Hi Ruben. Thanks for contacting us today. The sensors that will monitor data are the engine temperature sensor and the coolant temperature sensor. They work together to relay data to the ECU. If the engine temperature is too hot, an...

The HHR comes with two different motor options, so this complicates my answer a bit. Either way, the best method is to follow the hose at the brake vacuum booster to where it connects on the motor. Even better, simply...
