Hi,

As far as the vehicle, is this a diesel? I'm showing nothing for a diesel in this vehicle. It could be because of location. Are you in the US?

Also, the 2.0L turbo is a gas engine here. Let me know if that is what you have. If it is, temperature information is based on resistance in the sensor. The idea of setting a max alarming temperature isn't possible unless you were to reprogram the powertrain control module.

Let me know.

Joe

Thanks Joe, the vehicle is a 2 ltr turbo diesel in Australia. The unit I have installed is called engineguard, it has 2 sensors, one attached to head, one on the gear box, readout on dash. My question basically is how hot can the head get before any damage occurs?

Hi,

I wouldn't want to get much higher than 230 degrees F (110 Celsius). Is that something you can set?

Let me know.

Yes, thanks very much, this is a great service. You might like to google Engine guard, an Australian product that I had installed on a previous vehicle and saved it from cooking an engine when a cooling fan failed. Thanks again Regards, Neal.
