C19 0 Posted October 13, 2014 Hi, Im doing a 4L swap into my XE and for the cooling system I dont know where to go with it. I have an AU engine and a XG radiator. I dont know what todo for a recovery/expansion tank. I have the out lets on the thermostat housing and the top of the radiator. Anyone got an idea?

XESP351 211 Posted October 13, 2014 Check my build thread, will answer your questions but basically you have the outlets on the XE radiator swapped over for AU ones and run the normal XE recovery bottle. Use FG Thermostat housing and AU top hose with universal bottom hose. Share this post Link to post Share on other sites
