Dayco Lower Radiator Hose 01-03 Ford SuperDuty 7.3L Powerstroke
Description
Overview
Dayco cooling system hoses feature knitted reinforcement, a synthetic EPDM rubber construction for high strength performance, protection against abrasion, and resistance to oil, mud, salt, road debris, ozone and coolants. They can also withstand temperature variations from -40°F (-40°C) to +257°F (+125°C). The inner base is reinforced with knitted rayon for maximum strength and burst resistance. In addition to meeting SAE J20R4, Class D-1 requirements, this hose also meets Type EC electro-chemical requirements as specified in SAE J1684, which prevents inner deterioration caused by the build-up of static electric charges.

How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
