Hi Pam, I'm pleased to assist you. No, these will not fit heater core hoses. Heater core hoses require a specific type of O-ring that is designed to withstand the high temperatures and pressures of the coolant system. The O-rings in the Dorman set are not made for these conditions and could fail, leading to a coolant leak. I suggest calling our parts specialists at 1-866-529-0412 to provide the vehicle information so we can help you look for the right part. Have a nice day.

Hi John, thank you for reaching out. We are unable to answer your question accurately due to a lack of information. Kindly call our parts team at 1-866-529-0412 and tell us more about your vehicle.

Hi Alberto, thank you for reaching out. We cannot guarantee that this universal item matches the power steering pump of your 2002 Honda Accord EX. The inside diameter of the O-rings is 1/8 - 3/4. The outside diameters are 1/4 - 15/16 and the thickness are 1/16 - 1/9. We suggest you get a direct fit seal and O-rings instead from the local auto parts store or dealership. Have a nice day.
