If I could get my hands on a second one I could double stack them and forgo the standoff spacers. The only other one that I know of is 3 hours away in Oklahoma City OK. It was on the XC90 the engine and transmission came from. I may or may not still be there. I'm not inclined to do six hours of driving to find out.

Would OKC yard locate, remove and ship you the spacer?

Otherwise, make aluminum frame for spacer and air flow guide?

I doubt LKQ OKC would pick and ship. If they did most likely would cost as much or more then the used ones I found on eBay ~$70.00. I got the one I have out of LKQ Wichita for $15.00.

2007 - 2014 3.2L XC90s have the same frame. Volvo part number 30730523. There is a 2011 3.2L XC90 in Wichita that has one but the front end is all smashed in. It would be a miracle if it survived and I could retrieve it.

I would need to work out the dimensions and methods for fabricating one. I do not have sheet metal tools. It would need to be clamps, boards and rubber mallets for bending.

I have not installed the fan yet. It is just hanged by a couple of wire hangers.

Back side install would be the quickest and easy. I have all the hardware. If the motor cannot take the heat, the fan is only $26.00. Then I could try a front mount with all the additional steps.

Opinions? Insights?

Puller fans tend to be better/more efficient from what I've read, so you might want to stick with that setup. That just might be okay where it is. It looks a little close, but like you said worst case, it burns out from the heat and you can find another setup.

Offsetting the fan on the radiator gives about 2 " of clearance. Perhaps the best solution is 2 x 12" fans mounted catty-corner.

My tiny 1.8T VW engine has two cooling fans in two stages

That may be a really good idea. Miatas use the same setup of two fans.

Two 12" circles will fit in a 24" X 18" rectangle but before I order I'm going to sit down and figure out two 14" will fit.

Post by **RickHaleParker** » 04 Jul 2020, 22:50

14" will not fit. They would be about 10.8 " center to center when mounted catty-corner. They would overlap.
The heat exchanger on the radiator is 18" x 24" √ ((18 – (2 x 7)) + (24 – (2 x 7))) = 10.77 . The The hypotenuse of a right angle between the two center points.

Here is a wild one: Take a gang of computer fans and plastic weld them together into a matrix. They are thin enough to fit between the radiator and the condenser without any fabrication to the rest. ( Would not work. computer fans have a low air flow for a given surface area and a higher percentage of the surface area is blocked by the motor. )

Two 12" fans cover more surface area then one 16" fan. Combined air flow is the same as a 16".

Ordered two 12" for $40.00. That is what I am going to roll the dice with.

Rick, the new beetle fan is really compact , let me know if I can measure it if plan A devolves.

Try as you may, you just can’t get away....from mathematics.....!
