Dayco, a leading supplier of engine components and drive systems for the auto industry and the after-sales service market, represents a new product line — thermostats manufactured in full compliance with the specifications of manufacturers of original equipment (OEM). The product range is focused on customer needs from Europe, Africa and the Middle East and includes a complete set of components — from thermostatic valves and flanges (hydraulic connections) to thermostats assembled with housings and sensors.

Thermostats ensure efficient flow control of the coolant, accelerate the engine heating and support the necessary thermal mode of its operation. Completing DAYCO are designed for engines of all types and meet the main requirements of the automotive industry.


Modern cooling systems are crucial to reduce fuel consumption. All the more stringent requirements for motor efficiency, along with such factors as higher flow rates, turbocharging technology, autonomous heating and air conditioning, led to the transformation of traditional cooling processes and the appearance of more complex integrated systems.

Reducing harmful emissions

In the future, environmental standards will require an increase in engine operating temperature by 10% to ensure optimal fuel combustion. This trend will require the creation of more powerful cooling systems with which the car will be able to effectively work throughout the entire life.

Reducing wear


Effective thermal regulation is one of the most important factors in the fight against premature engine wear.

Technological know-how DAYCO, high-quality materials and precision assembly of thermostats guarantee their safety, efficiency and durability at the level of original components.

Traditional thermostats

Traditional thermostats (thermostatic valves and inserts) represent a design of several main elements: a rolling stock, the main plate, the main and auxiliary springs, capsules with wax, flange and frame. The main plate of DAYCO thermostats is made of a solid fragment of steel, which makes it reliable and durable. The unique valve technology prevents thermal shock by protecting the entire cooling system. The thermoelement capsule is manufactured from innovative wax compounds with aluminum or copper and provides the most accurate activation temperature.

Cabinet thermostats

The quality of DAYCO body thermostats made from polyamide resins or aluminum is equivalent to original, which guarantees their high resistance to heating, water and mechanical loads.

The body of polyamide is carefully checked in the production process to achieve the perfect fit and the complete absence of leaks. The accuracy of geometric and overall design parameters provides impeccable pairing with hydraulic and other components of the cooling system.

Electronic sensors built into thermostats guarantee high accuracy of refrigerant temperature measurement with a response time corresponding to OEM requirements. Valves with an electronic sensory element directly related to the car computer, provide smart thermostat control aimed at reducing fuel consumption, reducing harmful emissions and improve the characteristics of the engine.

Guarantee reliability

Currently, the range of DAYCO thermostats includes over 250 positions, the quality and reliability of which is tested during the production process. New branded packaging emphasizes the manufacturability of products. Branded catalogs will help you quickly choose components for specific applications.
