Arrow NEED HELP with Heater Core Coolant Hoses

had to tow my car back to the shop last night because some of my lines for the heater core busted. they were old and all crusty. now i need to get new hoses but i dont know where to start. all i could find is samco hoses or the like but for radiator hoses (upper, lower) or cheap ebay silicone hoses that come with everything but i dont know if i can trust it.

im thinking theres gotta be oem part numbers or samco part numbers that everyone uses to replace those hoses but cant seem to find it on zilvia or the web. i want to replace all of them. theres like a good 5-7 of them. still working on a couple that are hard to reach.

i need suggestions on what i could do right now. what are my options? thanks in advance.

its a SR S13 blacktop in a S14 zenki

here's some pics of the hoses that leaked out.

here some more pics...

these are the hoses i took off, they're all in pretty bad shape so i want to change them all out. i wanted to get a samco hose kit but they dont have one for the SR. alli found was cheap eBay knock offs.

then i found these, but i dont understand how i would use them.

MY two cents:

The hoses you removed are still coolant hoses but not necessarily heater hoses, you removed them from under the intake plenum.

The heater hoses just connect to the heater core in the fire wall and are the ones from the enjukuracing.com link.

I would just go to an auto parts store and buy the short hoses and replace those. And if you really need the "heater hoses" in the back, then I would buy those from the enjukuracing.com link.

im told that the diameter of the usdm and jdm pipes are different so that even after i replace the hoses with usdm sizes, they will eventually burst again.

Check page 16 post#237 on this thread https://www.s-chassis.com/forums/sho...=42547&page=16 I replaced those hoses with ones from the parts store, maybe the part numbers will be helpful to you.

sounds like someone told you wrong. there is no such thing as usdm or jdm diameters, it's metric or sae.
