I converted my new blue top to grey top mode when I fitted it by blanking off the
two ports where the bi-pass hose would normally fit.
The original builder/owner of my plane did not fit the thermostat but instead installed
in-flight adjustable louvers on the starboard radiator, so that temperatures
can be adjusted by the pilot. I have retained this feature with the new
engine - it provides improved maximum cooling (no thermostat to reduce coolant
flow) and may also reduce the risk of cold seizure (radiators are always live
so there is no risk of a slug of ice cold water entering the engine from cold
rads if the thermostat were to open suddenly).
Whilst I was installing the new engine I also fitted coolant powered carb heaters,
and replaced the coolant overflow bottle with a car pressurized expansion
chamber. Since doing this my coolant system has remained totally free of any air
bubbles (25 hours).
