No Heat!

[chap0223]

Alright, new to the forum, and I have minimal heat in my 87 325e. It's weird, I have hot heat at a low fan speed (1 or 2) and if I turn the fan up any higher the heat slowly dissipates to cool air. I took it to the dealer and they ran a bunch of tests to verify the operation of the heater core, radiator and heater control buttons. I changed the thermostat, the auxillary t-stat (recall for burning legs), water pump and radiator hoses. Obviously I bled the system after these changes, and added new coolant. What gives?

Sounds like your heater bypass valve is screwed up. You may have to change it.

any tips on how to easily remove this valve ???

Easy, it's found just above and to the right of your gas pedal. Drain your coolant all the way first or you'll flood your floor with coolant.

well, i was at the yards the other day, found the valve, but was only able to get to the 1 screw facing me.
odd as the others faced firewall and it seems that valve would dismantle instead of dismount. what should i look for ?

3 or more Phillips screws, ?
did you used a stubby screwdriver ??
is the valve a integral part of that whole plastic piece ???

thanks,
Frank

You remove it as a whole. Remove the center console, then take out the philips head screw of the retaining bracket nearest to the fire wall, then remove the (normally 8mm) head screw going into the heater bypass housing with a 1/4 ratchet. The rest is self explaining.

But before you rip your car apart you should check the hoses on the engine side for kinks and pinches first.

I'll give it a try next week.
