Something to consider next...the sports thermostat!
It seems that by reducing the valve temperature by about 10 to 15 degrees celcius compared with that of a standard thermostat, the TRD sports thermostat increases coolant circulation and reduces performance bottlenecks caused by engine heat, to bring out the best in engine performance. (Maintains valve temperature of 71 degrees celcius.)
Certainly seems like a good addition for short engine bay vehicles such as Toyota Wish as the heat build up is rather rapid. When the engine is cooler, the fan noise is reduced and the car is suppose to be more quiet too.
However, heard from Henry that it has to be used with a better radiator cap for it to work effectively..
Upping the valve opening pressure of the pressure regulator on the radiator cap to allow higher radiator pressure increases the boiling point of the coolant, reduces bubbles, improves cooling, and generally maximizes the cooling performance of the radiator. The increased valve opening pressure of the TRD radiator caps is at 127 kpa (1.3 kg/cm2) and 147 kpa (1.5 kg/cm2).
Going to check it out tomorrow when I have the chance.
Cheers,
