QUESTIONS:

Does the sensor have to be in the coolant stream to read correctly? Can the sensor just be threaded into a 1/8 npt dry blind hole in the aluminum head? If a dry blind hole is fine does the end of the sensor need to be touching the bottom of the hole?

Asked by: Arccengineering
Thank you for your question. The sensor needs to be in a water jacket in order to read the temp correctly. If you are using a dry port then it is only going off the air temp hitting the probe. This will need to be installed into a port that constantly has water flow.

I purchased one off your cylinder head temp gauges. Can I purchase another thermasister  and switch back and forth between heads

Asked by: BaldEagle
Thank you for your question. Yes, the extra sender is model 2259. A switch can be used to switch between senders. The switch type would be single pole, double throw, and it’s critical that it’s a zero resistance switch.

Asked by: spiro
Thank you for your question. You will have to drill and tap the head for the sensor. The sensor is 1/8" NPT.

This uses a thermistor style sender instead of a thermocouple.  Does it mean that I need to drill and tap a hole in the head to mount the thermistor?  I have a 1972 VW Super Beetle for street and rally cross.

Asked by: RoarieVW
Thank you for your question. Yes, the cylinder head must be drilled and tapped for 1⁄8" NPT hole. Be sure not to drill all the way through.

Can this meter be used with a ring type temperature sensor that is mounted under a spark plug? The thermocouple would either b J Type or K Type. I can get both. Thanks for your help.

Asked by: Fastbug
Thank you for the question. While we do offer data acquisition systems and dashes that can utilize this style spark plug probe, we do not offer a gauge that is compatible. Our current Cylinder Head Temp gauges use this thermistor style sender as opposed to the thermocouple style of the spark plug probe: https://www.autometer.com/shallow-depth-electric-temperature-sender-250-300-and-340-deg.html

Can this cyl. head temp. gauge 3336 be used on a garden tractor that does not have a battery or other electrical system? Thanks

Asked by: Allen
Hi Allen, thank you so much for contacting us. Unfortunately, this gauge (and all of our head temp gauges) requires either a 12v or 16v, negative ground electrical system to function. Sorry for the bad news.
