ISR Performance Universal Coolant Temp Adapter - 34mm

The ISR Performance Universal Coolant Temp Adapter is an inline radiator hose adapter for installing aftermarket coolant temperature sensors. Fits 34mm (1 3/8 inch) diameter radiator hoses and accepts any sensor with a 1/8 inch NPT thread, which is the most common thread spec for aftermarket gauge senders. Includes a grounding bolt hole for sensors that require it.

What It Does

If you're adding an aftermarket coolant temperature gauge (Defi, AEM, Prosport, AutoMeter, etc.) and the factory location isn't viable or accessible, an inline hose adapter is the cleanest install path. The ISR adapter sits in the upper or lower radiator hose, sealed by two hose clamps, and gives you a 1/8 inch NPT port to thread your sensor into. An M4 x 0.7 grounding bolt hole is built in for sensors that need a chassis ground.

Sensor Compatibility

1/8 inch NPT is the standard thread for the vast majority of aftermarket coolant temperature sensors. If your sensor uses a different thread (M10, M12, etc.), this adapter won't fit without a thread adapter.

Hose Size

34mm = 1 3/8 inch diameter. Measure your radiator hose's outside diameter before ordering. ISR offers this adapter in multiple sizes for different hose diameters.
