BA radiator Fit in an FG xr6

I do not know what any of those numbers mean, but there are two ways to find your answer. One is to visit any salvage yard and ask them to do a cross reference. They will have a large, very expensive "Hollander" guide. That lists every part for every car model and year with a code number. You look that code number up in the back of the book and it will list every application that part fits.

You can also look up the part for each car model on an auto parts store's web site. If the part numbers are the same, it will interchange between those models. If the numbers are different, you will not know why. The parts might be the same but have different part numbers because one has different mounting brackets, a hose inlet or outlet might be in a different spot, and things like that.

Many of the web sites will include dimensions and photos in their descriptions. You also need to look at the number of "cores". That refers to the number of sets of cooling tubes, from front to rear. Small engines may have radiators with just one core. Two cores is common too. Large engines may have a three-core radiator. You need to match the number of cores to what you have now to insure the radiator has sufficient cooling capacity.
