Dayco promotes replacement thermostat quality message

Modern engine cooling systems are now highly sophisticated and play a critical role in emission reduction. The systems also have to cope with higher flow rates, advanced turbocharger technology and autonomous heating and air conditioning.


Even stricter future emissions regulations will require engines to operate at 10% higher temperatures and increased pressure in order to fall within the limits. This means increased thermal management demand and a vital role for the humble thermostat.

First introduced in the 1920’s, thermostat technology changed little in 80 years, however, more recently there has been a dramatic increase in design sophistication. Today integrated thermostat housings and MAP thermostats that are controlled and activated via the vehicle’s ECU, make a vital contribution to power unit efficiency. This means that when it comes to replacement quality is vital.

Dayco, recommends that only original equipment quality products should be used, as inaccuracies of more than plus or minus two degrees centigrade will have a considerable effect on the level of emissions emitted.

Dayco has also provided some useful thermostat fitting information:

Some thermostats have a bleeder or ‘jiggle’ valve, which is located in the flange and is designed to stop an air-lock being trapped in the cooling system. These versions must be positioned with the bleeder valve on the high side of the housing to allow air to pass through it.

Reverse poppet or ‘bypass’ thermostats have two sealing surfaces in order to regulate the flow around the engine and the radiator and these must be distinguished from normal thermostats. The use of a regular version in a bypass system may cause the engine to operate lower or higher than its specified temperature and impair its efficiency.

When it comes to integrated housing and MAP controlled thermostats, the increasing complexity of these thermostats means OE quality is a must for replacement so that the thermostat operates within the VM’s strict performance parameters and can provide a longer service life, meaning better long term value.

Dayco offers an extensive range of thermostats that are of OE standard in their quality, safety, efficiency and durability.
