I am restoring a '92 SPI and was a bit confused where all the cooling and heater pipes went and what they all did.
I decided to find out but soon found there does not seem to a diagram available (or I could not find one) so decided to make one.
If anything looks wrong please let me know and I will correct - Hope this is useful - Please share as you wish.

Brilliant, I was looking for a schematic the other day. Thanks for sharing.
One Carb Or Two?

To drill down even deeper, would be great to have these labeled (maybe they are but I can't see) which pipe the house hookup to on both the intake manifold and the heater matrix. I guess you could also add which hole the go through on the bulkhead as well. I always wonder if it matters which go where or which is more efficient.

Hi.
The hoses have labels, they are a bit small. You can save the image to your computer and zoom in as required.
Looking at some photos, the hose from the heater control valve goes through the left hole in the bulkhead when looking into the engine bay.
Looking at a flow diagram from an MPI the heater matrix inlet nearest the bulkhead is the outlet The other of course is the inlet.
I don't know which manifold pipe is inlet and outlet but following the logic of the radiator and have the inlet at the top and outlet from the lower - but I guess like the heater matrix, I don't think is really too critical but will stand corrected if wrong :)
