2013 Nissan Pulsar Thermostat — Purpose, Service and Replacement

Technical sources including the Nissan Pulsar B17/C12 factory service manual (Cooling System), the Nissan electronic parts catalogue, and major aftermarket catalogues (Dayco/Gates) confirm the 2013 Nissan Pulsar is fitted with a conventional, wax‑pellet engine coolant thermostat housed on the engine block. So yes — a thermostat is absolutely relevant and used on this model (MR18DE 1.8 petrol and MR16DDT 1.6 turbo variants).

The thermostat’s job is to get the engine up to its ideal operating temperature quickly, then keep it there. It stays shut while the engine warms up, helping with smoother running, better fuel economy, lower emissions, and quicker heater performance on chilly mornings. Once the coolant reaches the thermostat’s rated temperature (typically in the low‑to‑mid 80s °C range for many Nissans), it opens to let coolant circulate through the radiator and shed heat, preventing overheating. If it sticks open, the Pulsar can run too cool, chew more fuel, and throw a P0128 code
