Water Temp Sensor Adapter – GReddy 34 mm Radiator Hose Temp Sender Adapter (Part No. gre16401634)

Water temp sensor adapter is your no-nonsense solution to get real, accurate coolant readings right where it matters. With the GReddy 34 mm radiator hose temp sender adapter (Part No. gre16401634), you insert the sensor inline in the flow—no guesswork, no heat soak, just honest data.

Say goodbye to slow or lagging temperature readings. This adapter installs directly in the radiator hose, placing the sensor right into the coolant path. You’ll get faster response times, better gauge accuracy, and more confidence when pushing your ride hard.

Built for speed junkies and daily drivers alike, the GReddy version comes in a 34 mm diameter designed to match high-flow hoses. It’s engineered to maintain flow while giving you a perfect port for your temp sender.

Features and Benefits

  • 34 mm Hose Diameter – Fits standard big-block radiator hoses without restricting coolant flow.

  • Inline Installation – Installs directly in radiator hose for real-time readings right in the coolant stream.

  • Precision Sender Port – Accepts common temp senders (e.g. 1/8″ NPT) to ensure compatibility with aftermarket gauges.

  • Durable Construction – Made of robust materials to resist vibration, heat, and coolant corrosion.

  • OEM-Grade Design – Maintains coolant seal integrity; doesn’t leak or cause flow turbulence.

Never Guess Your Engine Temp Again

Tired of guessing whether your engine’s cooking or cruising? With this water temp sensor adapter, you get the real story—accurate coolant readings as soon as heat builds. No more dummy readings, no more surprises.

Installed this GReddy water temp sensor adapter on my '99 Mustang GT and it fits perfectly! Super easy install and the readings are spot on now. Totally worth it for peace of mind on hot Texas days.

Used this adapter for my Subaru WRX build out here in Portland, OR. The install was clean, no leaks, and the gauge reacts instantly now. Feels like a pro setup for a DIY price!
