WIN with Dayco
Published: 28 February, 2020
Dayco is giving each reader of Aftermarket the chance to win one of five brilliant backpacks. All you have to do is learn a little about thermostats, something Dayco knows a lot about, having recently introduced a range to its portfolio. The role of the thermostat is to effectively control the flow of coolant around the cooling system and allow the engine to reach its optimum working temperature as quickly as possible.
Modern cooling systems play a crucial part in the drive towards reducing fuel consumption and exhaust emissions. The demands for increased efficiency, together with factors such as higher flow rates, turbocharger technology, autonomous heating and air conditioning, have transformed the traditional process of engine cooling into complex cooling systems.
To win yourself a backpack, just answer the following question:
What is the role of a thermostat?
A) To reduce exhaust emissions
B) To cool the engine
C) To control the flow of coolant around the cooling system
Winner will be chosen at random from the correct answers when the competition closes on 20 March, and the winner will be notified by 25 March. The editor’s decision is final. No cash alternative offered.
- Dayco: OE damper pulleys
As well as producing engine products and drive systems, Dayco also manufactures OE torsional vibration dampers for a number of VMs worldwide. The company has now made the range available to the aftermarket.
“Modern powerplants are highly engineered to deliver the optimum combination of power and torque, alongside fuel efficiency and minimal exhaust emissions,” says Dayco’s National Sales Manager Steve Carolan. “This objective often comes at the cost of high levels of engine vibration, which is generally intensified by the significant pressures present in the engine’s combustion chambers, an occurrence especially prevalent with diesel units.
“This vibration is transmitted through the crankshaft and therefore has a significant impact on the engine’s power transmission drive systems.”
To reduce this problem, Dayco engineers have developed a range of damper pulleys, with the prefix DPV.
“Generally installed directly to the crankshaft, observes Steve, “the damper reduces the circular vibrations that cause the primary problem, decreasing wear on many of the engine’s components. Naturally, the front end auxiliary drive (FEAD) system is a principal beneficiary, which increases the durability of the entire powerplant, but they also improve comfort for the vehicle’s occupants.”
Three types
There are three types of damper that, depending on the application, are generally installed: The simple, double and decoupler.
“The simple damper is integrated within the FEAD system,” explains Steve. “Its single rubber element provides sufficient vibration reduction for applications with standard noise, vibration and harshness (NVH) requirements.
“The double damper encompasses two rubber elements within its metal parts, which are designed to absorb vibration at different frequencies, and is for use in applications that generate high power and increased vibration, such as modern diesel engines.
“Although the decoupler damper still incorporates a rubber ring, the damping function is carried out through metal springs, as opposed to solely relying on its rubber element. It is used on the latest generation engines with greater power and enables the FEAD system to cope with high mileage and adverse conditions, particularly for applications that feature belt start generator (BSG) function for their Stop/Start systems.”
Damper Replacement
Commenting on replacement, Steve says: “Dampers should be checked for signs of wear, such as abnormal noises, unpleasant vibrations or even steering oscillations, at every 40,000 mile interval or when replacing the auxiliary belt. However, as a matter of course and irrespective of the signs, Dayco suggests they are changed every time the timing belt is renewed.”
“In order to check the damper correctly, it needs to be removed from the engine because the back, as well as the front needs to be examined to fully assess its condition. In addition, whether it needs to be replaced or not, if its fixing bolts are designed to stretch on initial fitment, these must be changed, as they will no longer meet their design tolerances if reused.”
Steve adds: “Dayco DPVs are produced in the same facilities, to identical standards, whether the damper is destined for OE or aftermarket. Each damper in the range that also requires its bolts to be replaced, comes complete with the correct specification bolts.”

- Borg Automotive
BORG Automotive supply a very wide range of remanufactured automotive parts, offering extensive car parc coverage. The company has more than 12,000 part numbers across eight different product groups in its range – including both popular and rare units. The reman products are individually tested to ensure a uniform high-quality level. The company says its many years of experience means it can deploy in-depth reverse engineering skills in order to improve on weaknesses identified in OE parts. Choosing remanufactured components from BORG Automotive also saves up to 79 % energy consumption compared to a new OE or copy unit.

- Textar: New to range expanding locks
Textar has widened its aftermarket product range via the new addition of expanding locks, intended to ensure reliable handbrake function. Damage to expanding locks is common in certain drum brake designs as the condition of the handbrake can only be determined when the brake discs are removed. Most manufacturers recommend replacing expanding locks every four years. Textar, which is manufactured by TMD Friction, covers 99.9% of the UK car parc and includes pads, discs, accessories and brake fluid.

- New can for TOTAL and ELF
Total Lubrifiants, the company that sells TOTAL lubricants has introduced a new can for its entire range of TOTAL and ELF lubricants. The can features new colours, new labels and a more ergonomic design. It is also lighter, and the reduction in weight will prevent the emission of 9,500 tons of CO2 equivalent each year owing to raw materials savings. Products are identifiable on the new cans via colour coding: Platinum for top-tier, Silver for mid-tier and Bronze for entry range products. Labels have also been redesigned to be clearer and easier to read.
