Hybrid Racing K Swap Coolant Temp Sensor Adapter
Swapped a K series into your EF, EG, EK, DC, or DA chassis and now your factory temp gauge doesn't work? The Hybrid Racing coolant temp sensor adapter fixes that. Your factory cluster's looking for the two-wire B or D series coolant sender, but the K series uses a completely different sensor. This adapter screws into the unused idle air assist valve port on your K series water neck and gives you the correct threads to bolt in your temperature sensor. Your temp gauge works just like it did with the original engine. No splicing wires, no inline adapters, no recalibration.
Uses the Factory Idle Air Assist Port
The K series water neck has a port for the idle air assist valve that most people delete during a swap. This adapter threads into that port and provides the correct internal threads for a B or D series coolant sender. You're using a port that's already there instead of splicing into a coolant hose or drilling and tapping something that wasn't meant to have a sensor.
CNC Machined 6061 Aluminum
The adapter's CNC machined from 6061 aluminum and hard anodized black. The anodizing resists corrosion and the aluminum handles the heat without issue. It's not a cheap brass fitting that'll corrode or a plastic adapter that'll crack from heat cycles.
No Hose Splice Adapters
Most people use inline hose adapters to splice the coolant sender into a coolant line. Those adapters take up space, look ugly, and they're another potential leak point. This adapter bolts straight to the water neck using a port that's already there, so your engine bay stays clean.
