Attention Volvo Penta AQ170-B30 engines, 6 cylinder in-line, 3 litres
I bought this temperature sensor because I designed the entire dashboard with new instruments. The connection on my B30 is a 58"18UNF. I chose a suitable sensor from SVB. Delivery was done within 48 hours. I unpacked the sensor and wanted to screw it in. It doesn't fit. Sensor too long and too thick below the thread.
What to do?
I looked in my almost inexhaustible collection of screws and fittings for a suitable thread extension and found one. But here too the problem, the through hole was too small. So I put the part on the pillar drill and drilled the hole to 11mm. The sensor is 10.5mm. Now seal both threads with Teflon tape and screw it in.
Works.
