Double coil spring Design - Installs and works Perfectly
This thermostat features a dual coil spring design, and is currently working great in my 1997 Toyota Corolla.
Optimum running temperature is achieved more quickly during warm-up, and the continuous temperature during all modes of operation is optimal and very stable. If you need a thermostat for a Geo Prizm, a Toyota Corolla(and compatible makes/models with 4 cylinder engine) this one fits and functions perfectly.
