Very cold weather start Diesel 2018 Terrain
2018 Diesel Terrain Starting in very cold weather -32 degree C
For those like me who are new to a diesel application, and new to the 2018 Diesel Terrain, here are a few advises on how to start the engine in very cold weather, -32 degrees C without wind factor.
As you get in the car, shut down the headlamps right away as during night operations they may come on automatically
Make sure ventilation, audio system, interior lights, wipers front and rear, and all other possible accessories are turned OFF
Push the start button for 10 seconds... do not press on the brake pedal , you do not want to start the engine at this time
The accessories mode will come on
Leave the multiple computers and sensors, networks communicate with each other for about 20 seconds
Now push on the brake and the start button and crank starter for about 15 seconds. If the engine has not started, rest the starter for one minute, then cycle the starter again for 15 seconds
The French instruction manual (Quebec, Canada) says to press the brake pedal and push the start button right away, i find this is not a good technique in very cold weather and tends to flood the engine
If the engine is flooded, push the brake pedal , and the accelerator to the floor, both in the same time, then start the engine for 15 seconds at a time. Slowly the engine will come to life as you crank. ( the French instruction manual omits to press on brake pedal )
Once the engine is started, make sure you shut down the headlamps, and leave all accessories OFF. You will want the battery and alternator power to be available for the Diesel line heater, and the diesel fuel tank heater. At start up , the low impedance glow plugs consume 80 amperes, thats 20 amps each and there are four glow plugs.
The diesel line heater also comes on.
The current needed to supply the glow plugs, diesel fuel line heater and fuel tank heater is big business, so you dont want to start the heated seats, rear defogger, electrical auxiliary heater blower right away.
Leave the engine run for about 15 minutes to warm up before engaging any additional electrical load. In this matter, the electrical circuits can recharge the battery, and keep the heated diesel fuel warm
The 2018 diesel Terrain comes with an auxiliary heater, this is a fast way to obtain warm air in the car while the engine is cold. However, this is additional load for the electrical circuits, and it may be wise to hold for warm air from the engine before asking warm air from the auxiliary heater. As the diesel engine warms up and you start driving the car, you will notice the heat of the engine is up almost as fast as a gasoline engine, this is due to the front grill that shuts close as the engine is cold. Thus the engine is not cooled by exterior air and warms quickly, the auxiliary heater will shut down and warm air will come from the engine
There is a controller that will disable any electrical load not requested to operate the engine, and you will loose the heated seats for example if the electrical load is too high
Draining the battery and engaging a high load in extreme cold weather -32 C will affect the way the car will start on next start in extreme cold weather. You do want to leave a good charge to start the engine the next time around, ie next morning for exemple
The 1.6 CDT Diesel was designed by Torino in Italy, (city of Turin). The engine is then built by Opel in Germany. A fantastic engine that will start at -32 C no issues, just like a gas engine
But you need to understand the complex systems and give it a chance. The starting procedure is automated, and the limiting current computers will disable loads that are not necessary or loading the system, and if we unload the electrical load on the electrical system manually this will give a much better chance to get the engine started in extreme cold conditions...your battery is part of cranking the engine, so make sure you have a good potential on that battery for those extremely cold mornings..
