Ram Heavy-Duty Service | Terrace, BC
Ram Diesel and Heavy-Duty Truck Service in Terrace, BC
Maintenance for Ram 2500 and 3500 trucks that work for a living: the 6.7L Cummins, the emissions system, and everything that takes the strain of a heavy trailer.
A heavy-duty truck earns its keep hauling and towing. Its maintenance should be planned around that work.
Quick answer: Terrace Chrysler services Ram 2500 and 3500 heavy-duty trucks, including the 6.7L Cummins turbo diesel: oil and filters, fuel filters and water separator, DEF and exhaust after-treatment, cooling system, brakes, steering and towing equipment. Book online, by text or at 250-635-7187, Monday to Friday.
What diesel and heavy-duty service covers
1
Engine oil and filter
A large volume of heavy-duty diesel engine oil and a Mopar filter, on the interval the oil change indicator sets.
2
Fuel filters and water separator
Diesel fuel carries water and contaminants. The filters and separator keep them out of the high-pressure injection system.
3
DEF and after-treatment
Diesel exhaust fluid, the particulate filter and related sensors checked so the truck stays out of reduced-power mode.
4
Cooling system
Coolant condition and hoses checked. A diesel towing uphill makes a lot of heat.
5
Heavy-duty brakes
Pads, rotors and fluid on a truck that stops far more weight than a half-ton.
6
Steering and towing equipment
Front-end parts, hitch, trailer wiring and trailer brake connection inspected.

The 6.7L Cummins: what it needs
Clean fuel
Modern diesel injection runs at extremely high pressure and has very little tolerance for water or dirt. If the water-in-fuel light comes on, have it looked at soon. Fuel filters replaced on schedule are cheap insurance for injectors that are not.
Diesel exhaust fluid
DEF is used up as you drive and has to be topped up. Use fresh, sealed DEF and keep the cap clean. Contaminated or old fluid can trigger warnings and a derate.
Diesel particulate filter
The DPF traps soot and burns it off during regeneration. Long highway runs and towing help it clean itself. A truck that only does short trips may not get hot enough, and the soot builds up. If the truck tells you a regeneration is needed, give it a steady drive.
Exhaust brake
The exhaust brake uses the engine to slow the truck on long grades and saves the service brakes. Use it, and let us know if it stops working the way it should.
Towing and hauling
Towing is the reason most people buy a Ram 2500 or 3500, and it is also what the severe service schedule is written for. Heavy trailers shorten the intervals for oil, fluids and brakes, and put extra load on the steering and suspension.
- Tell us what and how often you tow when you book, so we plan the right service.
- Check trailer lights and the brake controller before every trip.
- Set tire pressures for the load. The placard on the door jamb shows empty and loaded figures.
- Watch the transmission and coolant temperatures on long climbs.
Diesel in a Terrace winter
Fuel gelling
Diesel thickens in extreme cold. Winter-blend fuel from local stations handles most of it. On trips into colder country, fill up locally and keep the tank topped up to reduce condensation.
DEF freezing
DEF freezes at about minus 11 degrees Celsius. The truck has heaters to thaw it, and it is designed to handle this, but a frozen DEF warning on a very cold morning is not unusual.
Block heater and batteries
A diesel starting in the cold asks a lot of its two batteries. Plugging in the block heater on cold nights makes starting easier on the engine and the batteries. We test both batteries at every visit.
Idling
Long idling in the cold is hard on a modern diesel and its emissions system. Warm up by driving gently after a short idle.

Ram diesel service FAQs
How often does a 6.7L Cummins need an oil change?
Follow the oil change indicator, which accounts for towing, idling and load. Heavy towing and lots of idling bring it forward, and the oil should be changed at least once a year.
How often should I change the fuel filters on my Ram diesel?
The interval is in your owner's manual and is shorter under severe service. Replace them sooner if the water-in-fuel light comes on or the truck loses power.
What happens if I run out of DEF?
The truck warns you well in advance, then limits speed and eventually will not restart until DEF is added. Keep it topped up.
Why does my truck keep asking for a regeneration?
Short trips do not get the exhaust hot enough to burn off soot in the particulate filter. A steady highway drive usually clears it. If the message keeps returning, book an inspection.
Does DEF freeze in winter?
Yes, at about minus 11 degrees Celsius. The truck has heaters to thaw it, so a frozen DEF warning on a very cold morning is not unusual.
Do you service the gas-engine Ram 2500 and 3500?
Yes. We service Ram heavy-duty trucks with both the 6.4L HEMI and the 6.7L Cummins.
