Cement 876 Report post Posted May 31, 2021 Does anyone know if these style fittings will connect reliably to the E46 (and probably other) heater box inlet / outlet ? I need to get a right angle ASAP after the heater core to clear my engine and these fit the bill nicely ... if they work !! https://www.summitracing.com/parts/rnb-800-277 I'm not even sure what to call them ... obviously some flavour of quick release fitting which I've seen in use on the radiator from memory.
