Hi there - the temperature gauge behavior you describe would indicate that you need a new thermostat. The thermostat should keep engine temperature within a close range - close to the center of the gauge from a visual point of...

Hi Lawrence. Thanks for stopping by tonight. If you turn the key and you have electrical power to the accessories (like the lights, radio, etc.) then the fault is either a damaged ignition relay, starter relay or faulty starter. If...

Hello. If your monitors are showing not ready, then that is because the computer was recently reset or the battery may have been replaced. If either of these occurred, then there is a specific amount of driving that needs to...

Realize that green antifreeze is the old style antifreeze. That was an old type of antifreeze where the glycol lasts maybe three years max. So you've got to change the coolant maybe three years or every 15,000 miles. The modern...

Typically, when the Check Engine Light is illuminated and it is flashing, this is an indication that the vehicle's engine is misfiring. This would also explain the symptoms on your 2007 Lincoln MKZ. If the engine has a misfire, then...

The release for the foot-operated parking brake is right above the parking brake pedal. The parking brake release is a large handle with a “P” on it. To release the parking brake, pull on the handle until you hear the...

It really depends on how you deal with the system. Some guys are worried about damaging the brake master cylinder. So they open the bleeder valve on the brakes and then squeeze the caliper back in when they change the...

Hi there - while a big drop in temperatures shouldn't cause a service light per se, cold temperatures DO have an effect on electrical connections, and a connection problem may be the case here. You need the actual problem code...

You may need to look at the code P0122 since it pertains to the throttle position sensor and this can affect all the drive symptoms you are having. The O2 sensor readings seem to be normal and you are not...

The vehicle is equipped with a number of gauges on the instrument panel, located in the dashboard behind the steering wheel. These relate information to the driver, and the driver barely needs to look away from the road to monitor...

Hi there. I've seen this same concern during my tenure as a Nissan service manager. What usually happens is the wire harness to those sensors becomes brittle and loose. When this happens, it does need to be replaced/repaired. The odds...

The radiator replacement and the present no start problem are just coincidences. Check to see if there are any stored diagnostic trouble codes. Be sure you have a fully charged battery that passes an actual load test. Confirm that the...

When the oil pressure light comes on, the engine oil is loosing oil pressure. I recommend performing an oil change and filter change with a good brand filter. If the light is still coming on, then hook up a mechanical...

Hi There, It sounds like you may have a faulty cam position sensor that may be causing the jerking reaction (which is normal when the cam sensor begins to fail), resulting in the traction control system to engage. The camshaft...

Hi there. Although it is possible that you have an electrical short on a wire heading to the rear or powering the rear blinker, it is more likely that you have an electrical relay or fuse issue. Most wires on...

Hello. There may be a couple things going on here. If the steering wheel is indeed locked in position, the steering lock mechanism behind the steering wheel may be stuck and in need of a replacement. If the steering wheel...

The electronic control unit (ECU) used in today’s cars and trucks is used to control the engine and other components’ functions. An ECU is a computer with internal pre-programmed and programmable computer chips that is not much different from a...

Hi there. In most cases, this type of clicking sound is caused by a belt that is slightly frayed and hitting a shield or other mechanical component. It's also common for a worn out pulley or idler tension pulley to...

This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer...

Relays are always a good location to test a system. You are on the right track in that respect. Unfortunately, your car does not have a traditional fuel pump relay. It has what is known as the Fuel pump driver...
