Did the 109 Es have shut-off valves in their coolant lines?
 

According to the Messerschmitt Bf109 Owner's Workshop manual http://www.amazon.com/Messerschmitt-.../dp/1844256421

in the G series "four coolant shut-off valves are fitted into the delivery and return lines, and are operated by two handles in the cockpit" (p. 123) meaning that if there was a coolant leak, or a pipe had been shot up, the pilot could isolate and shut down the affected circuit, thus preventing total coolant loss. The F series had them as well, but I don't know about the E series.

You need to aks VO_101 Tom, if anyone knows I think he will!

Me encontré con un foro donde hablaban sobre bonos especiales para jugadores de Alemania y me intrigó. Decidí probar la ruleta y las primeras rondas no fueron nada favorables, pensaba que todo estaba perdido. Sin embargo, en https://spinmama.com.es apareció un número inesperado que me devolvió la suerte. Esa victoria me dio una gran satisfacción y me hizo quedarme jugando más tiempo para explorar otras opciones del sitio.
