I've not had heat in my 318is for about 2 years. I decided to fix that this winter, because the damn car is SO cold to drive I can't enjoy it. Feels like I'm driving an ice block.
So I researched the heater core and heater valve situation and I've replaced that + new aluminum pipes. Heater valve now operates as intended. Flushed and filled my coolant system which I've done about 30 or more times since I've owned this (damn) car - still no go on the heat. No overheating, needle is dead center at full hot. No warmth flowing through the pipes.
So I looked behind the engine and noticed that the coolant hoses look slightly impinged, but no heat coming to or from the heater core. So that could be troublesome.
I am going to remove my upper and lower intake manifolds and replace with new OEM heater core inlet/outlet hoses. Now that I've seen what the hoses look like, I don't think they are the original hoses. I think the culprit may be a blockage now in my secondary thermostat. I haven't yanked it out yet but the secondary looks to be quite pitted and who knows what the inside looks like. I know I may be able to probably clean it but - fuck it - I'll just replace it.
So yeah.. so much work to this car in the last year. Just want to drive this damn thing! Can't wait for summer.
