L. Engine cooling radiators may be replaced with alternate parts subject to the following restrictions:
1. Radiator core dimensions (width, height, thickness) cannot be smaller than the standard part.
2. Radiator must mount to OE radiator mounts.
3. Fluid capacity and dry weight of the radiator must be no less than that of the standard part. Installation of an alternate radiator may serve no other purpose (e.g., to allow a cold air intake passage).
4. A replacement radiator may contain an integrated oil cooler provided the portion of the radiator that is utilized for coolant conforms to the remainer of 14.10.L.
5. Installation of an alternate radiator may serve no other purpose (e.g. to allow a cold air intake passage).
The mountune radiator is larger than stock, mounts to the stock location with stock hardware and holds about 2 quarts more fluid. I do not have the weight of the Mountune rad but I could weigh the OEM and give you measurements if you really want them. There are some good videos out there that show them side by side. I run SMF with it.
