" Thermostats are at the top o

" Thermostats are at the top of each cylinder head and have plastic covers that can be removed by unscrewing them with a 13/16" socket. Be carefull, there is a spring under there. The thermostats have very small holes in their casings. These holes love to clog up with silt and sand. Hold the thermostats open with some needle-nose vice-grips and blow some compressed air through them. I usually run the motor for a few seconds with the thermostats and covers removed in order to clear out any obstructions in the thermostat housings. Good luck. "
