat and lots of it
I have a question for all of you regarding my
e28, 1986 528e. I have some ideas about this but am looking
for others input/ideas to help narrow things down. I have
heard about people geting no heat or little heat. My problem now is that I get all heat and nothing but heat regardless if I have the Temp. control knob all the way to the left or right.
What should I check first and has this happen to any one else.
Thankfully I can just use the outside air vent to regulate the air to keep things cooler. I also just had a new radiator put in and thermostat. The Temp. guage works (goes to the red if the hose blows(found that out before the new radiator ;-) ) and sits all the way to the left when the car is off HOWEVER it never sits straight up in the middle like I have read in some manuals it should. The mechanic says it's "ok" like that.
Not sure if any of that is realated,

Start with the heater monovalve. If you haven't
replaced it, its prolly
time. See realoem.com for pix. Its an easy R&R, its
right up at the top of
the engine bay, on the driver's side of the firewall,
four screws. The cheap
aftermarket version won't last long; The valve has a
very thin gasket in
there (thats what fails) and the cheap one fails MUCH
The usual failure mode is uncontrolled cycling, but I
could get my second
one to hang on full heat, so I could survive in winter
