Because of a long tour of Italy and the potential of high running temperatures I opted to uprate the existing fan with a high output 2 speed fan with its own thermostatic switch.

At the time I forgot about the otter switch, but now on looking I note that it has been disconnected.

Do I need to remove the switch as being a potential blockage to full flow?

The new fan worked perfectly and helped keep things cool despite an Autostrada accident causing a huge tail back M25 style.

Comment please

It didn't block flow when connected so the answer is no.

Agree. No need to remove as it just sits in the coolant in the header tank. J

Removing the otter switch would also lead to a rapid loss of coolant :D
