Elan +2 Cooling Fan Assemby, Please Help!

PostPost by: tr8bofin » Sun May 25, 2014 3:50 pm

Greeting Faithful,

I'm attempting to reinstall the radiator and the electric fan assembly on my Plus 2 and can't seem to work out how it all goes back together. The radiator attaches to the support structure with 5 bolts per side; 2 each at the bottom and top and one in the center. The 3 holes per side in the fan motor mounting bracket can be attached in several different ways, aligning with three of the five holes on either side of the radiator. It seems no matter how I mount it, the fan blades interfere with the support tube for the hood/bonnet.

Assuming these are the correct components (see photo) there must be a way to put this together! A picture is worth a thousand words. If someone with the same componentry could offer a picture or any advice as to how this all works, I'd be most grateful.

Last question: I know the fan assembly mounts in the nose of the car, not between the rad and the engine. Assuming I can eventually work out how it mounts, should the fan be wired to "pull" or "push" air through the radiator?

The fan mounts to holes on the side of the radiator, I think there should pre drilled holes. I believe the longer arm should be on the left side when looking from the front.

The fan motor should be mounted with blades near the radiator and pushing air through the radiator.

Picture attached.

Personally I am changing this setup out for a Cliveyboy system currently as I think it will struggle with the Texas heat.

Awesome. Just what I needed. Upgrading to a more efficient fan set up is almost a must here in Texas. I was looking to simply get the current set up and working for the time being but I'm probably better off upgrading while I have things apart. THANKS!

I have just acquired & rebuilt the stronger fan motor for my Federal Sprint (same Radiator/ Motor / Brackets as the Plus2 130/5) so for the record here's what the assembly should look like:

I also revised the wiring to add a relay so the motor current is not carried through the radiator temperature switch. Here's the wiring diagram & a picture of the relay attached to the rear (engine side) radiator support plates:
