2005 Electra Glide Harley Oil Temp Gauge Install

Our 2005 Electra Glide is up on our mechanic Chris’ lift with a drain pan under the tranny and the seat removed. The battery ground cable has also been disconnected.

Swap out that air temperature gauge for a much more useful oil temperature gauge!

Using a 5/8” socket and 5/16 Allen, Chris removes the engine oil drain plug (right hole) and oil pan plug (left hole) from the engine oil pan under the tranny.

If you own a twin cam touring model with a fairing, you have the not-so-useful air temperature gauge that comes standard with the gauge package. But do you really need a gauge to tell you it’s 100 freakin’ degrees out? A much better use of that gauge spot is an oil temperature gauge. This setup gives you valuable info during your ride on how your engine is operating, especially on very hot days. This upgrade is not hard to install and can be easily done right in your own garage, not taking more than half a Saturday to complete. In fact, you should do it at the same time you’re changing the engine oil and filter, since you’ll be draining the oil anyway to install the kit’s temperature probe.

Here is the engine oil drain plug (bottom) with its magnetic tip to catch any ferrous metal slivers from the oil. The top must be removed to install the oil gauge sensor.

Since we’re going to install our kit onto a 2005 Electra Glide, we went with a black-face 2″ diameter oil temperature gauge (#70900283/$149.95), which is styled to match the original equipment gauges on our Electra Glide. This gauge kit, which is also available with a silver or titanium face gauge to match other models, fits 1999-2013 FLHT, FLHTC, FLHTCU, FLHX, FLTR, and Trike models. However, it doesn’t fit 2009 and later CVO models. The kit includes the gauge, wiring harness, and all needed hardware. Check out the accompanying photos and captions to see just what it takes to install this very useful gauge. AIM

Chris uses an 11/16” wrench to install the supplied oil gauge sensor/brass bushing into the oil pan. Tighten the bushing, not the sensor, until it’s snug in the pan. This as a tapered busing, so don’t kill it!

The new gauge goes into the inner fairing and into the gauge bracket just like the stock unit. Chris aligns the tab on the gauge with the notch in the fairing to properly position the gauge in the inner fairing.
