Our flying club's RV-12iS with a 912iS engine recently got a coolant radiator leak in an unrepairable area between the fins of the radiator which has grounded one of our two airplanes. A replacement is on order but is backordered until late December, early January and I wanted to reach out to the group and see if there are any builders out there with their engine on hand but still a couple months away from needing to run it that might be willing to swap their radiator for the one we have on order to allow us to continue flying into the holiday season. We are located in southern California. Any help anyone could provide would result in many happy pilots currently unable to fly our Vans airplane.
