    I've been having issues with my 06' Tundra overheating on me for the last several days. I had a feeling regarding the battery terminal connection and the power fluctuation while driving. I swapped the connection out and no more misfiring. The vehicle was idling just fine and bang I blew a hose assembly coming off of the drivers side of the radiator. I cant find an exact diagram for the lines coming off of the radiator. Please, if anyone can tell me which lines run from the side of the rad so I can replace the one i'm down, and also if the issue reoccurring is probable. Any wisdom is welcome thank you.​

    On a Gen1, there are limited number of hoses connected to the radiator: the large diameter upper and lower hoses to the engine, the overflow hose on the radiator cap neck, and the two automatic transmission cooling lines which connect to the lower tank. It sounds like you're describing the overflow hose from the radiator cap neck to the overflow reservoir.

    When the engine overheats, the pressure in the system exceeds the spring pressure setting of the radiator cap and that allows overheated coolant to escape into the overflow reservoir. Sounds like yours coincidentally blew off just as you had the hood up. Toyota does not sell that part anymore, but hose is available at any auto supply store.

    You still have a overheating problem. That is the real problem, not the missing hose.

    This could go a number of ways. Agree with JohnLakeman...you have an overheat problem.

    I'd start simple...fix the hose. Water pump leaking? Has the thermostat ever been replaced? If not, it might be time to swap it out. Its cheap and easy.

    Inspect the radiator core (if you can see it) and if it is full of corrosion, it might be time to replace. This won't be cheap or easy, but they all are subject to corrosion over time.

    How many miles?
