youngengineer Posted December 8, 2020 Share Posted December 8, 2020 (edited) Well after years of persistent leaking, my series 3 heater matrix finally gave up the ghost dumping litres of coolant into the passenger footwell. A simple bypass of the heater core was enough to get home and keep on going until now, however it's been getting unbearably cold.. I've been looking at several guides on retrofitting a defender heatercore assembly into a series 3, however it is not a plug and play solution requiring modification to the electrics/wings/bulkhead as well as actually sourcing a decent defender heatercore in the first place which seem to be either in terrible condition or expensive. I read something not long ago about the series 3 and defender heater matrix being of a similar if not identical size. Feeling adventurous and with defender heater matrixes as cheap as £26 on eBay, I thought I would experiment. As you can see from the first photo, they are not the same size at all! I wasn't about to return it regardless, heating had to be implemented by the end of the day. A few cuts here and there and and she was in.. Ok it's a bit of a bodge job but it's really cheap and easy and the heat output is significant.
