I know I have a coolant leak and was hoping someone could help me find out what hose I need to buy as I'd rather not buy a whole kit. All I can find on google is people telling me when to replace my coolant hoses. I did a pressure test and found the one I need.
Picture 1: This is the hose I need (highlighted in yellow). It goes into the firewall. Can I buy just any hose, or is it a specific Toyota part?
Picture 2: Different angle and while we're here; anyone know what the blue one is? Should I replace the metal part that connects the two?
Any help is appreciated! I am pretty new to working on cars by myself. I'm also new to this site and don't really know my way around the search function so sorry if this is a repeat post.
I believe that you could maybe use a chunk of heater hose from an auto parts store for the yellow one, maybe, but the blue one, I'm pretty sure, you'll need the preformed from Toyota. I might be wrong on both, but you can at least try the heater hose solution for the yellow one. The trick is to be sure it doesn't kink around corners. If you try to use a heater hose from a store, get plenty, as you may need to use a large radius around the corners to prevent kinks.
If you can't keep it from kinking on the corners, you're gonna need the preformed hoses from Toyota.
Just so you know, the yellow one only goes as far as the firewall. It connects to a feed-through there. So you only need enough hose to go from the metal pipe to the firewall. Once again, though, you can't permit it to kink in the corners.
Also, there are several small hoses under the throttle body that are preformed too. There are a couple of them you can get away with a piece of generic hose, but they're small hoses, some going around tight corners. You really do need the preformed hoses from Toyota for them. Check them if you ever pull the throttle body. They are 30 some years old, too, remember. Make sure any you pull you clean the metal hose barbs they fit onto. They're most likely pretty rusty by now. Mine sure were.
Better to check them when you can, than to blow one on the freeway half-way home on a freezing cold night. And that's when they'll fail on you, bet on it. Murphy Rules!
Get these. Already formed. Don’t have to track all the Toyota numbers down. One or two are discontinued anyways. I got my set for 40 bucks. If you don’t care care about the color. Amazon has deals. I wanted red heater hoses but black was 40 bucks. Heater hoses. Hope that helps.
