    I recently just joined and I know I might asking a lot already to try and find out what tubes these are. I'm looking to replace these because I'm not comfortable driving with my pipes looking like that and while I'm there I going to place any coolant line also just for the peace at mind.

    Yours look much worse than mine. I did spring a leak in one once at the very end of the longer hose and could not find a replacement so I cut it and was able to stretch it to fit. Good luck in your search.

    Probably could get something made. They don't look all that complicated. For cheap, I would probably use coolant junctions from another automotive application. There seems to be a lot out there.

    Hi:
    There are a couple of sites that are pretty good at guiding you toward obsolete part numbers, as long as you input the VIN, or the frame, and model number of the vehicle.
    The vehicle numbers were put in different places according to the year of manufacture.
    On the car you are describing, the numbers are posted on a sticker located on the rear side of the drivers door jamb.
    The VIN will have the 17 digit format JT3VN39W2S02XXXXX, and frame and model # will have a format similar to VZN130L-GKMGEH.
    The sites are www.PartSouq.com and www.Amayama.com.
    The sites seem to use the same microfiche that the dealers used back in the day.
    Good Luck.
    Art.

    Hey Frank,

    I've got an 87 that i pulled the 3.0L out of and did a bunch of research on the heater plumbing. Here's the info you're looking for looks like you have a rear heater in your rig:

    Also looks like someone has changed out a couple of the heater tubes already. Your best bet for the metal pieces is robbing them off another 3.0l. I do think the 3.4 have some that are very similar so you might be in luck there?

    Your best bet would definitely be going through Toyota parts. Shibrew's got the diagram from their site. They will be the perfect length and shape. A little pricey, but worth it to save the headache. If your heater hoses look like that, there's a few other coolant hoses that you'll wanna take a look at. I just replaced all of these on mine.
    -One at the back near heater hoses but towards the centerline of the car. It makes a nice U shape.
    -There's two on the underside of the throttle body, one coming in and one going out.
    -Down on the bottom of the engine on the driver side, there's two more. They go to the engine cooler. One that's a little U-bend that is a bitch to get at and another long on that goes to the thermostat housing.

    Too many for this space.
    Let me know if you don't find what you're looking for.
    I have a parts rig that has them.
