Temperature sensors

The oil temp, water temp and electric fan sensor all use a 1/2" NPT size hole and the engine had none that size so I bought the right drill bit and tap to make my own. Here I am tapping the bung I am using for the oil temperature gauge



There was a nice thick area on the drivers side of the engine, close to the thermostat housing, where I could drill and tap a hole for the electric fan sensor




There was already a hole on the passenger side but it was too small, so it got drilled out and tapped for the coolant temperature sensor




I had to remove the oil pan to weld a bung for the oil temperature and was pleasantly suprised how nicely baffled the pan was




And here is a shot of the pickup, notice all the baffles to keep oil where it's supposed to be.




Here is the bung before welding




And installed on the car
