Q

why my car engine light is on

When your car's check engine light comes on, it usually means the vehicle's electronic control system has detected an issue. This could be caused by something as simple as a faulty oxygen sensor, worn spark plugs, a problematic ignition coil, abnormalities in the fuel system, issues with the exhaust system, or even a loose gas cap. It's advisable to use an OBD - II scanner to read the trouble codes as soon as possible to pinpoint the exact problem, ignoring it for too long might lead to more serious damage down the line. Here in Malaysia, the hot and humid weather can speed up circuit aging or cause sensors to get damp, so regular circuit checks and keeping the engine bay clean are especially important. If the check engine light starts flashing or is accompanied by noticeable abnormalities like loss of power or strange noises, stop the vehicle immediately and contact a repair shop. This could indicate serious issues such as engine knocking or a damaged catalytic converter. During regular maintenance, make sure to use engine oil and fuel that meet the manufacturer's specifications, and replace the air filter regularly. These simple measures can effectively lower the likelihood of the check engine light being triggered. For newer models, the engine light might also be related to the emissions system; if left unresolved, it could cause you to fail your vehicle inspection, so prompt repairs are essential.

Q
Is 2017 a good year for Chevrolet Colorado?
The 2017 Chevrolet Colorado delivers solid performance and practicality, powered by a 2.8L Duramax turbo-diesel engine that offers strong low-end torque—ideal for hauling or towing—while maintaining decent fuel efficiency. The interior is function-first, featuring a 7-inch touchscreen with Apple CarPlay and Android Auto, so you’ve got the tech basics covered, though it’s hardly luxurious. Safety-wise, it comes standard with a rearview camera and stability control, but advanced driver aids are sparse. Reliability is generally good, though some owners note the stiff suspension tuning compromises long-distance comfort. As a midsize pickup, the Colorado strikes a balance between work and daily use, with a competitive bed size and payload capacity for its class. If you’re eyeing a used one, check service records—especially for the diesel engine—and inspect the undercarriage for local road wear. Cross-shop rivals like the Toyota Hilux and Ford Ranger; each has its strengths, so test-driving is key to deciding what fits your needs best.

Q
How much oil does a 2017 Chevy Colorado 2.8 take?
The 2017 Chevy Colorado with the 2.8L diesel holds about 6.0 quarts of oil (including filter). Stick with a full synthetic 5W-30 that meets dexos2 spec for best results – especially important in these Duramax turbo-diesels. If you're towing heavy or driving in extreme heat, consider shortening your change intervals to 5,000-6,000 miles. These engines are built tough but pay attention to oil consumption. The turbo setup runs hot, so check your dipstick regularly. Pro tip: Don't make the mistake some owners do by using gas-engine oil. Diesel-specific formulas have extra detergents and anti-shear additives – cheaping out here can clog your DPF or even toast the turbo. Always pair your oil change with a quality filter – the factory recommends ACDelco PF63 or equivalent. Those no-name filters? They'll cost you in the long run with poorer filtration. And if your Colorado has auto start-stop, good oil is crucial to prevent wear from those constant restarts. Last thing: If the truck's gonna sit for a while, check the oil condition first – diesel acids can do a number on internal parts over time.

Q
What is the resale value of a 2017 Colorado?
The resale value of a used 2017 Chevrolet Colorado depends on factors like condition, mileage, trim level, and service history. Current market prices typically range between RM60k to RM90k, with well-equipped 4WD models or low-mileage units holding their value better. Known for its durability and practicality, this pickup comes with either a 2.5L or 3.6L engine—both proven reliable in local driving conditions. Good parts availability also helps with its strong resale value. Compared to sedans, pickups like the Colorado tend to depreciate slower, making them ideal for buyers who frequently haul loads or tackle rough terrain. If you're selling, a complete service record and clean exterior can significantly boost buyer interest. For reference, check used prices of rivals like the Toyota Hilux or Ford Ranger, but final pricing should always be based on an actual inspection. Potential buyers should pay extra attention to the chassis condition and engine noise—off-road use in previous ownership could affect long-term reliability.

Q
Are 2017 Chevy trucks reliable?
The 2017 Chevy pickup trucks offer above-average reliability, with their proven EcoTec3 V8 engines and 6-speed automatic transmissions showing lower powertrain failure rates. However, some owners report occasional glitches in electronics like the MyLink infotainment system. Built with high-strength steel frames, these trucks earned NHTSA's 5-star safety ratings, making them solid choices for frequent long-haul driving. One thing to note: maintenance costs for American pickups tend to run slightly higher than Japanese rivals, especially with potentially longer part wait times for imported models. Always opt for GM-certified repair shops. Against competitors, the 2017 Ford F-150's aluminum body sheds weight, while the Ram prioritizes ride comfort—pick based on your needs. Pro tip: Regular transmission and differential fluid changes are crucial for extending drivetrain life in these big-displacement American workhorses.

Q
How is the 2017 Chevy Colorado transmission configuration?
The 2017 Chevrolet Colorado's transmission setup varies by trim and engine choice. Most models come standard with a 6-speed automatic (6L80), while some versions offer an optional 6-speed manual—both delivering smooth shifts and solid fuel efficiency. This midsize truck packs three powertrain options: a 2.5L four-cylinder, 3.6L V6, or a torque-rich 2.8L turbo-diesel ideal for towing and hauling. Gear count matters here: more ratios mean better power delivery and relaxed highway cruising, and Colorado’s 6-speed was the sweet spot for pickups back then—durable yet modern. Off-roaders will appreciate how its 4WD system pairs with the transmission’s low-range gearing, especially handy for Southeast Asia’s rough terrain.
