1993 Honda Accord Heater core hoses

I did some research and could not find an answer to your question. I have a suggestion on how to find out. Just measure the outside diameter (OD) of the pipes coming from the heater core. I would suggest that you use a dial caliper to do this, a tape measure might be difficult to see if placement of the heater core is not ideal. All hoses are measured from the inside diameter (ID). Order the hose size and length you need and replace with new hose clamps. Please be sure to order the right type of hose that can handle the high heat and high pressure. Should be an easy fix. Good luck!
