I had to have the new cylinder heads put on my engine. Since the new temperature sensor in the heads now measures the actual coolant temperature rather than the actual cylinder head temperature, and the max coolant temperature limit for the 50/50 water glycol mix is 120 degrees C, I am trying to determine if the following Cockpit VDO Temperature Gauge will be compatible with the temperature sensor that is in the new cylinder heads: VDO Temperature Gauge Part # 310-915 Temperature Range 120F-300F / 50C-150C Gauge requires VDO Ohm range of 10 to 180 Ohms 12 Volts The attached curve is the performance curve for the Rotax sensor in the new heads. I am not an electrical guru and am not sure the above stated gauge is compatible with the Rotax sensor and will indicate the correct coolant operating temperature. Is there anyone out there that has the new cylinder heads, and if so, what type gauge are you using to indicate the coolant temperature in the cylinder head? Is the above gauge the correct gauge for this application? Thanks for your help. Hugh G. McKay III, P.E. Fellow, L.M.
