87 735i faulty heater valve
My heater blows hot on one side (windscreen outlet) all the time. Local
dealer says it needs a new valve for ZAR 2931 plus labour (= GBP 245 or $ 450). My questions: (a) anyone know if the valve is easy to get at (or hidden deep behind the dash)? (b) is it worth fitting a second-hand unit? or (c) is the valve likely to be repairable? TIA John. -- *** Remove NOSPAM to reply *** |

According to what I see on Bavarian auto for a '87 735i it looks like you have vacuum operated valves. Those are a good bit cheaper than the electrically operated valve assembly used on later E32's ($49/US vs $149/US). On the later E32's the valves were mounted in the engine bay on the left side against the firewall. Dunno if an early E32 (which and '87 should be) has them in the same place. With vacuum operated valves it could be that you just have a broken hose. Do you know if that's been checked or if your mechanic is just assuming the the valve is bad? -- The instructions said to use Windows 98 or better, so I installed RedHat. |

I'll check hoses and/or wires first. J |

I may as well take it off and see if it's repairable before shelling out $450 just because BMW believes in a 'throw away' society. J. |

Four small screws on top? That's it. Be prepared for coolant spills. *After* you get it off and get those screws out, Jenny Morgan (BMW CCA's Roundel columnist) recommends that you *replace them* with either bolts or phillips screws. I think you'll know why when you get them out. -- C.R. Krieger (Been there; hate them) |
