Dayco Standard Heater Hoses

Dayco standard heater hoses carry the heated coolant from the engine block to the heater core under the dashboard, and return it to the engine. They're made for general service on light trucks and passenger cars. The ultra-durable hoses are constructed using all EPDM compounds, with spiral reinforcement for high burst strength and heat resistance of -40 degrees F (-40 degrees C) to +257 degrees F (+125 degrees C). These black cover hoses are similar to the SAE 20R3, Class D-2, and are specifically designed to be compatible with all common coolants and coolant additives. However, they are not suitable for fuel or oil transfer. Dayco heater hoses are available in a variety of diameters and lengths.

Dayco Timing Chain Kits

Dayco's long tradition of toothed belt power transmission systems and its in-depth knowledge of functional requirements, as well as its know-how in terms of quality, testing and reliability, are also now successfully applied to chain kits. In designing the new Dayco timing chain kits, a system logic was followed to ensure that all of the elements required for replacement—that is: the chain, hydraulic tensioner, sprockets, and guides—are included with every kit. Additionally, Dayco has guaranteed that all elements of each timing chain kit comply with the technical requirements of every single component. This provides maximum functionality, silence in operation, and promotes longer transmission life. The kits are available for countless vehicles; order the replacement timing chain recommended for your application. Advantages of the Dayco timing chain kit range include: * Synergic design of each entire kit (chain, guides, tensioner, gears, and seals) * High robustness and proven reliability on test benches and in-vehicle fleet testing * High-strength steel, precision-machined tensioners to ensure reduced internal clearances for optimum control and management of the timing chain tension * High-strength plastic guides manufactured with glass fibers for additional strength * High-strength molding steel or sintered steel manufactured gears with specific heat treatments applied for the hardening of the toothed area surfaces
