FAQs—Chevrolet C6500 Kodiak
When I checked the motor oil of my Chevrolet C6500 Kodiak, I was surprised to see that the oil appears milky brown. What did the color of my engine oil change to this? Is this normal? Or should I worry about it?
If you found out during the oil check or change that the engine lubricant has changed its color to milky brown, chances are, there's coolant in oil. Coolant may have mixed with oil due to a leak. This leak can be traced to a blown head gasket, a cracked case, or a faulty transmission cooler. You have to find where the leak is coming from and how the coolant escapes into the oil system. You shouldn't ignore this. Instead, you should have things checked to get answers right away and find the right solution for stopping leaks.
What causes tires to wear out unevenly?
The uneven tire wear can be caused by numerous factors such as improper inflation. Wear on both edges mean that the tires don't have enough air pressure. If wear is focused on the center, this indicates over inflation. A toe-in problem is hinted through the tire's feather edge wear, while camber alignment or adjustment may be needed if wear is spotted on the one side edge. Check the tread of the tires to know if the tires are already up for replacement or just need some repair or adjustments. Don't let your tires get damaged fully. This is dangerous. Your vehicle's drivability and stability will suffer along with ride quality. If the tires aren't in their best shape, you can't expect to get good traction, especially when the vehicle is driven in rain, mud, snow, or wet conditions.
Is it a good idea to have the A/C system service done as a DIY?
Specialist tools and equipment are needed for the service. The service is quite complicated since the system is under high pressure. This pressure should then be reduced to a near total vacuum to remove moisture. The refrigerant should also be handled with great care due to its low boiling point. This can cause freeze burns. Another thing to consider when handling refrigerant is how this will be disposed. It would be illegal if the refrigerant is dumped into the environment. There are certain rules to follow for proper disposal.
Why is ultraviolet dye in the A/C system? Can this help really trace the leak?
The UV dye helps find the source of the leak. Under a UV light source, the dye is highly visible. This will point to where the leak is coming from. This is used for A/C system problem diagnosis and for determining the faults in the system.
If I add some extra weight on the vehicle, should I consider adding more air pressure in the tires?
This can be done to help the tires adjust and cope with the added weight on the vehicle. With the extra weight, about 5 pounds can be added to the prescribed air pressure by the manufacturer. This, of course, depends on manufacturer instructions. Even if you can add more air pressure in the tires, the vehicle shouldn't be overloaded, as this can cause the tire cord to break. Heat may also build up due to unusual sidewall flexing.
