My block has the water outlet port in front of the blower (it was used for the spark ignition pre-heating device on the NATO engine) so I am going to presume that the block will fit the aftercooler for now. Reading my manual it seems I need the aftercooler itself, the water outlet tube, the water inlet adaptor, a gasket set, some special bolts with locking patches, and that's about it. I would also need to figure out where to connect the water outlet tube to, since my engine has a coolant cross pipe between the two thermostat housings where the manual shows the coolant outlet pipe connected to. I suppose I could fabricate a tee-section into that cross-pipe, I can fabricate a coolant outlet housing out of aluminium to fit over the coolant outlet pipe of the aftercooler, and I could fabricate the water inlet adaptor too if it came to that, but I would prefer to find the pieces. No where is the air diffuser for under the aftercooler mentioned in the manual.
So - anyone got some spare parts sitting in their shop?
