Bosch SP0F000053 Style Line 2″ Mechanical Water/Oil Temperature Gauge (Black Dial Face, Black Bezel)
$ 9.71
- I installed under the hood so I can monitor temp while I am tuning/wrenching a live engine. I added an oil psi gauge under the hood as well. Not only do I like to see vitals without poking my head in the drivers window, but I also don’t trust the 18yr old gauges in my car. The factory oil gauge (2004 Grand Cherokee 4.7) is a “false” gauge, as the sending unit only has one wire. That means the gauge will only read 55psi, or zero. It is a glorified idiot light.Install of the temp gauge was a piece of cake, took 15min. I dropped the probe in the air bleed port, and mounted the gauge to the side of my CAI box. I did NOT install the gauge lamp, but I might in the future. It appears to be accurate, as I can see the gauge drop right at the temp my thermostat opens. And, shhhhhhhocking…. It tattles on what I always though was a liar, the factory gauge. Factory gauge reads cold by 12 degrees….
