Now with the engine and transmission installed, left to do is connecting electrical wirings and coolant hoses. The AEF engine used a different glow plug relay, but the original VW bus T3 glowplug relay can be used with some modification. I soldered two resistors of total 580ohm to the temp sensor wiring (at the waterflange at top of the engine, black/blue) this will trick the relay and let it glow a little all the time which is needed for the AEF to run clean/nice. The grey/green wire from the pump works like a electric choke at cold starts and can be connected to a timer relay for about 20sec. I bought a cheap timer relay from EBay that would probably work but it was so brittle and crappy. So I didn’t trust it, I just ran a wire to a switch on the dash, will work like a manual choke, almost like original but electrical rather than mechanical, bullet proof too.
Since the old CS intake and air filter box is installed on the little taller new engine, the wires in the engine compartment beside the airfilter needed to be moved upwards (around 60mm) to make space for the filterbox.
I found the diameter on the AEF water pump flange bigger than the old CS which made it impossible to re use the 90degree coolant hose. So I ordered a new 25mm 90degree coolant hose that will be jointed togheter with the old hose.
The crankcase breather need to be cut off in the end, and joined (with metal pipe insert) with the AEF hose. The connection at the cam cover is different on the AEF.
If any one need finished 587ohm resistor for the glowplug relay, let me know and I can ship some out. All you need to do then is cut the wire, crimp on spade connectors on both ends and plug in the resistor. That’s it! firstname.lastname@example.org
