Technician Jonn has been looking at the cooling system of our 1956 Jensen 541.
He drained the system and removed various hoses to allow the system to be flushed with water. Once the flush had finished, Jonn ran a hose through the radiator. He opened the blocked drain and let everything drain away.
The heater matrix and head were flushed until the water ran clear before the engine was blown off. Jonn then checked the vacuum system to look for any signs of a loss of the vacuum. He then topped up the antifreeze and radiator and ran the car up to temperature.
