All Dayco Timing Belt Kits meet or exceed OEM specifications.

Replacing components with the timing kit with water pump guarantees durability and performance of the entire transmission system. The engine cooling system stabilises the engine operating temperature by limiting the rise above the expected limits. The coolant is circulated by the water pump, which must ensure the correct flow at each engine speed. Incorrect operation of the water pump can cause significant damage to the engine. For this reason it is extremely important that it is systematically checked. In many applications, the water pump is controlled by the timing belt. Therefore, its control and any replacement during maintenance to timing control system is extremely important.

Dayco Poly-V / Serpentine Belt Kits have been designed for the most popular applications, ensuring that the end user has all the parts needed to perform a ‘complete’ job.

Continuous research and consistent collaboration with all car manufacturers, has given Dayco the opportunity to create complete systems that meet all technical and application required by the market.

Many of today’s modern vehicles possess complex accessory drive systems that require the replacement of all worn components in order to operate properly. Dayco Demanding Drive Kits provide all of the required components to ensure a quiet, problem-free belt drive system. These kits have been designed to address the most demanding drives in the market.

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 successfully applied to chain kits.

In designing the chain kits, a “system” logic was followed, to ensure all the elements of the kit (chain, hydraulic tensioner, sprockets, guides) were included. Additionally, it is important all elements comply with the technical requirements of the single component. This guarantees maximum functionality, silence and a longer life of the transmission.

The Poly-V belts are produced for auxiliary transmissions of cars, commercial vehicles, heavy duty vehicles and buses. Service belts control almost all auxiliary systems. They have very important functions controlling the correct operation of

• The climate control compressor
• The power steering pump
• In some cases even the water pump
• The alternator

Designed as a value-priced aftermarket replacement option for 95% of the light vehicle population in Canada, both foreign and domestic.

Dayco Drive Rite^® belts are made with reinforced EPDM compounds for steady performance and reliability. They work well in a wide range of temperatures and load conditions and are an ideal option for more price conscious consumers. Offering smooth performance and designed to resist cracking, the belt is backed by a one-year warranty.

Ela belts, also known as “stretch” belts,  are specifically designed for 2 to 4 point drives that do not require tensioning. Although these belts may look like standard Poly-V / Poly-V Serpentine belts, they are very different. These specially designed belts have self-tensioning capabilities required by specific original equipment (OE) drives designed for a “stretch” belt. Vehicles that are manufactured with “stretch” belts must replace those belts with “stretch” belts. These belts are not interchangeable with standard constructed belts of the same size.

Specifically designed for applications that may have noise, vibration  or harshness issues, or in-drive systems in which tensioner take-up is minimal.

As the demand for higher output engines and tighter compartments increase, OEMs have elected to use serpentine belts with aramid tensile cord. The Dayco poly-V aramid serpentine belt has been engineered to maintain a quiet, vibration-free belt drive system. Unlike polyester-corded belts, the Dayco poly-V aramid serpentine belt will resist the expected elongations, especially during high accessory loading. This unique feature of length stability and minimal stretch can aid in difficult drives where span vibrations and tensioner movements are excessive. The Dayco poly-V aramid serpentine belt is built with Dayco’s specially designed EPDM rubber compounds to resist cracking and perform better under extreme temperature ranges.

Designed for specific OHC and DOHC applications ranging from normal service to high-performance, high temperature engines.

Manufactured with tough, wear-resistant fabric, high tensile strength cord and a molded tooth surface, Dayco’s timing belt provides consistent slip-proof power transfer and high resistance to oil and engine heat. The belt features a quieter, more economical molded cog design as well as a premium, high modulus glass fiber cord that delivers precise length stability to keep the engine running smoothly over the life of the belt.

Today, timing belts are subjected to new stresses and working conditions such as high direct injection pressure that in some applications exceeds 3,000 PSI, multi-valve motors with dual overhead camshafts with high loads, and turbocharged engines with high power and engine compartment temperatures above 250°F (120°C).

• HSN: This belt offers superior resistance to high working temperatures, even up to 230°F (110°C) and is designed to withstand pulsating loads.
• HK: Equipped with aramid-based fibers for superior durability and reduced noise, this belt style is manufactured for the latest small displacement high performance engine generations to withstand temperatures up to 250°F (120°C).

INDUSTRY-FIRST TECHNOLOGY READY FOR THE AFTERMARKET
Engineered for peak performance and reliability in today’s advanced automotive engines, the Dayco timing belt in oil (BIO) provides exceptional strength, improved durability and superior resistance to wear and tear in a challenging oil bath environment.

As the OE supplier and first to market, Dayco optimized its belt design by combining the best of both chain and oil technologies to significantly reduce noise levels during engine operation. By formulating a belt that works inside the engine like a chain, this Dayco invention enables OEMs to downsize the engine, decrease vehicle weight and create a quieter, smoother and more responsive ride.

V-belts have a trapezoidal section with edges cut and are highly performing. The V-belt is one of the many components that make up the transmission system of any car. The task of V-belts is to transmit the rotary motion of the crankshaft to auxiliary units such as:

• The alternator
• The A/C compressor
• The water pump

Dayco introduces its line of wheel bearing kits and brake discs, offering the market innovative solutions for the automotive sector.
All products undergo severe validation testing to ensure they meet Dayco and OE quality standards.

Dayco offers a wide range of car steering and suspension components that are considered indispensable. Steering and suspension need good maintenance to ensure optimum vehicle performance and safety while driving. There are over 3,300 codes to meet the needs of all car owners on the road.

Improper functioning of the water pump can cause engine damage, so it is important that it is checked systematically.

The engine cooling system stabilises the engine operating temperature by limiting the rise above the expected limits. The coolant is circulated by the water pump, guaranteeing the correct flow at each engine speed.

In many applications, the water pump is controlled by the timing belt. Therefore, its control and any replacement during maintenance to timing control system is extremely important.

The Dayco car electric water pump achieves the following:

• fuel economy
• emissions reduction
• engine efficiency improvement
• better control of energy consumption.

It is now an indispensable element in maintaining the optimal functioning of the cooling system.
The conventional water pump is driven by the belt: the higher the revs, the more water circulates in the system.
To manage the circulation, a thermostat closes or opens the system depending on the temperature.

Dayco car thermostat is a key component of the vehicle cooling system. It optimises the flow of coolant from the radiator when the engine is cold to reach the ideal temperature quickly.

Dayco radiator and expansion tank caps:

Quality at Your Service

The Dayco Radiator Cap range has been developed to complement our diverse cooling products range.

• Our new radiator and expansion tank caps range have been developed to comply with the strictest OE system
• Dayco radiator caps guarantee high performance having a significant role as a vital part of the vehicle cooling system
• Throughout the entire quality process, Dayco is constantly improving products and operations

The expansion tank is more complex as it is always under pressure, the pressure cap is located on this tank rather than the radiator itself. Typically the expansion tank is at the highest point in the cooling system with the coolant being continuously cycled through the tank, here the pressure released from the hot coolant fills the top half of the tank and acts as a force to push the coolant back into the system.

The overflow tank or recovery tank is used to recover the coolant that escapes the cooling system past the pressure cap due to rising pressure and temperature, in a properly operating cooling system, the coolant will then be siphoned back into the radiator as the temperature drops.

The purpose of the Heater Control Valve is to regulate the flow of coolant to the heater core. In the off position the heater valve blocks coolant flow to the heater core hence when no heating is required and the reverse when heating inside the vehicle is needed. The heater valve can be activated by vacuum control in late model vehicles and cable in earlier models.

Dayco spark plug cables are manufactured using the best technology available on the spare parts market and are compatible with the latest generation of engines.

Dayco’s experience in transmission systems has also resulted in another new product: Timing Chain.

Dayco’s long tradition and renowned expertise in the field of power transmission, together with our understanding of the importance of quality, testing and reliability, have led to the successful creation of a range of Timing Chains.

Improperly tensioned belts cause slippage, squealing, heat build-up and premature failure. Dayco engineers recommend careful belt tensioning. After a new belt has been installed, run the engine for 3 to 5 minutes to seat the belt. After seating the belt, reset the tension to amount recommended as per the vehicle manufacturers specifications.
