A medium deep 24 mm thin wall socket 3/8 drive and a short breaker bar, not ratchet. I also remove the water pump pulley.

Subject: Oil Pressure Switch Removal

The switch by the crankshaft pulley.

How does one R&R that switch without making it a major repair job. Can't
get at it from underneath - the oil cooler is in the way. From the top side
by removing the water pump pulley I can get a 15/16th socket on it,  but
there isn't enough room to get a rachet or pull handle on the socket.

Just wondering how best to approach this.

Any input would be appreciated.

John
