Dayco Heater Hose | Heater Inlet | 01-04 GM 2500HD/3500 6.6L Duramax LB7
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

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.
