I installed the Oil Temp probe and Indicator in my C172 with no issues. System worked as advertised. Thank you.

OIL TEMP GAUGE 100-250 48" CAP

The first one I received read 190 degrees in boiling water, I returned it and in 24 hrs had one that tested 210. Close enough. Installed and works fine

The gauge is just what I needed and works well. I did see other reviews that encouraged doing a boil test to make sure the gauge is accurate. The first one failed and I returned, the second works great. I would also tell anyone using this gauge to test before installing.

Just what I wanted and worked perfict.

arrived quickly

This is the mfr of the same gauge for Scott and a direct replacement for many original/older Cessnas. If you want internal markings send it out to an instrument shop. You can also place markings on the glass directly yourself. May requre a new adapter nut to insure no leaks since the flange on the bulb changed over the years.

Excellent product, performed as expected

I would give you 6 stars if there would be a very simple range mark kit included, I would not estimate over $1.00 cost.

Exactly as advertised, great price and quick delivery.

The first gauge I received didnt work properly. When the probe was immersed in 212 degree boiling water it would only indicate 198 degrees. However, customer service was absolutely courteous and expedient in getting a replacement gauge out to me. It passed the boiling water test and is now installed in the airplane.

Like the more detailed markings. I did test it in boiling water before install and the highest temp reading it went to was only 205 though. Not perfect but pretty close.

Bought this as a replacement for the same model that failed after being in use about 10 years. New one working like a charm, and was easy to install. Lets see how long it lasts.

Exactly what I needed. Would have been 5 star if it had red line markings. This is one of two gauges ACS offers, dont buy the other one, I had problems with the bulb end sleeve. It wasnt crimped properly, it came loose and the line failed. The Rochester unit is more robust imho.

like normal for Aircraft Spruce, the right part, on time, and damage free. Only ding is I wish we could put a red line inside the glass.

The gauge when tested in boiling water was 10 degrees low.

Gauge seems to work fine, but the calibration is off. In rapidly boiling water, 3 other thermometers read 212 degrees F. This gauge reads 200 degrees F. Ive Red Lined it accordingly but somewhat disappointed.

I dont normally write reviews, but it thought Id share my experiance with the gauge. First tand foremost it is a quality item and I tested it to be accurate within about 5 degrees F. It nice because It is a single unit that does not require any electrical wiring (its a mechanical gauge). The problem is with the install. You have to turn the entire unit to screw it into the engine, being careful not the twist the cable from the gauge to the prob. If you do you will break it as it is made of copper and filled with fluid. This is problematic because you have to pass it though the firewall to do install it. Unless you want to drill a 2 1/4 inch hole in the firewall there is no practical way to do this. I tried being careful, but wound up breaking the cable on installation. I would recommend using an electrical gauge to avoid this problem.

Had to return the gauge for a replacement as it didnt indicate properly (see succeeding review after the exchange for a more detailed description.
