TempesT 43 Posted March 14, 2022 Hi team, XG ute had a woopsie on the weekend. Had a major failure of the heater core on the weekend that dumped the coolant. Had to leave the car 2 hours away and continue on my way. Heading over on the weekend and atempt to bypass the heater core by joining the inlet/outlet pipe work. Anyone know the internal diameter of the inlet/outlet heater core coolant pipes? Intent it to throw a joining barb on the pipe. cheers lads. Share this post Link to post Share on other sites
