ETC (CTS). Socket size.

Anyone know the socket or wrench size to remove the ETC engine coolant sensor. Mine needs replacing and not much room to get a tool in there.
It’s an 1986 5.0

When you are at the parts store, use the new one to size up a deep well socket or combo wrench.They should stock everything you need.If you online purchase your sensor, take it with you to a parts store.
