    Yamaha heater install in '19 X4

    So I am installing the OEM Yamaha heater in my X4 and noticed that the "T" to interface with the radiator hoses that are cut, the fitting just slides in without any resistance. The hose is probably 1/16" larger than the ID of the fitting, no resistance. The 5/8" hose supplied with the kit installs with what you would call a normal amount of resistance.

    So my question is for those who have installed the Yamaha kit, is the large existing radiator hose fit that poorly on your "T" as well?

    Also I notice on the dash vents that they installed the adapter onto the vent. You need to unscrew the adapter from the vent so it will fit through the 2.5" hole cut in the dash. The dash will sandwich between the vent and the vent adapter.

    Believe it or not, those T fittings will seal just fine. Just tighten them down.

    The newer kits have a different sized fitting that fits better. So if you really don't like it, contact Yamaha and see if they'll send you a pair of the new ones.

    Thanks for the reply. I just wanted to make sure they will work and they seemed to tighten down OK. Need to refill the cooling system so I can warm it up to pressurize the system and check for leaks. It is odd that they would not have a tight fit like the 5/8" dia. hose connection.
