    Suicide Hose 16267-43010

    I had one pop recently and figured this would be good info to come up on a SEARCH.

    Invoice description is HOSE, WATER, often called Coolant Bypass Hose.
    It runs from under the thermostat housing to under the intake manifold, right along the engine. There is a clip for it back about 6 inches behind the thermostat housing and really pain in the ass clamps on each end. You have to unscrew them loose, then they become a 'spring loaded' clamp you have to move over each nipple...

    When my stock 23 year old hose blew, toyota red dripped on the floor directly under the 'EFI' if you were looking straignt down on the intake manifold.



    List is $25.92.

    Well, what I think is going on is it's one of those parts designed in there so it blows, you loose your coolant, you can't pull over, you blow the headgasket, and the car gets totalled becasue dealer repair is $1500+.

    Amazing that that hose lasts for so long for sure. Says a lot for Toyota parts.

    This Suicide hose is just one of seven hoses that carry coolant.
    A week later, one of the ones that goes to the heater valve closest to the engine blew on me as well, so the tip is you need to replace all of them if one goes.
    Les in NM (hot) says he replaces the hoses just about every year to preserve his beautiful 7mgte. In the heat down there, the 'soft' rubber hose gets hard in just six months.

    I replace all my coolant hoses (including those going to the heater core) every time I do a timing belt. Cheap insurance and really easy to do.

    This is one hose we should try to find a perminent replacement for.

    well one reason that this particular hose goes bad is when your valve covers/cam towers leak oil on them, the rubber hoses will last 3 times as long if you don't have any oil residue ruining the compound.

    ...i've just run a standard piece of hose between the two ends. it's not like there's a complicated bend or anything.

    I used a standard hose from Carquest #19098 for mine last year. Had to cut it down to size, but it had a comparable bend. I had the intake off at the time so it was MUCH easier.

    I think the only heater hoses on a 5m I havn't been able to replace with just standard unbent heater hose is the upper and lower rad ones (for obvious reasons). I replace every single heater hose on any mk2 I get as soon as possible. Once you've had the joy of replacing a suicide hose on a 40 degree celcius day in direct sunlight on a mountain pass highway in the middle of nowhere you'll do the same.

    This hose under the intake is easy to change from under the car, once the car is lifted and the lower engine cover is removed. It would be somewhat difficult on the side of the road.
