Tridon Thermostats:


This post was made in response to an issue raised in Thread1 outlined under the links section: 
Hi All,My name is Mark and I am the Brand Manager for Tridon Australia, this blog has just been bought to my attention and some of the comments are of concern. I would like to reassure you that Tridon backs its thermostats 100%. Tridon has been supplying thermostats manufactured by Motorad in the Australian market for more than 25 years. Motorad has been manufacturing thermostats for both OE manufacturers such as Porsche, BMW, Mercedes, Audi, Ford, GM amongst others, and aftermarket suppliers through out the world for more than 50 years. Motorad was one of the first companies in the world to gain TS16949 quality accreditation.Each Tridon / Motorad thermostat is tested 3 times to SAE specifications, during the manufacturing process to ensure correct operation. Some general information relating Tridon thermostats;
• Research
 The Tridon thermostat program is comprehensively researched to ensure correct product selection.
• Temp range (Example is a 180°F / 82°C thermostat)
 180°F / 82°C, this relates to the crack point of the thermostat or when it begins to open, (SAE spec has a + / - 2.5°C tolerance on this temperature).
• Alternative temp ranges
 The Tridon range includes many thermostats with varying temperatures, it is important to select the thermostat style and correct temperature range to suit your vehicle application to ensure correct engine / thermostat operation.
 Correct applications can be found
• Fully open temperature
 Is approximately 12°C above the crack point (i.e. for a 180°F / 82°C this will be approx 94°C)
• Fully open position
 The maximum opening position of the thermostat will be ¼ the size of the thermostat orifice (i.e. if the orifice of the thermostat is 20mm then maximum opening will only be 5mm)
• Installation
 Ensure that the correct coolant mix is used and all air is removed from the cooling system after installation.
 The thermostat requires liquid around the bulb to ensure an even temperature rise so the thermostat can open smoothly and at the correct temperature. Air locks behind the thermostat may cause the thermostat to open at the incorrect temperature and or open and close quickly (shuddering).
• Radiator Cap
 Ensure that the radiator cap is in good working order and tested to recommended pressure rating. The radiator cap is an extremely important component in the cooling system, a faulty cap can cause overheating through the incorrect pressure rating and or loss of coolant.
 Correct applications can be found • Thermostat Testing
 The thermostat must be suspended freely by a thread through the orifice in cool water / coolant. The water / coolant must be heated gradually to simulate the vehicle operation. The thermostat the thermostat will fall from the thread once the opening temp has been achieved. See above for opening temp and max opening details.
 NOTE: The thermostat should be replaced if it fails to open at a temp greater than 6°C above or opens 3°C below the nominated opening temp.I trust the information detailed above is useful. If you have any further questions please do not hesitate to contact me at Kind regards,Mark.
