Automotivemechanicalparts 158-0421 Coolant Temperature Sensor Connector: Direct replacement for Toyota vehicles
Think of it as the nervous system's handshake for your car's brain. The Coolant Temperature Sensor Connector is that unassuming but vital automotive bit, built to swap out any dodgy or busted connectors in the engine's cooling setup.

Dodge headaches like engine meltdowns, lousy gas mileage, or that annoying check engine light; this little gadget smooths out your ride and helps your engine go the distance. Just unplug the old one, snap this in, and you're back on the road, sidestepping pricey garage bills with a simple fix.
