Wondering where to get a throttle body to rear housing coolant hose for the 1987 RX7 turbo II. Atkins used to have some at this link https://www.atkinsrotary.com/store/C...18-13-681.html. Unfortunately they are all gone, what have you all done to replace this?

 

so you have some options.

1. is to update to the S5 Thermowax housing and hose. the S5 thermowax hose points a different direction (i want to say towards the rear) and uses a ? shaped hose that is way easier. the Hose is N370-13-681, housing is NLA...
2. you can buy some other hose and cut it, N350-13-680 has a part that would work, and N3A1-13-536 looks ok too, N3A1-13-691A might work too. i think my last FC i used a N350-13-680 and let it loop around, again much easier

 

i did option 2 mentioned above. Napa and autozone both sell hoses of the same diameter and bend, I just cut to length and good to go. I believe mine was made by continental.

 

I’ve bought the replacement hose listed for the car and engine from Napa.

 

Samco might have something with a similar shape that can be cut to length.
