If I install bigger wheels on my Nissan Juke, will this affect vehicle handling?
Fitting in larger wheels into your Nissan could alter some handling characteristics of the vehicle. The key here is to not overdo the plus-sizing. If this is done within the acceptable range (the recommended range is no more than plus 3), larger wheels may bring in better cornering and improved handling capabilities. Along with this, you may enjoy more responsive steering. However, if the wheels are too large, steering can be adversely affected. This can put a lot of strain on the brakes as well as steering and suspension parts, which can be blamed on the increase in rotational mass and weight.
Can old factory lug nuts/bolts be used with the new aftermarket wheels of my Nissan?
The factory lug nuts/bolts can be re-used with the aftermarket wheels if these wheels are designed with the same type of seat as the factory wheels. It depends on the compatibility or fit. Most factory lug nuts, however, don't usually fit. That's why most would find themselves buying a new set of lug nuts that will be suitable to the aftermarket wheels' lug seats. If you don't find a suitable set of lug nuts, then the wheels could be out of balance. The nuts would stay loose as well after a while. This wouldn't be safe. When installing new wheels, be sure to find the right type of lug nuts and bolts to use. The lug nuts or bolts should engage easily and secure the wheels properly.
There's white smoke exiting the tail pipe of my Juke? Where could this smoke come from? What does it mean?
It's not unusual for white vapor to come out of the exhaust tail pipe of your vehicle when it's cold. The presence of vapor is due to condensation in the exhaust. As such, water drops from the tail pipe is also normal under this condition. However, if white smoke comes out of the vehicle when it's warm, this could be a sign of burning coolant. Coolant may have leaked into the cylinders and have mixed with the air-fuel combo. When there's burning coolant, the coolant level in the overflow bottle or radiator would drop. The burning coolant could be a result of a cracked head or block or a blown head gasket. For your safety, have the engine checked right away and fix the problem first before driving the vehicle.
I can't trace the radiator leak in my Nissan. Would it be all right if I pour some dish detergent in the radiator to find where the leak is coming from through the bubbles? Is this a safe trick? This is recommended by a friend.
Instead of putting dish detergent in the radiator, which isn't highly advised, you could instead use a UV light detection system or a pressure tester to find the leak. This will be a safer and an even more reliable method of tracing the source of the radiator leak.
