The The “h” stands for hybrid, and while you might hope to get greatly improved gas mileage for your effort to go green, that shouldn’t be your motivation for buying this model. The 600h L offers a mere 1 mpg...
With With a four-generation legacy spanning a quarter of a century, the Lexus LS may not be the riskiest, most cutting-edge vehicle in its class but its devotees don’t mind – the reliability, near perfection of design, and pronounced bent...
Measure fuel pressure on the fuel rail. If the pump turns on, that's hopeful but it doesn't mean there is actual pressure. Also, check for actual injector operation using a noid light. Is there an actual spark at the spark...
Hello. There can be several components that will cause the heater (https://www.yourmechanic.com/services/heater-is-not-working-inspection) to fail. Always start with the simple options first. The heater relies on hot coolant from the engine entering the heater core where air is pushed over it...
Although this is a common issue on this generation of the Lincoln LS model, engine misfires can be caused by many different problems and are generally caused by either a spark or fuel issue or in some cases, a combination...
I would not think an O2 sensor would cause a stall and no or hard restart. I would think you have a problem with a fuel pump or pump power supply problem. This could cause O2 sensor codes if vehicle...
Hi Shae. Thanks for contacting us today. It's a good idea to let the charging system fully charge before attempting to jump start the vehicle. Some of these units require you to not have them plugged in, so you'll have...
The existing motor can be rebuilt. Used motors are available, too, for example from services such as Car-Part.com (http://www.car-part.com). However, used (junkyard) motors carry a risk. If you rebuild what you have, or buy an off the shelf rebuilt motor,...

If the thermostat housing is leaking after you replaced the thermostat then you either did not seat the thermostat correctly or the housing is cracked. Remove the housing to check for cracks.
The problem may not be a leak, but a malfunctioning water pump assembly (https://www.yourmechanic.com/services/water-pump-replacement) or faulty thermostat (https://www.yourmechanic.com/services/thermostat-replacement). Make sure the drive belt is properly routed and has good tension. If the coolant isn't flowing properly, the coolant in the...
If the vehicle is leaking fuel, I would stop driving it immediately, and have it serviced as soon as possible. Gasoline is highly flammable, and therefore it is not safe to drive a vehicle that is leaking fuel. I would...
The most common noise that Lincoln LS owners hear is from the brakes, or a bad wheel bearing. If the noise is a scraping sound, it's likely the brakes. If the car is making a grinding, roaring noise that changes...
To identify the cause of poor operation like that you are describing, the cylinder firing patterns have to be looked at on a scope. That diagnostic reveals whether the issue is fuel or ignition related and also which cylinders are...
Loosing the serpentine belt should not affect the engine timing. But it sounds like you have some other problem. The first thing that comes to mind is that the harmonic balancer may be coming apart. The harmonic balancer is a...

I would suggest having a professional from...
