I have a coolant hose leak. it is the hose that comes off the throttle body just under the air intake, it goes right then curves around and goes up beside the the plenum and then down and hooks onto the block right beside where the thermostat is. Ive looked at all parts threads and fsm stickies but cant find this hose. any help would be great.

Thanks, Justin

1988 4runner, Automatic since i didnt say that above
Cirlce 1 in the pic is the top of the hose where it goes in beside the thermostat
Circle 2 is where it comes out from under the throttle body



Oh and this is EWAYota's nice motor, not mine.

Their for the idle-air control valve used to adjust the idle of the truck when it's cold and warmed up. I just replaced mine when I did my intake work. I don't think you can get them preformed from a regular parts store; maybe the stealership, but other than that you pretty much have to make you own hoses out of some coolant line you can pick up at any auto parts store; 7/16 size if I'm not mistaken, and I used tranny cooler line and it works perfect; 3 feet should be more than enough, it's easier to cut extra off than it is to add more, if ya know what I mean.

There's one under the intake that you can pick up pre-formed, but it's called the by-pass hose and is not what your talking about (just so you don't confuse it with that, because that's probably what the auto parts store would think you're talking about, lol)

Hope that helps out.

Hey justinvd, Try this...Gates coolant hose #18010 and bypass hose #18400. I changed out all my hoses awhile back so I don't remember but I think your looking for part # 16264-35030, this is from the toyota dealership. Parts stores won't have this one. It's preformed and you can't bend a hose to match, you will create kinks. The gates hoses are further below the throttle body and intake manifold, you can get those at any parts store that sells gates brand. You should change these out too.

I just got out form under the hood of my 88 and looking at your motor I am just speechless and shocked Good looking motor, well from the top anyways Good luck on your quest.

The motor belongs to EWAYota, hes another guy on thie forum.

And thanks for all your help everyone, i went to the stealership and got the preformed one, they couldnt even tell which one it was from their diagram, they went to and from my 4runner like 4 times. I didnt feel like cutting any hose even though it woulda been easy, haha im going to school right now and i already hate doing repairs on the side of the road (building rules are we arnt aloud to work on vehicles in the parkinglot) so i just made it as easy as possible

Thanks everyone, Justin

Why does this motor have all of the TB vacuum ports plugged? Don't you need vacuum for your power steering and emission canister?
