L6 Auto Meter Gauge adaptors for oil and water temp

Recommended Posts

I had tried searching and one of the references I found gave the incorrect autometer part # for the metric gauge adaptors for mechanical and electrical gauges for the L6 or at least  the block from a 28ZX Turbo. 


The thermostat housing has a temperature sensor fitting which is threaded for a M16 x 1.5. 

The mechanical gauge adaptor is autometer part # 2275 (5/8 - 18UNF to M16 x 1.5)

The same adaptor works for the oil temperature sensor in the sump on the ZX Turbo block if installing a mechanical gauge, a couple of fittings are also threaded the same, i have a cylinder head temp gauge installed at the rear of the cylinder head in the fitting used by the heater bypass.


For autometer electrical gauges use adaptor  autometer #2268

(1/8 NPT to M16 x 1.5 )


Hope this helps someone else,
