    Re: Reworking 4wd radiator

    The female thread holes are not the same. The upper left one should be on the right. The hose could be snaked over there. Thats a full 'S' curve and might be ok. If you flip it, you would have to snake the bottom hose, like the mod in the thread above. You would also have to snake the 5/16" hose.

    Or the left port could be hole sawed out, moved to right side, below the smaller bung, welded. Old hole would need to be capped. Or plug left hole and weld new pipe, right side. You could do all the fit work and bring it to a shop to be welded.

    The radiator does come with a nice double fan shroud. I think I need to assume that the old plastic tin will not fit and fans will need to be installed with any aluminum radiator. I like the simple clutch fan system and consider that a downside of this aluminum radiator.

    I prefer the more generic mounting option on the Rywire radiator. It also does not have the fill neck like the Sirocco radiator. Both radiators would need to have the top hose snaked over or be modified. The Sirocco is Way cheaper. The Rywire is $475.
