1989 Volvo 760 Heater Hoses

Mackay utilizes leading edge rubber technology and compounds, supported by in-house processes from rubber mixing to final product. This ensures hoses are made to the strict specifications required for the advanced motor vehicles of the 21st century. Mackay Heater Hose is manufactured from heat and ozone resistant EPDM meeting or exceeding Spec. SAE 20R3 Class D-1. Burst pressure (min) 250 PSI, Working pressure (max) 40PSI. In vehicles of today, a hose has to be designed to withstand the stresses of modern, more compact but powerful engines that run hotter and at a higher pressure. Other factors include smaller engine compartments with poor heat dissipation, aggressive coolant additives, and stray (electrochemical) current that may be conducting through the cooling system. In short, the smaller but more powerful engines of today work a lot harder than the larger engines that were standard before. More heat is generated, higher burst pressures are required in cooling system components, and hoses have to be made tougher to withstand these demands. Mackay’s research and development chemists have developed new rubber formulations and manufacturing processes that ensure Mackay hoses meet the greater wear and heat demands created by modern engines. Rubber compounds used in automotive hoses today are predominantly synthetic rubber formulation. All Mackay coolant hoses are made from EPDM compounds that are highly resistant to ozone attack. Hoses made from some other rubber compounds may be subject to ozone deterioration.

Product Features:

• Excellent resistance to high temperatures
• Resists chemical attack (oils, fuels etc.)
• Excellent Ozone resistance
• Good resistance to abrasion
• High resistance to vibration

Providing reliable service in applications requiring molded hoses, the Dayco heater hose is designed to replace OEM coolant hoses. Made with the same bends and routing as the original assembly, this molded hose is meant to fit the vehicle precisely. The knitted reinforcement and synthetic EPDM construction provide high-strength performance and resistance to detrimental environmental elements, coolants and temperature variations of -40°F (-40°C) to +257°F (+125°C) and the “quick connect” end allows for fast, convenient installation.

Product Features:

• Meets the requirements of SAE J20R3, Class D-1
• Designed to meet Type EC electro-chemical requirements as specified in SAE J1684, which prevents inner tube deterioration caused by the build-up of static electric charges
• Engineered as an OEM replacement
• Meets Type EC electro-chemical requirements as specified in SAE J1684

All APA/URO rubber coolant hoses are pre-shaped and double reinforced for extra strength and durability. Each hose is manufactured from ECD (Electro Chemical Degradation) resistant materials, which prevents electrolysis from breaking down the rubber from the inside out. All APA/URO cooling components are made to meet or exceed OE standards.

Product Features:

• All cooling-water hose inner linings are resistant to electrochemical cracking
• high strength and resistance to oil, mud, salt, road debris, and ozone
• Resistance to distilled water and water ethylene glycol mixtures
• Resistance to air temperatures of up to 125C

Premium hose constructed for long service life.

Product Features:

• Good resistance to high temperatures for extended periods of time, which prolongs service life
• Meets SAE 20R3 Standard Wall Class D-2 requirements
• Temperature Range: -40 Deg. F to +257 Deg. F (-40 Deg. C to +125 Deg. C)
• CAUTION: Do not use for fuel or oil transfer applications
• CAUTION: Do not use for fuel or oil transfer applications
• PLEASE NOTE: Item is priced and sold by the foot. See store for details.

Gates Vulco-Flex(R) II hose will bend in almost any direction. It easily replicates the angles and planes of a wide variety of expensive original equipment coolant hose, for quick, easy replacement.

Product Features:

• Improved sealing surface for greater leak resistance
• High flexibility for easy installation
• Maximum vehicle coverage with minimum inventory
• Resistant to heat, oil and ozone
• Rated for SAE 20R5 Class D-2 performance
• Temperature Range: up to +257 Deg. F (+125 Deg. C)
• Note: Gates recommends replacing clamps each time a new coolant hose is installed
• Caution: Do not use for fuel or oil transfer applications
