B16a Into a 1991 civic dx What rad hoses do i USE.. I can not find any thing on this anywhere.

 

Upper radiator hose-
92-93 Integra GSR, Acura part number 19501-PR3-000. Trim to fit.

Lower radiator hose-
90-91 Integra, Acura p/n # 19502-PR4-A00. Trim to fit.

 

I was reading a 1990- 1991 Integra will work For top and bottom Why do you say Different?

 

I have never actually compared the old and new integra hoses side by side. I am assuming that one hose works for the top but maybe not for the bottom. So by using a mix match set you set a perfect fit. You can read around and see what others have used. I have searched and found a few parts list containing the info i gave you. Let me know.
