TRIDON TT299-180

The TT299 engine thermostat opens at approximately 180°F (82°C) and controls the flow of coolant between the engine and the radiator. It helps the engine warm up quickly and then holds it at the correct operating temperature.

A wax-pellet element expands as the coolant heats up, opening the valve smoothly and progressively. A quality thermostat supports good fuel economy, cabin heating, emissions control and engine life by avoiding both overcooling and overheating.

Fitment

Confirm the part number and opening temperature against your vehicle's specification. Fit with a new gasket or seal, make sure the jiggle valve or air bleed is positioned as specified, and bleed the cooling system thoroughly after refilling. Signs of a faulty thermostat include overheating, a temperature gauge that stays low, poor heater output or fluctuating engine temperature.

Always follow the vehicle manufacturer's service schedule and fitting instructions, and have the work carried out by a qualified technician if you are not confident doing it yourself. Replacing the thermostat when the coolant is changed is a cost-effective way to protect the engine. Store spare parts in a cool, dry place in their original packaging until they are needed. Our team is happy to answer questions about specifications, compatibility or ordering in larger quantities for fleet and workshop use. Every part is checked against its part number before dispatch, so what arrives matches what you ordered. Use the coolant type recommended by the vehicle manufacturer when refilling. Stocked in New Zealand and dispatched quickly, so your vehicle spends less time off the road. Buying the correct part the first time saves on labour, avoids repeat jobs and gets the vehicle back to work sooner. Keeping a spare on the shelf is a sensible move for workshops, fleet operators and home mechanics who would rather not wait on parts. Pairing this part with a general inspection of the surrounding components is good practice, as related parts often wear at a similar rate. Regular maintenance with dependable replacement parts protects the value of your vehicle and helps it pass its next Warrant of Fitness or Certificate of Fitness inspection.
