So I ordered a complete set of coolant hose for my '93 fd a while ago from ray crowe and never got around to replacing the hoses. But now something else has happend to my car, and i'm going to end up taking alot of it apart anyway, so i decided while waiting on parts that it would be a good time to put the new hoses on. I started and i've replaced all but 6 of the 14 hoses. I do not know where these hoses are supposed to go and i was wondering if someone here on the forums could identify them and tell me where they go, or direct me to some sort of diagram that actually shows all 14 of the coolant hoses locations.

Most of the hoses i have left over are still in the bag with the part number, if thats of any help. i have an idea of what a couple of them might be but would like some sort of confirmation. I think the hose labeled 3 is the throttle body coolant line? and i think the hose labeled 2 might be the one that is directly behind the filler neck, underneath some of the rats nest plumbing?

as for the others, i dont really have much of a clue. If someone could help it would be appreciated. Thanks.

The parts fiche in the stickies has diagrams showing all hose locations.

 

Hmmm. You mean the one in the tech manual directory sticky, that goes to FD newbie imports and then through another link? Thank you for showing that to me, i didnt check that sticky out before. However, that PDF isnt working for me right now, it wont load for some reason. Says its something like 380 pages or something too. I'll try to get it to work tomorrow. If anyone knows of a more direct way to access that diagram that would be cool. I'll check back tomorrow.

If that can help a bit

N3A1-15-186A Upper radiator
N3A1-15-185A Lower radiator
N3A1-15-183A AST in
N3A1-15-184A AST out
N3A1-13-681 Throttle body in
N3A1-13-691 Throttle body out
N3A1-13-692A Throttle body out to water pump housing
N3A1-13-53X Turbocharger in
N3A1-13-54X Turbocharger out
FD01-61-211A Heater core in
FD01-61-214B Heater core in
FD01-61-212A Heater core out
FD01-61-213B Heater core out

 

As you take them off, find the hose that most closely matches it.

 

In the first pic the top shorter hose goes from under the throttle body to the coolant pipe below. The longer one is the lower turbo coolant hose.

Hose in 2nd pic goes behind the alternator.

Third pic looks like it may be the upper turbo coolant hose but can't tell as the label is covering most of it.

4th pic goes from the nipple on top of the rear iron to the backside of the throttle body.

5th pic are both to the heater core and go on the passenger side of the motor under the abs unit.

 

Ah, actually that does help a little bit. I did a random search and found this thread by damonb https://www.rx7club.com/showthread.p...e+coolant+hose and it's even a little more specific than that. I think that is all the information i will need to find the rest of the hoses.

well, I did that for the first 8, but i was unsure of a couple of the ones i had left, and i didn't even know where to find the rest of them. That engine bay is cram packed.

Thanks for being specific man. I don't think i'll have anymore trouble finding radiator hoses and now i have a nice reference all put together in this thread lol.


once again thanks guys.
