I have an older water temp gauge that looks like your product # 1837(chrome trim ring). The gauge I have has a god trim ring. I think the product # I have is 1538. What would be the product # for the 1538 water temp gauge?

Asked by: John De
Thank you for your question. They actually share the same part number P/N: 2258.

I've got these gauges, antique beige, for water, oil, tack, and rpm. I'd like to add a trans temp gauge but autometer doesn't offer one in antique beige. Will this water temp gauge work as a trans temp gauge. Fittings are alike & range is the same.

Asked by: Gusteve
Thank you for your inquiry. You can certainly monitor transmission temperature with a water temp gauge. They are identical except for the dial markings.

What sender unit do I need for this gauge? Does it come with the gauge? If not supplied could you point me to the exact sender unit on your website so I can buy one. I need to know the thread size as I need to tap my radiator to make it fit.

Thank you for your question. This gauge will come with our #2258 sending unit which has an 1/8" NPT thread.
