Monitor coolant pressure and temperature through one M12 x 1.5 port with this Lowdoller combo sensor.
Reading both pressure and temperature from a single sensor saves a port, a second sensor and a second run of wiring, making it ideal where space is tight. Perfect for engines with metric coolant ports.
