Altima driver's window won't close in one touch

A It seems the window safety switch thinks the glass has hit something -- like fingers! -- before fully closing. This causes the window to reopen several inches to free any pinched pinkies.

When it's time for a coolant change, does the type matter?

As coolants and engine technology continue to improve, I've softened my position on coolant changes. Assuming a long-life coolant and 15,000-25,000 annual mileage, I'm willing to go five years now -- a huge step for me!

Plastic spray nozzle might be lost in Sea Ray's engine

The red plastic straw got sucked into a four-cylinder GM engine on a 1972 Sea Ray boat. Now what?

Check Engine light is on, and mechanic's not helping

What's interesting about this question is that the mechanic is trying to pinpoint the problem by asking the car owner to do all the work!

Nissan Sentra burns up oil, but only on the highway

A Ah, such fond memories. My old Jeep Grand Wagoneers used to suffer this problem. The engines were "tired" -- lots of miles on them on the big V-8's - so the excess combustion blow-by into the crankcase overwhelmed the PCV system's capability to draw these vapors into the induction system and burn them. The excess crankcase pressure also forced oil past the piston rings as well as into the PCV system, progressively choking it off and causing high oil consumption. Back then I had a simple fix: Replace the PCV valve every six months and "roto-rooter" out the PCV passages with part of an old speedometer cable.

It's not easy to bring back tires once uneven wear starts

The rear tires are cupping, and the fronts are becoming louder and louder. What is going on?

Finding source of Tracer's stalling will take sleuthing

A When dealing with drivability issues, always remember the "KISS" principle -- start with the simple stuff first. In this case, the reason the engine continues to idle with the air conditioning engaged is the step-up in idle speed commanded by the powertrain control module (PCM). The first things to try would be to clean the injectors and decarbonize the induction system with a fuel system/fuel injection cleaner like Sea Foam or GM's Top Engine Cleaner. Then check for any type of vacuum leak that could lean out the idle. And check for splits or tears in the rubber boots and hoses downstream from the throttle body and MAF (mass airflow sensor). The idle speed should be 780 rpm (plus or minus 50 rpm) with the air conditioning off.

Speedometers can reach stratosphere for a reason

Most new cars and a lot of used cars have speedometer gauges that go as high as 120 to 160 miles per hour. Why so high?

Found under Buick's hood: Free addition to your toolbox

When a broken serpentine belt got changed, there was a pair of Vise-Grips with pieces of rubber hose over each end pinching off the overflow hose just below the radiator cap.

An intermittent 'stumble' could be the spark plugs

When the 2003 Hyundai Sonata with the 2.7-liter V6 engine and 110,000 miles is idling in drive, it feels like the engine is randomly stumbling, one sharp stumble at a time.
