Water Temperature Gauges

Water Temperature Gauges: Read Coolant Heat Before It Costs You an Engine

A coolant temperature gauge tells you exactly how hot your engine is running, in real numbers, instead of a dummy light that only flags trouble once it is already too late. You fit one to catch a failing thermostat, a weak water pump, a slipping fan or a clogged radiator while there is still time to shut down. On builds that run hard, a dedicated gauge earns its keep the first time it warns you before the boil. Our water temperature gauges cover mechanical and digital sender styles, plus oil-temp siblings that share the same install work.

What We Stock

There are 14 gauges in this category from 3 brands: AutoMeter leads the sample with 9 gauges, followed by Bikers Choice with 3 and Revel with 2. Current in-stock prices run from $60 to $163, which is a live range on what is on the shelf now, not a locked-in promise.

The AutoMeter side spans classic sweep dials like the Phantom II 52.4mm 100-250°F water temperature gauge at $139.15 and the mechanical Z Series 52mm transmission temperature gauge at $163.41. Revel brings 52mm digital OLED units such as the VLS 100-300°F water temperature gauge and its matching oil temperature gauge, both $160.92. Bikers Choice covers Harley oil-temp needs with the 04-up Sportster white-face dipstick gauge at $101.71 and the chrome oil tank gauge for 00-17 Softails at $61.71.

How To Choose

  • Mechanical vs digital. Mechanical gauges like the AutoMeter Z Series read via a capillary line and need no power for the needle. Revel's VLS OLED units are digital, self-lit and easy to read at a glance, but sit at the top of the price range.
  • Water vs oil temp. Most units here read coolant, but Revel and Bikers Choice offer oil-temp versions. Match the gauge to the fluid you actually want to monitor.
  • Dial style. AutoMeter's Phantom II and Z Series are 52mm sweep dials for a cluster or pod. The Bikers Choice pieces are motorcycle dipstick and tank-mount gauges, not dash gauges.

Fitment

Only 3 of these gauges carry model-specific fitment data, all for Harley-Davidson - Softail, Sportster and XL - across roughly 1982 to 2024. The AutoMeter and Revel dial gauges are universal-style and do not list vehicle fitment here, so confirm sender thread, line length and mounting size against your setup before ordering.

What Else You Need

A gauge is one part of a dash build. Pair it with Shift Knobs and Audio Systems if you are refreshing the whole cockpit, and check Quick Release Levers for cluster access. Browse the full Interior section for the rest.

Ordering

Every order ships with free shipping, and Affirm and Katapult financing is available. If you are unsure a gauge suits your build, call fitment help at 813-535-5801 or reach us through contact us.
