Nissan S13 200SX CA18DET
Twin Cam, 16 Valve, Turbo
Replacement Thermostat / Coolstat
Colder 71° Temperature
This great quality thermostat from Japanese Specialists Conceptua Tuning is perfect for your CA18DET Engined S13 200SX. Tired or broken thermostats can be a source of cooling problems, as it fulfils an essential vital role in controlling the flow from the engine to your radiator- even when fully open.
In fact the thermostat is one of the most overlooked parts of the cooling system! You already know that the radiator cap increases the pressure of the water in your cooling system to stop boiling under severe loads and after shutdown. But in fact the flow restriction caused by the thermostat (even when fully open!) causes the water pump to further pressurise the water inside the block and cylinder head- up to 30psi. This is vital in the cylinder head around the combustion chamber area where thermal loads are the greatest.
