Replacing the E30 Heater Core and Valve

[Court M3]

Did this yesterday and when you are prying the valve away from the core, put some paper towel or newspaper down, or coolant will leak all over your carpet.

Oh and on the square nuts superglue them in place on the new heater core to prevent them from falling out while trying to reattach the valve to the core

Is there a rebuild kit for these heater control valves like there is for the E28's?? Mine is shot and I need to see if there is a rebuild kit available.

The studs are a lot shorter on 84 and 85's. The seats do usually have to have the bottom trimmed off to fit securely. And even then its really close.

Good job on the lil write up. Lot of kiddos need to address this.

I am going to be putting heater back in this or next weekend. Windows fog way too fast if it rains outside ... shit.

It didn't strike you to yard out the DS seat, then just flop on your stomach on a carpet pad or some cardboard over the doorsill?

4 nuts/bolts & that seat is outta there.

Reinstalling the seats is a 2 person job in my car and I didnt feel like messing with its that much of a PITA. I dont know about other E30's with sport seats but the studs in my floor are really short, so short that I have had cut most of the "feet" on my sport seats off to get them in there. Those seats are probably the only original part of my car I have left.

And yes half of the job was working over the door sil with some folded carpet padding.

My center console is still out because I managed to loose one of the square nuts and I have yet to connnect the two lines to see how well it works. I could/can take a couple of pictures, you really only need one picture. The diagrams shows how everything goes together exactly as it is in the car.

Oh and then there is this picture

almost an upskirt there lol

Nice writeup, I'm planning on changing the two metal pipes in mine as they are pitting and have holes where the hose goes on...
